if the percent of solute in an aqueous solution is 5%, what is the percentage of water in that solution?

Answers

Answer 1

Answer: The percentage of water in the solution would be 95%.

Explanation:

The percent composition of a solution refers to the amount of each component in the solution as a percentage of the total solution. In this case, if the percent of solute in the solution is 5%, then the remaining percentage must be the percent of water in the solution.

Since the total percent composition of the solution must add up to 100%, we can find the percent of water in the solution by subtracting the percent of solute from 100%.

% Water = 100% - % Solute

% Water = 100% - 5%

% Water = 95%

Therefore, the percentage of water in the solution is 95%.

during chemical weathering, sodium is released as dissolved ions and transported to the ocean, where:

Answers

Answer: During chemical weathering, sodium is released as dissolved ions and transported to the ocean, where it increases the salinity of the seawater.

Salinity is a measure of the amount of salt in seawater. The greater the salinity, the more salt there is in the water. The salinity of seawater is expressed in parts per thousand (ppt). There are about 35 ppt of salt in seawater.

Chemical weathering is the breakdown of rocks by chemical reactions, resulting in the formation of new minerals. Water is the most common medium for chemical weathering because it can dissolve many minerals. Carbon dioxide, oxygen, and organic acids are also involved in chemical weathering.

Sodium is a common element in minerals that are subject to chemical weathering. When rocks weather, sodium ions are released into the water. Rivers and streams transport these dissolved ions to the ocean, where they accumulate over time.

This is why seawater has a high concentration of sodium ions. Sodium is also introduced into seawater through underwater volcanoes and hydrothermal vents.

Sodium is important for many organisms that live in the ocean. It is an essential nutrient for marine animals, and it plays a role in regulating the body fluids of fish and other aquatic animals. Sodium is also important for maintaining the pH of seawater.

The concentration of sodium in seawater can also have an impact on ocean currents and the movement of water around the world.

a mixture of three gases has a total pressure of 1,380 mmhg at 298 k. the mixture is analyzed and is found to contain 1.27 mol co2, 3.04 mol co, and 1.50 mol ar. what is the partial pressure of ar? multiple choice 0.258 atm 301 mmhg 356 mmhg 5,345 mmhg 8,020 mmhg

Answers

The partial pressure of Ar is 0.219 * 1,380 mmHg = 301 mmHg.

The partial pressure of a gas in a mixture is equal to the mole fraction of that gas times the total pressure of the mixture.

The mole fraction of Ar in this mixture is 1.50/6.81 = 0.219. Thus, the partial pressure of Ar is 0.219 * 1,380 mmHg = 301 mmHg.

The ideal gas law states that the pressure of a gas is directly proportional to its number of moles and inversely proportional to its volume.

This law is expressed in the equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

In a mixture of gases, each gas behaves independently according to the ideal gas law. Thus, the total pressure of the mixture is the sum of the partial pressures of each gas.

The partial pressure of a gas is equal to its mole fraction times the total pressure. The mole fraction of a gas is the number of moles of that gas divided by the total number of moles of all gases in the mixture.

In the example provided, the total pressure of the mixture is 1,380 mmHg, the number of moles of CO2 is 1.27, the number of moles of CO is 3.04, and the number of moles of Ar is 1.50.

The total number of moles of all gases in the mixture is 1.27 + 3.04 + 1.50 = 6.81. The mole fraction of Ar is 1.50/6.81 = 0.219. Thus, the partial pressure of Ar is 0.219 * 1,380 mmHg = 301 mmHg.

Consider the Baeyer permanganate test and chromic acid tests. These tests work by converting an aldehyde to what functional group? 1 KMnO4 and H2CrO4 act as what kind of reagent? (e.g. electrophile, nucleophile, oxidizing agent, reducing agent, acid catalyst, base catalyst, solvent etc.) 2. 3. Why does a ketone not react with these reagents?

Answers

The Baeyer permanganate test and chromic acid tests work by converting an aldehyde to a carboxylic acid functional group.

KMnO₄ and H₂CrO₄ act as oxidizing agents. A ketone does not react with these reagents because it does not have a hydrogen atom attached to the carbonyl group.

How does the Baeyer permanganate test work?

The Baeyer permanganate test is used to identify the presence of unsaturation (i.e. double bonds) in a compound. When a double bond is present in the compound, it will be oxidized by potassium permanganate (KMnO₄) to form a diol functional group. In the case of aldehydes, the double bond is present between the carbonyl carbon and the hydrogen atom.

Therefore, the reaction will convert an aldehyde to a carboxylic acid functional group. This reaction is also known as the oxidation of aldehydes with KMnO₄.

What is the chromic acid test?

The chromic acid test is another method for identifying the presence of unsaturation in a compound. It uses chromic acid (H₂CrO₄) as the oxidizing agent. Like the Baeyer permanganate test, the chromic acid test will convert an aldehyde to a carboxylic acid functional group. It is important to note that the chromic acid test is more sensitive to the presence of double bonds than the Baeyer permanganate test.

Therefore, it is often used as a confirmatory test after a positive result is obtained from the Baeyer permanganate test.

what is the ph of an aqueous solution that is made by mixing 200 ml of 0.20m nah2po4 and 200 ml of 0.60m na2hpo4 at 25oc?

Answers

Answer: The pH of the solution is 9.22.

Explanation:

The given solution is a mixture of 200 mL of 0.20 M NaH2PO4 and 200 mL of 0.60 M Na2HPO4. NaH2PO4 is a weak acid and Na2HPO4 is a weak base. When they are mixed, they undergo a buffer solution.

The Henderson-Hasselbalch equation for a buffer is:

pH = pKa + log ([A-]/[HA])

Where,

pKa = -log Ka (dissociation constant of the acid)

[HA] = concentration of the acid (NaH2PO4)

[A-] = concentration of the conjugate base (HPO42-)

The pKa value for NaH2PO4 is 7.21 (at 25°C). The concentrations of the acid and the conjugate base can be calculated as follows:

For NaH2PO4:

moles of NaH2PO4 = 0.20 M x 0.2 L = 0.04 mol

concentration of NaH2PO4 = 0.04 mol / 0.4 L = 0.10 M

For Na2HPO4:

moles of Na2HPO4 = 0.60 M x 0.2 L = 0.12 mol

concentration of Na2HPO4 = 0.12 mol / 0.4 L = 0.30 M

Using the Henderson-Hasselbalch equation and substituting the values:

pH = 7.21 + log ([HPO42-]/[H2PO4-])

pH = 7.21 + log (0.30/0.10)

pH = 9.22

Therefore, the pH of the solution is 9.22.

The pH value of the resulting solution assume the volume of the solution is not affected by this addition is 3.283.

The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

In this Question, HF is a Weak Acid and RbF is a weak Base - HNO3  is a strong acid.

HF reaction in aqueous medium

HF +  H2O  --------- H3O+  + F -  

RbF +  H2O  ----  Rb+ +  F -

pH (Original)  =  pKa  +  log ( [salt ] / [Acid] )  

We donot need to calculate pH original -which is for the original solution before adding the strong acid.

HF is a weak acid - so in a buffer solution its dissociation is negligible - so it does not affect the H+  ion concentration much.

When a 0.012 mol of HNO3  is added to the buffer solution , it dissociates in H+ and NO-3  .

H+ ions dissociated from the Acid react with F -  and produce HF . As a result the acid concentration will increase to the extent of 0.012 mol  and the salt concentration reduces by the same extent - 0.012 mol.

So the formula for New pH changes to

pH (New)  =  pKa  +  log ( [salt ] - 0.012 mol / [Acid] + 0.012 mol)

Here , 0.012 mol are added to 281 mL solution,

Concentration of HNO3,  M = number of moles / Vol in litres  

                                            =  0.012 mol / 281 mL

                                            =  0.012 mol / 281  / 1000

                                           = [0.012 mol x 1000]  / 281 L  =  0.043 M

As pKa = -log(Ka)  ,  

Given  [salt ] =  0.480 M ,  [Acid] =  0.318 M

                   = - log(Ka) +  log [ (0.480 M - 0.043 M) / (0.318 M + 0.043 M) ]

According to the given data, the compound citric acid contains 37.51% C, 4.20% H, and 58.29% O by mass. So, let's assume that we have 100 g of citric acid, and then, we can find the masses of each element present in it: Mass of carbon = 37.51 gMass of hydrogen = 4.20 g. Mass of oxygen = 58.29 g.

Next, we need to convert the masses into the number of moles using the molar masses of the elements. The molar mass of carbon = 12.01 g/mol, Number of moles of carbon = 37.51 g / 12.01 g/mol = 3.124 molMolar mass of hydrogen = 1.01 g/molNumber of moles of hydrogen = 4.20 g / 1.01 g/mol = 4.158 molMolar mass of oxygen = 16.00 g/molNumber of moles of oxygen = 58.29 g / 16.00 g/mol = 3.643 follow, we need to find the simplest whole-number ratio of these moles by dividing them by the smallest number of moles, which is 3.124 mol: Carbon = 3.124 mol / 3.124 mol = 1Hydrogen = 4.158 mol / 3.124 mol = 1.33 ≈ 1Oxygen = 3.643 mol / 3.124 mol = 1.17 ≈ 1So, the empirical formula of citric acid is CHOS or C3H4O3.

find the pka of an acid which has an initial concentration of 1.497 m for the acid and an equilibrium ph of 2.546.

Answers

Answer:

From the equilibrium pH, we can find the concentration of H+ ions in solution using the relation:

[H+] = 10^(-pH)

[H+] = 10^(-2.546) = 2.177 × 10^(-3) M

Now we can use the fact that the acid is a weak acid and only partially dissociates to form H+ ions and its conjugate base. Therefore, we can assume that [HA] at equilibrium is equal to the initial concentration of the acid minus the concentration of H+ ions that were produced from the dissociation of the acid.

[HA] at equilibrium = initial concentration of acid - [H+]

[HA] at equilibrium = 1.497 M - 2.177 × 10^(-3) M

[HA] at equilibrium = 1.497 M (since the concentration of H+ ions is negligible compared to the initial concentration of the acid)

Now we can plug in the values we obtained into the Henderson-Hasselbalch equation:

2.546 = pKa + log([A-]/[HA])

2.546 = pKa + log(0/[HA])

2.546 = pKa - log([HA])

log([HA]) = pKa - 2.546

[HA] = 10^(pKa - 2.546)

Since we assumed that the concentration of the conjugate base at equilibrium is negligible, we can assume that [A-] ≈ 0.

Therefore, we have:

pKa = log([HA]/0) + 2.546

pKa = log([HA]) + 2.546

pKa = log(1.497) + 2.546

pKa = 0.174 + 2.546

pKa = 2.72

Therefore, the pKa of the acid is approximately 2.72.

As electrons are passed down an electron transport system protons are pumped across a membrane.

The correct answer is option C.

When electrons pass through the electron transport chain, they lose energy. As low-energy electrons break down oxygen molecules and produce water, high-energy electrons from NADH or FADH2 complete the chain. The electron transport pathway produces three molecules of water for every three carbon sugars broken down during aerobic respiration.

This means that when six carbon sugars are broken down, six molecules of water are produced. The end products of electron transport include NAD+, FAD, water, and protons. Since protons are propelled through the crystal membrane by the free energy of electron transport, they exit the mitochondrial matrix.

Answers

The pH for a titration of 25.0 mL of 0.365 M acetic acid when 10.3 mL of 0.432 M NaOH have been added is approximately 4.69.

The pH for a titration of 25.0 mL of 0.365 M acetic acid when 10.3 mL of 0.432 M NaOH have been added can be calculated using the following steps:

1. Calculate the moles of acetic acid (CH₃COOH) and sodium hydroxide (NaOH) before the reaction:

- Moles of CH₃COOH = volume × concentration

= 25.0 mL × 0.365 mol/L

= 9.125 mmol

- Moles of NaOH = volume × concentration

= 10.3 mL × 0.432 mol/L = 4.4456 mmol

2. Determine the moles of acetic acid and sodium hydroxide remaining after the reaction: Since acetic acid and sodium hydroxide react in a 1:1 ratio, the limiting reactant will be NaOH.

- Moles of CH₃COOH remaining = 9.125 mmol - 4.4456 mmol = 4.6794 mmol - Moles of NaOH remaining = 0 mmol (all NaOH is consumed in the reaction)

3. Calculate the concentration of acetic acid and acetate ion (CH₃COO-) after the reaction:

- [CH₃COOH] = moles of CH₃COOH remaining / total volume

= 4.6794 mmol / (25.0 mL + 10.3 mL)

= 0.12998 mol/L

- [CH₃COO-] = moles of NaOH consumed / total volume

= 4.4456 mmol / (25.0 mL + 10.3 mL)

= 0.12346 mol/L

4. Calculate the pH using the Henderson-Hasselbalch equation:

pH = pKa + log([CH₃COO-] / [CH₃COOH]) pKa of acetic acid is 4.76, so:

pH = 4.76 + log(0.12346 / 0.12998) ≈ 4.69

Because a large substituent is more stable in an ___ position than in an ____ position, elimination of the ___ isomer occurs through its more stable chair conformer, whereas elimination of the ___ isomer has to occur through its less stable chair conformer. The ____ isomer, therefore, reacts more rapidly in an E2 reaction
equatorial cis axial
trans

Answers

In order for a six-membered ring to undergo an E2 reaction, the substituents that are to be eliminated axially must both be in equatorial positions.

This is because when bromine and an adjacent hydrogen are both in axial positions, the large tent-butyl substituent is in a cis position in the trans isomer.

Because a large substituent is more stable in a cis position than in an axial position, elimination of the trans isomer occurs through its more stable chair conformer, while elimination of the cis isomer has to occur through its less stable chair conformer. The cis isomer, therefore, reacts more rapidly in an E2 reaction.

because the more stable conformer has to be destabilized in order for the reaction to proceed. As a result, the reaction rate is much higher for the trans isomer than for the cis isomer.

the density of normal water (tghe hydrogens do not have neurons) at 20c is 0.9982 g/ml. calculate the density you would expect for heavy water by assuming the deuterium is the same size as normal hydrogen when it is poart of the water

Answers

The density of heavy water at 20°C is 1.107 g/mL.  


At 20°C, the density of normal water is 0.9982 g/ml.

The density of heavy water, which is composed of two atoms of deuterium instead of hydrogen, we must consider the difference in size between hydrogen and deuterium atoms.

Although the atomic masses of hydrogen and deuterium are slightly different, the difference in size is more significant, with deuterium atoms being about twice the size of hydrogen atoms.

Thus, when deuterium atoms are part of the water, the overall density of the water is greater.

This can be quantified using the following equation:

Density (heavy water) = [2*mass of hydrogen + mass of deuterium] / [2*volume of hydrogen + volume of deuterium]

The density of heavy water at 20°C is 1.107 g/ml, which is about 11% higher than that of normal water.

This increase in density is due to the larger size of deuterium atoms when compared to hydrogen atoms.

In conclusion, the density of heavy water at 20°C can be calculated by accounting for the difference in size between hydrogen and deuterium atoms.

This yields a value of 1.107 g/ml, which is 11% higher than that of normal water.

Which water is distributed on Earth from the greatest to the least

Answers

The water distributed on Earth from the greatest to the least is saltwater, freshwater, and frozen water.

Saltwater occupies 97.5% of Earth's total water. Freshwater occupies only 2.5% of Earth's total water. This freshwater is found in different forms, such as rivers, lakes, underground, and glaciers. Only 0.3% of freshwater is found in rivers and lakes, while 30% is stored underground. The rest of freshwater is stored in glaciers and polar ice caps.

The frozen water found on Earth is 1.7% of the total water. It is found in glaciers, ice caps, and snow cover around the poles. The water cycle is a natural process that allows water to move from one place to another on Earth. It is also called the hydrologic cycle. It involves the movement of water between the earth, air, and ocean.

Water evaporates from the surface of the earth, which forms clouds. The clouds then precipitate as rain, snow, or hail. This precipitation may fall on the land and join rivers and lakes, or it may seep into the ground and form underground water. The underground water may then resurface as springs or streams, which then join rivers and lakes.

The water cycle helps to purify water and replenish freshwater resources on earth. It also helps to regulate the Earth's temperature by absorbing heat during the day and releasing it at night.

a metal will be placed in fire and an electron will absorb enough energy to be promoted to a higher energy state. what do we call this higher energy state?

Answers

When a metal is placed in the fire and an electron absorbs enough energy to be promoted to a higher energy state, this higher energy state is referred to as the excited state.

An excited state is a state of a molecule or atom in which it has absorbed sufficient energy to move an electron from its current orbital to a higher orbital. This state is referred to as the excited state, and the electron that has been elevated to a higher energy level is said to be in an excited state.

The reason behind the electron's promotion to a higher energy state when a metal is placed in fire is that the heat causes the electrons to absorb energy, which causes them to move to a higher energy state. When electrons move to higher energy states, they release energy in the form of light, heat, or other radiation.
