what is the relative rate of diffusion between oxygen gas and carbon dioxide? oxygen gas is x the rate of carbon dioxide

Answers

Answer 1

The relative rate of diffusion between oxygen gas and carbon dioxide is 1:0.8. Diffusion is the process of spreading out or scattering a substance, particularly molecules that move randomly inside a fluid or gas.

When substances are dispersed, they shift from areas of high concentration to areas of low concentration. The rate of diffusion determines how quickly or slowly a substance will spread. In a gas or liquid, the molecules diffuse more quickly when the temperature is high.

The ratio of two molecules' diffusion rates is known as the relative rate of diffusion. The relative rate of diffusion can be determined using Graham's law of diffusion. According to this law, the rate of diffusion of a gas is inversely proportional to the square root of its molecular weight.

The relative rate of diffusion of two gases can be determined using this law.Let's look at oxygen gas and carbon dioxide now. The molecular weight of oxygen gas is 32 g/mol, while that of carbon dioxide is 44 g/mol.

The relative rate of diffusion can be determined using Graham's law of diffusion:

Relative rate of diffusion of oxygen gas:√(44/32)

Relative rate of diffusion of oxygen gas: 1.2

Relative rate of diffusion of carbon dioxide:√(32/44)

Relative rate of diffusion of carbon dioxide: 0.8

Therefore, the relative rate of diffusion between oxygen gas and carbon dioxide is 1:0.8.

predict which of the following 0.1m solutions would have the lowest freezing point: mg(cl)2, catechin, or sucrose. explain your reasoning.

Answers

The freezing point of a 0.1m solution is determined by its solute concentration, and the type of solute affects the freezing point and it will be Catechin.

The lowest freezing point will be found in the solution with the lowest solute concentration.

In this case, catechin has the lowest solute concentration of 0.001 mol/L, so it will have the lowest freezing point.

The freezing point of a solution is also affected by the type of solute present.

Magnesium chloride (MgCl2) and sucrose both have high molecular weights, and therefore will decrease the freezing point more than catechin. Therefore, catechin will still have the lowest freezing point.

The freezing point of a solution can also be affected by the presence of electrolytes.

Magnesium chloride is an electrolyte, which means it will dissociate in water and lower the freezing point more than catechin or sucrose. Therefore, catechin still has the lowest freezing point.

In summary, catechin has the lowest freezing point of the three solutions (MgCl2, catechin, and sucrose) because it has the lowest solute concentration and does not contain any electrolytes.

explain why only one peak is present (either the anodic or cathodic peak) in a cyclic voltammogram of an irreversible electrochemical reaction.

Answers

In a cyclic voltammogram of an irreversible electrochemical reaction, only one peak is present (either anodic or cathodic) due to the limited reversibility of the reaction.

An irreversible reaction cannot be completely reversed so when the potential of the reaction is increased, the reaction will proceed in the same direction, leading to the formation of a single peak.

The peak represents the forward reaction, either the oxidation or reduction of the species in the reaction.

The magnitude of the peak depends on the rate of the forward reaction and the degree of reversibility of the reaction.

When the potential of the reaction is increased, the reaction will move further in the same direction, and the peak will become more prominent.

The peak will reach a maximum size when the reaction reaches its equilibrium potential, which occurs when the rate of the forward and reverse reactions are equal.

The magnitude of the peak also depends on the rate of diffusion of the species in the reaction. The peak will be smaller when the rate of diffusion is slow, and it will be larger when the rate of diffusion is fast.

The shape of the peak will depend on the degree of reversibility of the reaction, with more symmetrical peaks for reversible reactions and more asymmetrical peaks for irreversible reactions.

Only one peak is present in a cyclic voltammogram of an irreversible electrochemical reaction due to the limited reversibility of the reaction.

The magnitude of the peak is determined by the rate of the forward reaction, the rate of diffusion of the species, and the degree of reversibility of the reaction.

you have a stock solution of 0.6 molar sucrose, and want to prepare 3 ml of 0.24 molar sucrose solution. what are the correct amounts of 0.6 m sucrose and water that you will need to use?

Answers

Answer : To prepare 3 mL of 0.24 M sucrose solution from a stock solution of 0.6 M sucrose, 1.2 mL of the stock solution and 1.8 mL of water should be used.

The amount of 0.6 Molar sucrose needed to prepare 3 mL of 0.24 Molar sucrose solution, as well as the volume of water required, can be calculated using the M1V1 = M2V2 formula. Where M1 is the molarity of the stock solution, V1 is the volume of the stock solution required, M2 is the desired molarity of the solution to be prepared, and V2 is the volume of the solution to be prepared.


Given that the stock solution of sucrose is 0.6 M, and we need to prepare 3 mL of a 0.24 M solution, we can use the formula:
0.6 M x V1 = 0.24 M x 3 mL Solving for V1:
V1 = (0.24 M x 3 mL)/0.6 M
V1 = 1.2 mL


This means that 1.2 mL of the stock solution of 0.6 M sucrose is required to prepare 3 mL of 0.24 M sucrose solution.
The volume of water required can be calculated by subtracting the volume of the stock solution from the total volume of the solution to be prepared: Volume of water = 3 mL - 1.2 mL and Volume of water = 1.8 mL

how is the elimination reaction different from the substitution reaction? how do we determine which one will happen and when? is there an example that breaks the rule one way or the other?

Answers

The elimination reaction is different from the substitution reaction because in the elimination reaction, two substituents are removed from a molecule to form a double bond or a ring.

In contrast, substitution reactions involve one substituent being replaced by another.In order to determine whether an elimination or substitution reaction will occur, the nature of the reactants and reaction conditions must be considered.

Factors such as the presence of a strong base, the leaving group ability of the substituent, and steric hindrance can all influence the outcome of a reaction.

For example, if a primary alkyl halide is reacted with a strong base such as sodium hydroxide in a polar solvent, an elimination reaction will likely occur due to the poor leaving group ability of the primary alkyl halide.

However, if a secondary or tertiary alkyl halide is reacted under the same conditions, a substitution reaction will likely occur due to the increased stability of the carbocation intermediate.There are exceptions to these general rules, such as the reaction between 2-methyl-2-butanol and hydrogen bromide.

In this case, the reaction can proceed through either an elimination or substitution pathway depending on the reaction conditions. Overall, the outcome of a reaction depends on a variety of factors and must be analyzed on a case-by-case basis.

which of the following should have the greatest molar entropy at 298k? group of answer choices h2o(l) nacl(aq) ch4 (g) nacl(s)

Answers

The species that should have the highest molar entropy at 298 K is CH4(g). The correct option is CH4.

Entropy is a measure of the amount of disorder or randomness in a system. In other words, it is a measure of the number of ways a system can be arranged while maintaining its energy state. It is represented by the symbol S.

The entropy of a pure crystalline substance is zero at absolute zero temperature because it has a well-defined, ordered, and rigid structure.

As temperature increases, the entropy of the substance increases because the molecules of the substance move more randomly and are distributed over a larger volume.

Entropy is highest for gases, followed by liquids and then solids. Molar entropy is a measure of the entropy of a substance per mole of the substance.

Molar entropy (S) is given by the equation:

S = ΔS/n

Where ΔS is the change in entropy and n is the number of moles of substance. At standard temperature and pressure, the molar entropy of a substance is represented by Sº.

The entropy of the given species at 298 K is as follows:

H2O(l)Sº = 69.9 J/mol KNaCl(aq)Sº = 72.1 J/mol KCH4(g)Sº = 186.3 J/mol KNaCl(s)Sº = 72.1 J/mol K

if 4.36 mol of potassium phosphate react, how many grams of barium phosphate are produced?

If 39.5 g AlCl3 is produced, how many grams of HCl was used in the reaction?

Answers

Answer:

400.87g of barium phosphate and 32.4g of HCL

Explanation:

The balanced chemical equation for the reaction between potassium phosphate and barium nitrate is:

3 K3PO4 + 4 Ba(NO3)2 → 12 KNO3 + Ba3(PO4)2

According to the stoichiometry of the equation, for every 3 moles of potassium phosphate, 1 mole of barium phosphate is produced. Therefore:

1 mol Ba3(PO4)2 = 3 mol K3PO4

To convert the given quantity of potassium phosphate to moles, we can use its molar mass:

4.36 mol K3PO4 = 4.36 mol × 212.27 g/mol = 925.5912 g

Now we can use the stoichiometry to calculate the amount of barium phosphate produced:

1 mol Ba3(PO4)2 = 3 mol K3PO4

1 mol Ba3(PO4)2 = 3/4 mol Ba(NO3)2 (from the balanced equation)

Therefore, the amount of barium phosphate produced is:

4.36 mol K3PO4 × 1 mol Ba3(PO4)2 / 3 mol K3PO4 × 4 mol Ba(NO3)2 / 3 mol Ba3(PO4)2 × 601.93 g/mol Ba3(PO4)2 = 400.87 g

Therefore, 400.87 grams of barium phosphate are produced.

We need to know the balanced chemical equation for the reaction in order to determine the stoichiometry of the reactants and products. Let's assume that the reaction is:

2 Al + 6 HCl → 2 AlCl3 + 3 H2

This equation tells us that 6 moles of HCl are required to produce 2 moles of AlCl3. The molar mass of AlCl3 is:

1 Al atom × 26.98 g/mol + 3 Cl atoms × 35.45 g/mol = 133.34 g/mol

Therefore, 39.5 g of AlCl3 represents:

39.5 g ÷ 133.34 g/mol = 0.296 moles of AlCl3

Since the reaction produces 2 moles of AlCl3 for every 6 moles of HCl, we can use a ratio to find the number of moles of HCl required:

0.296 moles AlCl3 × (6 moles HCl / 2 moles AlCl3) = 0.888 moles HCl

Finally, we can convert the number of moles of HCl to grams:

0.888 moles HCl × 36.46 g/mol = 32.4 g HCl

Therefore, 32.4 g of HCl was used in the reaction.

Answers

According to the second law of Faraday, the oxidation number of gold ions is +3.

What is the second law of Faraday?

The second law of Faraday is also known as Faraday's law of electrolysis. According to this, the quantity of a substance that is deposited or released during electrolysis is directly proportional to the amount of electric charge that is transported through the electrolyte.

Given information,

Mass of silver (Ag) deposited = 0.732 g

Mass of gold (Au) deposited = 0.446 g

According to this law,

Weight of Ag/Equivalent weight of Ag = Weight of Au/Equivalent weight of Au

0.732/108 = 0.446/196.96 × valency

Since the equivalent weight of Ag is 108g and the equivalent weight of Au is 196.96g.

0.0067 = 0.0022  × valency

This results in one element becoming a cation (a positively charged ion) and the other element becoming an anion (a negatively charged ion). The attraction between the opposite charges holds the two ions together in a crystal lattice, forming an ionic bond.

For example, in the formation of sodium chloride (NaCl), sodium donates one electron to chlorine, which accepts the electron, forming Na+ and Cl- ions. The attraction between the Na+ and Cl- ions forms the ionic bond in NaCl.

how many electrons does cl want to gain? hint: how many are gained to form a stable noble gas electron configuration, ns2 np6 (octet rule)?

Answers

Chlorine (Cl) is a nonmetal, meaning it has the tendency to gain electrons to achieve the electron configuration of a noble gas. The noble gas electron configuration of the nearest noble gas, argon (Ar), is 1s2 2s2 2p6 3s2 3p6, with a total of 18 electrons.

Chlorine has 7 valence electrons, meaning it needs 1 more electron to achieve a stable noble gas electron configuration. Therefore, chlorine wants to gain 1 electron to achieve a stable noble gas configuration.

In terms of bonding, chlorine can either gain 1 electron to form an anion with a 1- charge or it can share electrons with another atom to form a covalent bond. Chlorine most commonly forms a single covalent bond with another atom, such as hydrogen, to form hydrogen chloride (HCl). In this case, both atoms share electrons to form a stable molecule.

which solution has the highest vapor pressure? 20.0 g of glucose in 100.0 ml of water 20.0 g of sucrose in 100.0 ml of water 10.0 g of potassium acetate in 100.0 ml of water

Answers

The solution that has the highest vapor pressure is the one with the lowest boiling point. The lower the boiling point, the higher the vapor pressure.

What is Vapor Pressure?

Vapor pressure is the pressure exerted by the vapor of a substance in equilibrium with its liquid or solid phase. When the rate of evaporation and the rate of condensation is equal, equilibrium occurs. At a particular temperature, each liquid has a distinct vapor pressure that is directly proportional to its temperature. A liquid with a low boiling point has a higher vapor pressure than one with a high boiling point.

The glucose and sucrose solutions are both nonvolatile solutes, whereas potassium acetate is a volatile solute. As a result, the potassium acetate solution has a higher vapor pressure than either the glucose or sucrose solutions. The answer is option C.10.0 g of potassium acetate in 100.0 ml of water.

Calculate the molar mass for SnCL4

Answers

Answer:
To calculate the molar mass of SnCl4, we need to add the atomic masses of one tin (Sn) atom and four chlorine (Cl) atoms, each multiplied by their respective coefficients in the formula.

The atomic mass of Sn is 118.71 g/mol, and the atomic mass of Cl is 35.45 g/mol.

Therefore, the molar mass of SnCl4 can be calculated as follows:

Molar mass of SnCl4 = (1 × atomic mass of Sn) + (4 × atomic mass of Cl)

= (1 × 118.71 g/mol) + (4 × 35.45 g/mol)

= 118.71 g/mol + 141.80 g/mol

= 260.51 g/mol

So the molar mass of SnCl4 is 260.51 g/mol.

Answers

The electron configuration of valence electrons of carbon before and after sp hybridization are shown below:Before hybridization: 2s2 2p2After hybridization: sp2 2p2The orbital diagram before sp hybridization shows two electrons in the 2s orbital and two electrons in each of the 2p orbitals. After hybridization, the 2s orbital mixes with one of the 2p

orbitals to form two sp hybrid orbitals. These sp hybrid orbitals are oriented at 180° to each other, which allows maximum overlap with two 2p orbitals of the carbon atom. The remaining 2p orbital remains unhybridized and

unchanged. Therefore, the hybridized orbitals contain only one electron each and the unhybridized 2p orbital has two electrons.The boxes with arrows in the orbital diagram represent the orbitals and their electrons. The label "2s" is

dragged to the box representing the 2s orbital before hybridization. Similarly, the labels "2p" and "sp" are dragged to the boxes representing the unhybridized and hybridized orbitals after hybridization, respectively. The label "2p" is also dragged to the unhybridized 2p orbital after hybridization.
