is the effect of hot and cold water on acid different?​

Answers

Answer 1

Answer:

When the acid is mixed with the water, an immediate chemical reaction takes place. The formation of carbon dioxide causes breakdown of the sample into finer particles.  

The heat in the Stomach rises up, causing esophageal reflux, chronic sinusitis, headaches, eye disorders and problems with the teeth. Furthermore, ingesting cold water creates moisture or “dampness.” Bacteria, candida, and parasites thrive in damp areas, especially in your stomach and uterus.

An ammonia solution has a pH of 8.25. What is its [OH-]?

Answers

pH + pOH = 14

If pH=8.25, then:

pOH = 14 - 8.25 = 5.75

pOH = -log[OH-]

5.75 = -log[OH-]

-5.75 = log[OH-]

10^(-5.75) = [OH-]

[OH-] = 0,0000017783

[OH-] = 1,78×10^(-6) mol/dm³

Which of the following is a challenge of prosthetic engineering that has been met through tissue engineering?

- Predicting failure
- Biocompatibility
- Strength
- Power

Answers

Answer:

Biocompatibility

Explanation:

I’m a genius and it’s the answer :D

Biocompatibility is a challenge of prosthetic engineering that has been met through tissue engineering. Hence, option B is correct.

What is Biocompatibility?

Biocompatible materials are used in medical devices, such as menstrual cups, stents, or ventilators.

A biocompatibility problem might happen when some of the materials are trapped in the patient's gingival sulcus.

Tissue engineering is an important field of regenerative medicine for tissue repair (after damaged caused by a disease or an accident, for example).

To offer this possibility, stem cells are important tools owing to their capacity to differentiate into a large number of cells according to the stimuli provided.

Hence, option B is correct.

Diazene, N2H2 (also known as diimine), is commonly used as a reagent for organic syntheses. Label each image with the type of
bond in diazene that it shows.

Answers

The first image shown at the left hand side is a pi bond. The other two images show sigma bonds.

In chemistry, a bond results from the overlap of atomic orbitals. This overlap may be end to end (sigma bond) or side by side (pi bond). Having said this, it is easier to decide whether the bonds in the image shown are sigma or bi bonds.

If we label the images; 1,2,3 from left to right, we can see that the overlap in image 1 is side by side. The electron density lies above and below the plane of the bond. This is a pi bond. In images 2 and 3, the overlap occurs in an end to end manner. This is a sigma bond.

It is used only for studying the properties of gases. It explains that substances with the same moles have the same mass.

Answers

Answer:

B) It allows chemists to deal with a large number of atoms.

Explanation:

On Edge 2022

The  statement  which best explains the purpose of using a mole in the measurement of matter is that it allows chemists to deal with a large number of atoms.

What is a mole?

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons .Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

A substance has a molar heat of combustion of -810.4 kj/mol. when 0.285 mol of the substance is burned in a calorimeter containing 8.60 kg of water, the increase in water temperature is:

Answers

Answer:

6.42 °C

Explanation:

Q = mcΔT

Q = energy gain/release (J)

m = mass (kg)

c = specific heat capacity (J/°C/kg)

ΔT = change in temperature (°C)

Qs = n(ΔH°c)

Qs = energy gained/released from substance (kJ)

n = moles (mol)

ΔH°c = molar heat of combustion (kJ/mol)

m = 8.60

n = 0.285

ΔH°c = -810.4

c (of water) = 4184

Qs = 0.285(-810.4)

Qs = -230.964 (or -230964 J)

Q = 230964

230964 = (8.60)(4184)ΔT

230964 = 35982.4(ΔT)

ΔT = 6.4188... °C → 6.42 °C

Your teacher asks you to prepare 500 mL of a 2.75 molar solution of NaCl for an upcoming
laboratory experiment. Write a step-by-step procedure describing how you would carry out
this task.

Answers

To prepare 500 mL of a 2.75 molar solution of NaCl, measure 80.44 g of NaCl, place it in a 500 mL volumetric flask and fill it with water to the mark.

We'll begin by calculating the number of mole of NaCl in the solution

Volume = 500 mL = 500 / 1000 = 0.5 L Molarity = 2.75 MMole of NaCl =?

Mole = Molarity x Volume

Mole of NaCl = 2.75 × 0.5

Mole of NaCl = 1.375 mole

Next, we shall determine the mass of 1.375 mole of NaCl.

Mole of NaCl = 1.375 mole Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol Mass of NaCl =?

Mass = mole × molar mass

Mass of NaCl = 1.375 × 58.5

Mass of NaCl = 80.44 g

Therefore, to prepare 500 mL of a 2.75 molar solution of NaCl, measure 80.44 g of NaCl, place it in a 500 mL volumetric flask and fill it with water to the mark.

A. KCL

C. PCL

I think it’s A and D but if it’s not both can you please explain why it’s one and not the other?

Answers

Answer:

Yes Both A) KCL and D) HCL are correct...

Answer:

It's only A

Explanation:

Potassium (K) is a metal and Chlorine (Cl) is a nonmetal, and ionic compounds are formed between metals and nonmetals. So KCl forms ionic bonds.

Hydrogen (H) and Chlorine (Cl) are both nonmetals, and only covalent bonds form between nonmetals. (Only exception is when its an acid, then it's ionic)

Also, the question indicated which "pair" and not "pairs" meaning that there is only one answer, and I'm more likely to go with A rather than D.
