<u>538.73 g</u> is the mass of 5.85 mol of glycerol (C₃H₈O₃)

<h3>What is glycerol?</h3>

Glycerol is a simple polyol chemical, usually known as glycerine in British English and glycerin in American English. It is a sweet-tasting, colourless, odourless, viscous liquid that is non-toxic. Glycerides, a class of lipids, contain the glycerol backbone.

It is frequently utilised in FDA-approved wound and burn therapies due to its antibacterial and antiviral characteristics. On the other hand, it can also serve as a medium for bacterial cultivation. It can be used as a reliable indicator of liver illness.

Additionally, it is employed temporarily in the food sector as a sweetener and in drug formulations as a humectant. Glycerol is hygroscopic in nature and miscible with water due to its three primary hydroxyl groups.

Complete the sentences to explain what’s happening at different portions of the heating curve.

Neporo4naja [7]

Particles of the substance have the most kinetic energy when the substance is(a)1. A gas. The part of the graph that represents where the substance has the least amount of potential energy is labeled(b)1. Solid.

Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy. During freezing, a substance loses a lot of potential energy so solid has the least potential energy.

An undergraduate weighed out 20grams of sodium hydroxide pellets. If Na =23, O = 16 andH = 1, What is the mole of this sodium hy

tatuchka [14]

The answer would be .5 mols because you take the total amount of grams, which is 20, and you had up the molar mass of sodium hydroxide, which would be 40. After you have this you would set this up as a stochiometry equation. With 1 mol on top you dived 20/40 to cancel out your grams. This leaves you with .5 mols

A solution is prepared by dissolving 0.23 mol of chloroacetic acid and 0.27 mol of sodium chloroacetate in water sufficient to y

Sergio [31]

Answer:

c. chloroacetate ion

Explanation:

The chloroacetic acid, ClCH₂CO₂H, is a weak acid with Ka = 1.36x10⁻³. When this weak acid is in solution with its conjugate base, ClCH₂CO₂⁻ (From sodium chloroacetate) a buffer is produced. The addition of a strong acid as the HCl produce the following reaction

HCl + ClCH₂CO₂⁻ → ClCH₂CO₂H + Cl⁻.

Where the acid reacts with the chloroacetate ion to produce more chloroacetic acid

That means, the HCl reacts with the chloroacetate ion present in the buffer solution

Right answer is:

<h3>c. chloroacetate ion</h3>
