Describe what happens on the molecular level when acetic acid dissolves in water.

Chemistry

Since most acetic acid molecules do not dissociate when a sample is dissolved in water, acetic acid and water molecule interactions are what determine how soluble a substance is. In its liquid state, water forms a network of hydrogen bonds among its molecules; when a material dissolves in water, this network of hydrogen bonds is broken.

<h3>What is acetic acid such a poor electrolyte?</h3>

Since acetic acid is a weak acid, only a small portion of the acetic acid molecules react to produce ethanoate and hydronium ions, shifting the equilibrium position substantially to the left. Aqueous acetic acid is a weak electrolyte as a result of the existence of these few ions.

<h3>Why does acetic acid have a low conductivity?</h3>

The majority ($> 99%) of the acetic acid molecules remain after dissolution, with only a very tiny portion deprotonating to form acetate anions. Only the latter are charged compounds, and as a result, only these increase the conductivity of the solution. They are few, and conductivity is low.

<h3>What makes acetic acid more potent than water?</h3>

The equilibrium shifts to the left and the concentration of hydrogen ions decreases when a strong acid is added to the buffer solution. A strong base is also added, which causes the equilibrium to move to the left and results in a smaller pH increase. Because of this, acetic acid is a better buffer than water.

Answer:

6. O₂ + Cu —> CuO

7. H₂ + Fe₂O₃ —> H₂O + Fe

8. O₂ + H₂ — > H₂O

9. H₂S + NaOH —> Na₂S + H₂O

10. Al + HCl —> H₂ + AlCl₃

Explanation:

6. Oxygen gas react with solid copper metal to form copper(II) oxide

Oxygen gas => O₂

Copper => Cu

copper(II) oxide => CuO

The equation is:

O₂ + Cu —> CuO

7. hydrogen gas and iron(III) oxide powder react to form liquid water and solid iron power

hydrogen gas => H₂

Iron(III) oxide => Fe₂O₃

Water => H₂O

Iron => Fe

The equation is:

H₂ + Fe₂O₃ —> H₂O + Fe

8. Oxygen gas react with hydrogen gas to form liquid water

Oxygen gas => O₂

hydrogen gas => H₂

Water => H₂O

The equation is:

O₂ + H₂ — > H₂O

9. Hydrogen sulphide gas is bubbled through a sodium hydroxide solution to produce sodium sulphide and liquid water

hydrogen sulphide => H₂S

sodium hydroxide => NaOH

Sodium sulphide => Na₂S

Water => H₂O

The equation is:

H₂S + NaOH —> Na₂S + H₂O

10. Hydrogen gas and aluminum chloride solutions are produced when solid aluminum react with hydrochloric acid

Aluminum => Al

Hydrochloric acid => HCl

hydrogen gas => H₂

Aluminum chloride => AlCl₃

The equation is:

Al + HCl —> H₂ + AlCl₃

47.0ml of a HBr solution were titrated with 37.5ml of a 0.215M LiOH solution to reach the equivalence point. what is the molarit
faltersainse [42]

Hello!

The molarity of the HBr solution is 0,172 M.

Why?

The neutralization reaction between LiOH and HBr is the following:

HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)

To solve this exercise, we are going to apply the common titration equation:

M1*V1=M2*V2

M1=\frac{M2*V2}{V1}= \frac{0,215 M * 37,5 mL}{47 mL}=0,172 M

Have a nice day!

An element has an atomic number of 18 and an atomic mass of 40. The number of neutrons in the nucleus of an atom of this element
Vikentia [17]

Answer: 22 neutrons

Explanation: 40 is the mass number = atomic mass = total number of protons and neutrons in atomic nucleus

18 is the number of protons in the nucleus of this atom

Then 40 - 18 = 22 neutrons

and this is Argon
