Answer: Option (a) is the correct answer.

Explanation:

Ionic compounds are the compounds which are formed by transfer of electrons.

Atoms of ionic compounds are attached together by strong force of attraction due to opposite charges on its atoms.

Also, ionic compounds readily dissociate into ions.

Therefore, we can conclude that ionic type of compound dissociates.

Hydrobromic acid (HBr) and sodium hydroxide (NaOH) combine in a neutralization reaction to form water and a salt. Which of the f
Debora [2.8K]

Answer:

The salt that is produces is NaBr.

Explanation:

When an acid react with base it form the salt and  water. The reaction is also called neutralization reaction because both neutralize each other.

In neutralization reaction equal amount of acid and base react to neutralize each other and equal amount of water and salt are formed. When pH does not reach to 7 its means there is less amount of one of reactant which is not fully neutralize.

Neutralization reactions are also used as first aid. For example when someone is dealing with HCl for cleaning purpose of toilet and get touched. It is advised to neutralize it with soap, milk or egg white.

Example:

Hydrobromic acid when react with the sodium hydroxide, a salt sodium bromide and water are formed.

Chemical equation:

HBr + NaOH → NaBr + H₂O

Properties of Sodium Bromide:

  • It is present in the form of colorless crystals.
  • It is also present in powder form.
  • It is very toxic.
  • It is soluble in water.
  • It is bitter in taste and also odorless.

How do the percent compositions for C3H6 and C4H7 compare?
mariarad [96]

A. They are the same

<h3>Further explanation</h3>

Given

C3H6 and C4H8

Required

The percent compositions

Solution

  • C₃H₆(MW = 42 g/mol)

%C = 3.12/42 x 100% = 85.71%

%H = 6.1/42 x 1005 = 14.29%

C₄H₈(MW=56 g/mol)

%C = 4.12/56 x 100% = 85.71%

%H = 8.1/56 x 100%=14.29%

So they are the same, because mol ratio of C and H in both compounds is the same, 1: 2

What is the concentration of the hydroxide ion? Given that the concentration of the hydronium ion is 2.3 X 10^-7 M
professor190 [17]

Answer:

4.35 * 10^-8 M

Explanation:

Since the concentration of the hydronium ion= 2.3 X 10^-7 M

And we know that;

[H3O^+] [OH^-] = 1 * 10^-14

[H3O^+]  = concentration of the hydronium ion

[OH^-] = concentration of the hydroxide ion

So;

[OH^-] =1 * 10^-14/[ H3O^+]

But [H3O^+] = 2.3 X 10^-7 M

[OH^-] = 1 * 10^-14/2.3 X 10^-7

[OH^-] = 4.35 * 10^-8 M
