Sati [7]

Answer:

Write a chemical equation for KOH(aq) showing how it is an acid or a base according to the Arrhenius definition.

Express your answer as a chemical equation. Identify all of the phases in your answer.

Write a chemical equation for NH4+(aq) showing how it is an acid or a base according to the Arrhenius definition.

Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation:

According to this theory, an acid is a substance that is a proton donor when the substance is dissolved in water.

The base is the one that gives OH- ions when dissolved in water.

KOH(aq) is a base.

Because it releases OH- ions when dissolved in water.

KOH(aq)->K^+(aq)+OH^-(aq)

The ammonium ion is an acid.

It can donate a proton when dissolved in water.

NH_4^+(aq)->NH_3(aq)+H^+(aq)

How many neutrons and protons does a neutral atom of sodium with an atomic mass number of 23 have? A. 22 neutrons; 11 protons B.
atroni [7]
In order to find out how many protons a sodium atom has, you have to look at the periodic table. Sodium is Na on the periodic table and you look for the number on the top of the symbol and you can see that it has 11 protons. To find out how many neutrons, you have to subtract 11 from the mass number, which is 23. 23-11 = 12.

12 neutrons; 11 protons
