Question

Transfer the following statements into Chemical equations and then balance

them.

a) Hydrogen gas combines with nitrogen to form ammonia.

b) Potassium metal reacts with water to give potassium hydroxide and

hydrogen gas​

Answer 1

Answer:

(a) Hydrogen gas combines with nitrogen to form ammonia.

H

(g)→NH

3

The balanced equation for this reaction can be written as:

3H

(b) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.

K+H

2

O→KOH+H

The balanced equation for this reaction can be written as:

2K+2H
