Answer 12

An alkaline solution

Question 13

What happens when ammonia reacts with nitric acid?

Answer 13

You get a neutral salt - ammonium nitrate

Question 14

What is the symbol and word equation for the reaction between ammonia and nitric acid?

Answer 14

NH₃ (aq) + HNO₃ (aq) -> NH₄NO₃ (aq)

Ammonia + Nitric acid -> Ammonium nitrate (NO WATER!!!!)

Question 15

Why is Ammonium nitrate a good fertiliser?

Answer 15

It has nitrogen from 2 sources, the ammonia and the nitric acid. Plants need nitrogen to make proteins
