Question

ASSIGNMENT 1. Potassium hydrogen carbonate + hydrochloric acid--> 2. Potassium carbonate +hydrochloric acid--> 3. Zinc carbonate + sulphuric acid-->

Answer 1

1. The equations for the reactions occurring are: reaction 1: K2CO3(s) + 2HCl(aq) → 2KCl(aq) + CO2(g) + H2O(l) reaction 2: KHCO3(s) + HCl(aq) → KCl(aq) + CO2(g) + H2O(l) 2.

2. On adding hydrochloric acid to potassium carbonate, it vigorously produce carbon dioxide gas leaving aqueous solution of potassium chloride.

3. If zinc carbonate reacts with sulfuric acid, then the salt produced is zinc sulfate. When an alkali and an acid react the product is a salt solution. The particular salt produced depends upon which acid and which alkali reacted.

Answer 2

Answer:

Explanation:

Balance the equation potassium carbonate + water -----> potassium hydroxide + water + carbon dioxide
