Question

Sulphuric acid reacts with potassium carbonate to form potassium sulphate,
carbon dioxide and water
i. Write word equation for each of the chemical reactions above
ii. Write a balanced a chemical equation for each of the chemical reactions
in above.
Write a balanced chemical equation for the following reactions.
i. CaCO3 + HCl → CaCl2 + CO2 + H2O
ii. Mg + O2 → MgO
iii. NaOH + H2SO4→ Na2SO4 + H2O
iv. MgO + HCl → MgCl2 + H2O
v. H2SO4 + KOH → K2SO4 + H2O

Answer 1

Explanation:

1: potassium chloride+sulphuric acid--->potassium sulphate+corbon di oxide+water.

2:K2CO3 + H2SO4 →K2SO4 + CO2 + H2O.

Balanced equations:

1 . CaCO3+2HCl--->CaCl2+CO2+H2O.

2. 2Mg+O2--->2MgO.

3. 2NaOH+H2SO4--->Na2SO4+2H2O.

4. MgO+2HCl--->MgCl2+H2O.

5. H2SO4+2KOH--->K2SO4+2H2O.
