Question

c. Give balanced equations for the following reactions: [5]
1. Hydrogen to ammonia using nitrogen.
2. Calcium carbonate to calcium oxide and carbon dioxide.
3. Zinc nitrate and sodium carbonate to form a precipitate and a soluble salt
4. Iron and copper sulphate.
5. Carbon dioxide and water to carbonic acid

Answer 1

Answer:

Explanation:

1) N2+3H---->2NH3

 nitrogen2+3hydrogen--------->2Ammonia

2)  CaCO3------->CaO + CO2

    calcium carbonate-------------> calcium oxide+ carbon dioxide

3) Zn(NO3)2 + Na2CO3  ------------->ZnCO3 + NaNO3

 zinc nitrate+ sodium carbonate------------->Zinc Carbonate+ sodium nitrate

4) Fe + Cu2 —-->Fe2 + Cu

   iron+ copper-----------> iron+copper

5) H2CO3----------->CO2+H2O

Carbonic acid-----------> carbondioxide+ water
