Question

please solve this chemistry Question​

Answer 1

Explanation:

Given -

• Word equation

To Find -

• Write balanced chemical equation

Now,

1) Calcium oxide + Carbon dioxide → Calcium carbonate

Solution :-

When calcium oxide reacts with carbon dioxide it forms calcium carbonate. (Combination reaction)

Chemical equation :-

CaO + CO2 → CaCO3 (Already balanced)

2) Magnesium + sulphuric acid → Magnesium sulphate + Hydrogen

Solution :-

When magnesium reacts with sulphuric acid it forms magnesium sulphate and hydrogen gas. (Displacement reaction)

Chemical equation :-

Mg + H2SO4 → MgSO4 + H2 (Already balanced)

3) Potassium nitrate → Potassium nitrite + Oxygen

Solution :-

When potassium nitrate is heated then it breaks down into potassium nitrite and oxygen gas. (Decomposition reaction)

Chemical equation :-

2KNO3 → 2KNO2 + O2
