Question

10. Identify the type of reaction as combination, decomposition,
displacement and double displacements
Fe2O3 + 2AL > Al2O3 + 2 Fe
(ii) ZnCO3 ----> ZnO + CO2
N2 + 3H2 -----2NH3
(iv) NaBr + AgNO3 ----- → AgBr + NaNO3​

Answer 1

Explanation:

2 KNO 3 (aq) → 2 KNO 2 (aq) + O 2 (g) KNO 3 is an oxidizing agent, KNO 3 is a reducing agent. This is a gas evolution reaction, O 2 is the formed gas.

Answer 2

Answer:

1) displacement reaction

2) decomposition

3) combination

4)double displacement
