Answer:

Here is your answer dear friend

Explanation:

1. Decomposition reaction:

CaCO3 → CaO + CO2

• This is a decomposition reaction because a single reactant ( CaCO3) breaks down into two or more simpler products (CaO and CO2).

2. Neutralization reaction: CaO + H2O→ Ca(OH)2

• This is a neutralization reaction because an oxide reacts with water (H2O) to form a hydroxide (Ca(OH)2), which is a common characteristic of neutralization reactions.

3. Decomposition reaction:

2FeSO4→ Fe2O3 + SO2 + SO3

• This is a decomposition reaction where a complex compound ( 2FeSO4) breaks down into simpler substances (Fe2O3, SO2, and SO3).

4. Decomposition reaction:

NH4Cl NH3 + HCl

• This is a decomposition reaction where NH4Cl breaks down into ammonia (NH3) and hydrogen chloride (HCI).

5. Combination reaction: 2Ca + O2 → 2CaO

• This is a combination reaction as two or more substances (2Ca and O2) combine to form a single product (2CaO).
