Name the type of chemical reaction represented by the following equation:
(i) `CaO+H_(2)OrarrCa(OH)_(2)`
(ii) `3BaCl_(2)+Al_(2)(SO_(4))_(3)rarr2AlCl_(3)+3BaSO_(4)`
(iii) `2FeSO_(4)overset("Heat")rarrFe_(2)O_(3)+SO_(2)+SO_(3)`

Explanation

To identify the type of chemical reaction for each of the given equations, we will analyze them one by one.

### Step 1: Analyze the first equation
**Equation:** `CaO + H2O → Ca(OH)2`

- **Description:** In this reaction, calcium oxide (CaO) reacts with water (H2O) to form calcium hydroxide (Ca(OH)2).
- **Type of Reaction:** This is a **combination reaction** because two reactants are combining to form a single product.
