When hydrolith is treated with water it yields

Options

A. `H_(2)`
B. `H_(2)O_(2)`
C. NaH
D. `N_(2)`

Answer

To solve the question "When hydrolith is treated with water it yields," we will follow these steps:

### Step 1: Identify Hydrolith
Hydrolith is another name for Calcium Hydride (CaH₂).

### Step 2: Write the Reaction
When Calcium Hydride reacts with water, the chemical reaction can be represented as:
\[ \text{CaH}_2 + 2 \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 + \text{H}_2 \uparrow \]

### Step 3: Analyze the Products
From the reaction, we can see that the products formed are:
1. Calcium Hydroxide (Ca(OH)₂)
2. Hydrogen gas (H₂)

### Step 4: Conclusion
Thus, when hydrolith (Calcium Hydride) is treated with water, it yields Calcium Hydroxide and Hydrogen gas.

### Final Answer
The correct answer to the question is that it yields Hydrogen gas (H₂) and Calcium Hydroxide (Ca(OH)₂).
