Calcium carbide reacts with water to produce

Options

A. methane
B. carbon dioxide
C. acetylene
D. carbohydrate

Explanation

To solve the question of what products are formed when calcium carbide reacts with water, we can follow these steps:

### Step 1: Identify the Reactants
The reactant in this reaction is calcium carbide, which has the chemical formula \( \text{CaC}_2 \).

### Step 2: Write the Reaction
When calcium carbide reacts with water, the reaction can be represented as:
\[ \text{CaC}_2 + 2 \text{H}_2\text{O} \rightarrow \text{C}_2\text{H}_2 + \text{Ca(OH)}_2 \]

### Step 3: Identify the Products
From the reaction, we can see that the products formed are:
1. Acetylene (\( \text{C}_2\text{H}_2 \)), which is also known as ethyne.
2. Calcium hydroxide (\( \text{Ca(OH)}_2 \)).

### Step 4: Conclusion
Thus, the products of the reaction between calcium carbide and water are acetylene and calcium hydroxide.

### Final Answer
The correct answer is that calcium carbide reacts with water to produce acetylene and calcium hydroxide.
