Complete and balance the following reactions :
`CH_2=CH_2+H_2 to` ………

Explanation

To complete and balance the reaction of ethene (CH₂=CH₂) with hydrogen (H₂), we follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced equation for the reaction is:
\[ \text{CH}_2=\text{CH}_2 + \text{H}_2 \rightarrow \text{C}_2\text{H}_6 \]

### Step 2: Identify the products
When ethene (CH₂=CH₂) reacts with hydrogen (H₂) in the presence of a catalyst (like nickel), it undergoes hydrogenation to form ethane (C₂H₆).
