80 g of `H_(2)` is reacted with 80 g of `O_(2)` to form water. Find out the mass of water obtained. Which substance is the limiting reagent ?

Explanation

To solve the problem, we need to determine the mass of water produced when 80 g of H₂ reacts with 80 g of O₂, and identify the limiting reagent in the reaction.

### Step 1: Write the balanced chemical equation
The balanced chemical equation for the reaction between hydrogen and oxygen to form water is:

\[ 2 \text{H}_2 + \text{O}_2 \rightarrow 2 \text{H}_2\text{O} \]

### Step 2: Calculate the molar masses
