How many grams of chlorine are required to completely react with 0.650 g of hydrogen to yield hydrogen chloride ? Also calculate the amount of HCI formed.

Explanation

To solve the problem of how many grams of chlorine are required to completely react with 0.650 g of hydrogen to yield hydrogen chloride (HCl), and to calculate the amount of HCl formed, we will follow these steps:

### Step 1: Write the balanced chemical equation.
The balanced equation for the reaction between hydrogen and chlorine is:
\[ \text{H}_2 + \text{Cl}_2 \rightarrow 2 \text{HCl} \]

### Step 2: Determine the molar masses.
- Molar mass of hydrogen (H₂) = 2 g/mol
