Answer

Explanation:

Step1: Write the chemical equation

The reaction is $H_2 + Cl_2\rightarrow 2HCl$.

Step2: Analyze atom - conservation

In $H_2$, there are 2 H - atoms; in $Cl_2$, there are 2 Cl - atoms. In HCl, each molecule has 1 H - atom and 1 Cl - atom. To account for 2 H - atoms and 2 Cl - atoms in the products, we need 2 molecules of HCl.
