Answer
$H_{2}$ + $Cl_{2}$ ${\longrightarrow}$ 2 HCl
Work Step by Step
$H_{2}$ + $Cl_{2}$ ${\longrightarrow}$ HCl
To balance this chemical reaction, add 2 before HCl.
$H_{2}$ + $Cl_{2}$ ${\longrightarrow}$ 2 HCl
Molecular interpretation:
1 molecule $H_{2}$ + 1 molecule $Cl_{2}$ ${\longrightarrow}$ 2 molecules HCl
Molar interpretation:
1 mol $H_{2}$ + 1 mol $Cl_{2}$ ${\longrightarrow}$ 2 mol HCl
Mass interpretation:
2.02 g $H_{2}$ + 70.9 g $Cl_{2}$ ${\longrightarrow}$ 2 x 36.5 g HCl
