Answer
2$H_{2}S$+ 3$O_{2}$ ${\longrightarrow}$ 2$SO_{2}$ + 2$H_{2}O$
Work Step by Step
$H_{2}S$+ $O_{2}$ ${\longrightarrow}$ $SO_{2}$ + $H_{2}O$
Before interpreting the equation, we balance by adding 2 before $H_{2}S$, $SO_{2}$ and $H_{2}O$, and by adding 3 before $O_{2}$.
2$H_{2}S$+ 3$O_{2}$ ${\longrightarrow}$ 2$SO_{2}$ + 2$H_{2}O$
Molecular interpretation:
2 molecules $H_{2}S$+ 3 molecules $O_{2}$ ${\longrightarrow}$ 2 molecules $SO_{2}$ + 2 molecules $H_{2}O$
Molar interpretation:
2 mol $H_{2}S$+ 3 mol $O_{2}$ ${\longrightarrow}$ 2 mol $SO_{2}$ + 2 mol $H_{2}O$
Mass interpretation:
2 x 34.0g $H_{2}S$+ 3 x 16.0 g $O_{2}$ ${\longrightarrow}$ 2 x 64.0g $SO_{2}$ + 2 x 18.0g $H_{2}O$
