Answer
$C_{2}H_{4}$ + 3$O_{2}$ ${\longrightarrow}$ 2$CO_{2}$+ 2$H_{2}O$
Work Step by Step
$C_{2}H_{4}$ + $O_{2}$ ${\longrightarrow}$ $CO_{2}$+ $H_{2}O$
Before interpreting the equation, we balance by adding 2 before $CO_{2}$ and $H_{2}O$, and by adding 3 before O2.
$C_{2}H_{4}$ + 3$O_{2}$ ${\longrightarrow}$ 2$CO_{2}$+ 2$H_{2}O$
Molecular interpretation:
1 molecule $C_{2}H_{4}$ + 3 molecules $O_{2}$ ${\longrightarrow}$ 2 molecules $CO_{2}$+ 2 molecules $H_{2}O$
Molar interpretation:
1 mol $C_{2}H_{4}$ + 3 mol $O_{2}$ ${\longrightarrow}$ 2 mol $CO_{2}$+ 2 mol $H_{2}O$
Mass interpretation:
28.0 g $C_{2}H_{4}$ + 3 x 32.0 g $O_{2}$ ${\longrightarrow}$ 2 x 44.0g $CO_{2}$+ 2 x 18.0 g $H_{2}O$
