Question

consider the equations.
h₂ → 2h
c₂h₄ + h → c₂h₅
c₂h₅ + h → c₂h₆
when these equations are added together, what will the overall equation be? assume that no equations need to be reversed.
c₂h₄ + c₂h₅ + h₂ → c₂h₅ + c₂h₆
c₂h₄ + h₂ → c₂h₆

Explanation:

Step1: Write down the given equations

$H_2
ightarrow 2H$
$C_2H_4 + H
ightarrow C_2H_5$
$C_2H_5 + H
ightarrow C_2H_6$

Step2: Add the equations together

On the left - hand side, we have $H_2+C_2H_4 + H+C_2H_5 + H$. On the right - hand side, we have $2H+C_2H_5 + C_2H_6$.

Step3: Cancel out common terms

The $H$ atoms and $C_2H_5$ terms cancel out. The $2H$ on the right and the two $H$ terms on the left ($H + H$) cancel, and the $C_2H_5$ on both sides cancels. So the overall equation is $C_2H_4+H_2
ightarrow C_2H_6$.

Answer:

$C_2H_4 + H_2
ightarrow C_2H_6$
