Explanation:
The unbalanced combustion reaction of the oxidation of propane is shown below as:-
On the left hand side,
There are 3 carbon atoms and 8 hydrogen atoms and 2 oxygen atoms
On the right hand side,
There are 1 carbon atom and 2 hydrogen atoms and 3 oxygen atoms
Thus,
Right side, must be multiplied by 3 and
by 4 so to balance carbon and hydrogen.
Left side, is multiplied by 5 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the carbon dioxide in the balanced equation - 3</u>
