As you move from left to right on the periodic table, metallic character decreases.
The chemical equation for this combustion reaction is:
<span>C8H18 + O2
--> CO2 + H2O</span>
Balancing by adding whole number coefficients:
<span>2 C8H18 + 25
O2 --> 16 CO2
+ 18 H2O</span>
Including the phases:
<span>2 C8H18 (l) + 25 O2
(g) --> 16 CO2 (g) + 18 H2O (l)</span>
<span>where g is gas and l is liquid</span>
