Answer:
The CO2 Lewis structure has two double bonds going from carbon to the oxygen atoms. According to the octet rule, each oxygen atom needs to bond twice and the carbon atom needs to bond four times.
put 8 in front of the oxygen in the reactants side to make it 16 molecules then put a 5 in front of the co2 in the product side to balance the carbon atoms then put a 6 in front of the H20 on the product side this balances both the hydrogen and oxygen atoms here is a representation
C5H12(g)+8O2(g)=5CO2(g)+6H20
Liquidity metric is the other name
