8 0

1) The first reactant is incomplete.


2) The reaction is a combustion reaction and it is easy to infere that it is the combustion of the alkane with 3 carbons.


3) The general chemical formula of the alkanes is

               C_nH_{2n+2}


4) Hence the equation is:


C_3H_8+O_2->H_2O+CO_2


5) The name of the alkane is propane, so the word equation is:


            propane + oxygen → carbon dioxide + water


6) The equation is unbalanced. This is the balanced equation:


            C_3H_8+5O_2->4H_2O+3CO_2


7) It is, as the combustion of any hydrocarbon, a redox (reduction-oxidation) reaction, where the carbon is oxidized and the oxygen is reduced.


8) This kind of reactions release a lot of energy.
