Sagot :
The complete part of this question is that we are told to write a balanced equation for the combustion reaction.
The balanced equation for the combustion
reaction of Ethanol we are given is;
C2H5OH (l) + 3O2 (g) = 3H20 (g) + 2CO2 + 1235
KJ of heat.
Now, we are told that Ethanol which is
liquid and has a chemical formula of C2H5OH
undergoes complete combustion to produce
Carbon (IV) Oxide gas which has a chemical
formula of CO2; water with a chemical formula of
H2O steam and releases heat of 1235 KJ of heat.
Now, when a substance undergoes
combustion, it means it reacts with oxygen.
Thus, we have the left side of the reaction which
is; C2H5OH (l) + O2 (g)
- Now in chemical reactions, the left hand side are the reactants while the right hand side are the products. Since we have the products as H2O, CO2 and the heat, Thus, our balanced equation will be;
C2H5OH (l) + 3O2 (g) = 3H20 (g) + 2CO2 + 1235 KJ of heat.
