the complete combustion of ethanol, c2h5oh(l), to form h2o(g) and co2(g) at constant pressure releases 1235 kj of heat per mole of c2h5oh.

Respuesta :

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.
