which is the more stable part of this system, the reactants or the products?

Question

also the entalpy of combustions of acetylene gas is -1301.1kJ/mol of C2H2
write a balanced thermochemical equation for the complete combustion of C2H2

Answer 1

In this reaction, the products are more stable because the combustion happens with the release of a lot of energy.

When you combust anything with C's and H's, you are going to react it with O2 to form just CO2 and H2O.

Given that, can you write the balanced equation?

Answer 2

C2H2 + 5/2O2 ----> 2CO2+ H2O
The products are more stable because exothermic reactions release energy because there is more energy used in beaking bonds than forming bonds
