Use the following balanced chemical equation C6H12 + 9 O2 > 6 CO2 + 6 H2O
How many moles of O2 can react with 1.75 mol of C6H12?

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
