Someone plz help me here are the photos, I need the last one

(6 mol)·(-393.5 kJ/mol) + (6 mol)·(-285.83 kJ/mol) - (1 mol)·(-1,273.02 kJ/mol) + (6 mol)·(0 kJ/mol)

Explanation:

Question; From the given options, the chemical reaction in the question is presented as follows;

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l), given that we have;

for C₆H₁₂O₆ = -1,273.02 kJ/mol

for O₂(g) = 0 kJ/mol

for CO₂(g) = -393.5 kJ/mol

for H₂O(l) = -285.83 kJ/mol

The heat or enthalpy of a reaction,  is given as follows;

Therefore, the equation which should be used to calculate , is given as follows;

= (6 mol)·(-393.5 kJ/mol) + (6 mol)·(-285.83 kJ/mol)

= (1 mol)·(-1,273.02 kJ/mol) + (6 mol)·(0 kJ/mol)

Therefore;

= (6 mol)·(-393.5 kJ/mol) + (6 mol)·(-285.83 kJ/mol) - (1 mol)·(-1,273.02 kJ/mol) + (6 mol)·(0 kJ/mol)

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
