Assuming that all the energy given off in the reaction goes to heating up only the air in the house, determine the mass of methane required to heat the air in a house by 10.0∘c. assume each of the following: house dimensions are 35.0 m × 35.0 m × 3.2 m ; specific heat capacity of air is 30 j/k⋅mol; 1.00 mol of air occupies 22.4l for all temperatures concerned.

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.
