How many moles of water (H₂O) are formed when the reaction is allowed to go to completion? Use equation for the question:
37.2 g of methane (CH4) are reacted with excess oxygen (02). The following combustion is allowed to go to completion. (Molar mass of CH4 = 16.0 g/mol)

Ch4(g) + 2O2(g) = CO2 (g) + 2H2O (I)

1.16 mol
2.33 mol
4.65 mol
298 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.

the answer your looking for is c).
