Methane combusts with oxygen through the following reaction:
CH4 + 2O2 -> 2H2O
how many grams of carbon dioxide are produced when 16 g of methane and 48 g of oxygen gas combust?
molar mass of CH4 = 16 g
molar mass of O2 = 32 g
molar mass of CO2 = 44 g

the correct answer is boyle

*tilts head* sounds more like a statement

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.
