3.00 L of CH4 is known to contain 0.650 moles at a certain temperature and pressure. if the volume of a chamber of CH4 increases from 7.00 L to 8.20 L how many moles of CH4 were added? Assume temperature and pressure stayed constant. moles

am i too late?

explanation:

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.

they are all solids.
