Which contains more atoms, 1.00 mol h2o2 or 1.00 mol c2h6? explain.

1.00 mol C₂H₆

Explanation:

1 mole of C₂H₆ has 2 moles of C atoms and 6 moles of H atoms.

1 mole of H₂O has 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

6+2= 8,    2+1= 3

8 is bigger.

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.
