If you use about 4.5 x 1023 atoms of carbon in your pencil as you complete this assignment, how many moles of carbon do you use?

u i forgot the answer?

i would say b

explanation:

but i think i would need more information than that

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.
