Jeffe is explaining dimensional analysis to a friend. he says that dimensional analysis can be used to convert between units. what is needed for this conversion?

An equality that tells how much of one unit is equal to another unit

the volume increases

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.
