Part one: calculate the molarity of ba2+ in an aqueous solution that contains 1.7 g of ba(oh)2 in 0.75 l of solution.
answer in units of mol/l.
part two: what is the molarity of h3o+?
answer in units of mol/l.

answer: find it ur self

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.
