If the H+ concentration in a certain tap-water sample is 2.6 × 10-7 M, what is the OH concentration? (Hint: find the pH and pOH first!!)

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.
