A solution may contain one or more of the Group I cations. A white precipitate forms when 6 M HCl is added to the solution. The precipitate is insoluble in hot water. The precipitate is then found to be completely soluble in 6M NHIndicate whether each of the following cations is present, undetermined, or absent.

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.
