calcium phosphate reacts with sulfuric acid to produce calcum sulfate and phosphoric acid. suppose the reaction is carried out starting with 123 g of calcum phosphate and 90.2 g of sulfuric acid. Which substance is the limiting reactant

Fine out your self ponk

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
