Question

The dissolution of calcium chloride in water is given by the following equation:CaCl2(s) + 2H2O → Ca(OH)2(aq) + 2HCl(g) + heatHow would an energy graph of this reaction appear?(1 point)ResponsesThe reactants and products would appear at a low energy state.The reactants and products would appear at a low energy state.The reactants would appear at a higher energy state than the products.The reactants would appear at a higher energy state than the products.The reactants and products would appear at a high energy state.The reactants and products would appear at a high energy state.The reactants would appear at a lower energy state than the products.

Answer 1

The reaction you've described involves the dissolution of calcium chloride (CaCl2) in water, which is an exothermic process. In such a reaction, heat is released, indicating that the products have lower energy than the reactants. Therefore, an energy graph for this reaction would show the reactants at a higher energy state than the products.

The correct response is:
**The reactants would appear at a higher energy state than the products.**
