Explanation:

When two solutions are combined and the new solution becomes hot, it indicates a chemical reaction is occurring. Chemical reactions often involve energy - changes like heat release. Physical changes do not involve a change in the chemical composition and usually do not have significant heat - release. If the physical properties are the same, it's a physical change. Gas production and insolubility are also signs of chemical changes, but the heat generation in this case points to a chemical change.

Answer:

C. a chemical change is taking place
