Camryn Vaughn · Answer 1

An exothermic reaction is one that releases energy from the system to its surroundings, usually in the form of heat, but also in the form of light, electricity, or sound. Since the water gives off heat, the temperature of the water should be lower, so the answer might be B) The thermometer will show a decrease in temp.
