In order to design an experiment to model exothermic reactions, a student places various levels of calcium chloride (0 grams, 2 grams, 4 grams, 6 grams, 8 grams, and 10 grams) into beakers with 100 ml of water. The temperature of the water taken before and after the calcium chloride is placed in the solution is recorded. What evidence would support the student's claim that the concentration of calcium chloride is directly related to the amount of energy in the reaction?

Willow Gregory · Answer 1

The evidence is the rise of the temperature

Explanation:

The concentration of the calcium chloride is directly related to the amount of energy because as the concentration of chloride is raised the temperature of the water will rise more dramatically and probably more rapidly, that means the reaction will hit higher temperatures in a short period of time.
