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?

Drag each tile to the correct box. the body monitors the levels of oxygen in the blood to regulate breathing. isabel is running in a marathon and is near the finish line. she feels out of breath. how will her nervous system work to generate a reaction? arrange the tiles in chronological order. isabel's breathing rate increases. sensory receptors in the arteries detect low oxygen levels. the brain sends signals through motor neurons. sensory neurons generate an impulse. the central nervous system relays an impulse to certain brain regions.
