Chemical Reactions: Types of Reactions

self check iconSelf-check: Endothermic and Exothermic Reactions

Complete the self-check activity by looking at the prompts below, thinking about each one, and then clicking on the arrows to review the explanation.

Think and Click What is the difference between an endothermic and an exothermic reaction?
Think and Click In your lab assignment, why did the jars change temperature after each reaction took place?
Think and Click Based on your lab results, what can you say about heat and the reaction of magnesium sulfate (Epsom salts) with water?
Think and Click Consider the photosynthesis reaction. Green plants take carbon dioxide and water from the environment and produce glucose (sugar), which people and animals then consume for energy. In order for photosynthesis to take place, the plant must have sunlight. Is photosynthesis an endothermic or exothermic reaction?
