Compare and contrast exothermic and endothermic reactions. Cite examples from the achieve3000 article "The Car That Runs on Chocolate" to support your comparison. Also cite examples from what you may already know to support your comparison. Write this in a 7th grade level with 5 short sentences

Answer 1

Exothermic and endothermic reactions are two types of chemical reactions that involve energy changes. In exothermic reactions, energy is released, making the surroundings warmer. For example, when chocolate is burned, it produces heat and light, which is an exothermic reaction. On the other hand, endothermic reactions absorb energy from the surroundings, making them cooler. A common example is photosynthesis, where plants take in sunlight to create food. The article "The Car That Runs on Chocolate" shows how chocolate can be used in an exothermic reaction to power a car!
