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 6th grade level with 5 short sentences

Answer 1

Exothermic and endothermic reactions are two different types of chemical reactions that involve energy changes. An exothermic reaction releases energy, usually in the form of heat, like when wood burns in a fire. In contrast, an endothermic reaction absorbs energy from its surroundings, like when ice melts. In the article "The Car That Runs on Chocolate," scientists created a way for a car to run on chocolate, which involves endothermic reactions where energy is taken in to make the chocolate usable as fuel. This contrasts with traditional fuels that release energy when burned, showing how both types of reactions are important in different ways.
