Question

exothermic reaction: a chemical in which thermal energy is. the products will usually feel. the products will have than the reactants. more chemical bonds are being in the products than being in the reactants. examples: precipitation,, freezing cubes, fireworks. graphing thermal energy endothermic reactions: heat is into the system from the. exothermic reactions: heat is to the surroundings from the. model exothermic reaction surroundings system (reactants) e decreases (generally heat flow). model endothermic reaction surroundings system (reactants) e increases (generally heat flow) energy released = temperature increases! energy absorbed = temperature decreases!

Explanation:

Exothermic reactions release thermal energy, making products feel hot, with products having lower energy than reactants and more bond - formation than bond - breaking. Examples include precipitation, freezing water cubes, fireworks. Endothermic reactions absorb heat from the surroundings, while exothermic reactions release heat to the surroundings.

Answer:

Exothermic Reaction: a chemical reaction in which thermal energy is released. The products will usually feel hot. The products will have lower energy than the reactants. More chemical bonds are being formed in the products than being broken in the reactants. Examples: Precipitation, freezing water cubes, fireworks. Endothermic Reactions: Heat is absorbed into the system from the surroundings. Exothermic Reactions: Heat is released to the surroundings from the system.
