A reaction where more energy is absorbed than released is:

• endothermic

• exothermic

• not enough information

• depends on the amount of energy

A reaction where more energy is released making the products than is absorbed breaking apart the reactants is:

• exothermic

• endothermic

• depends on the compounds

• depends on the amount of energy

In an endothermic reaction energy is:

• absorbed by the system

• released into the surroundings

• created by the reactants

• absorbed by the observer
