In an endothermic reaction, energy is absorbed from the surroundings in order to overcome the activation energy of the reaction. This means that the reactants have more energy than the products, and so the products are more stable. Energy is conserved because the total amount of energy in the system is the same before and after the reaction.

Q: How is energy conserved in an exothermic reaction?
A: In an exothermic reaction, energy is released in the form of heat. This heat can be used to do work, such as powering a machine. The energy that is released is equal to the energy that was required to break the bonds between the reactants.
Q: How does energy transform during an endothermic or exothermic reaction?
A: In an endothermic reaction, energy is absorbed from the surroundings, usually in the form of heat. This energy goes into breaking the bonds in the reactants, and forming the new bonds in the products.
In an exothermic reaction, energy is released to the surroundings, again usually in the form of heat. This energy comes from the breaking of bonds in the reactants, and the formation of new bonds in the products.
Q: Is energy conserved in a reaction?
A: In a chemical reaction, energy is conserved. The total amount of energy in the reactants is equal to the total amount of energy in the products.
Q: What happens in an endothermic reaction?
A: In an endothermic reaction, the products have more energy than the reactants. This means that the reactants must absorb energy from the surroundings in order to create the products.
