Q
Chemical reactions do one of two things to energy
A
release or absorb
4
Q
Exothermic Reactions
A
hot
energy of product is less than reactants
energy released from chemical bonds
more energy released from breaking the bonds than forming the new bonds
5
Q
Endothermic Reactions
A
cold
energy of product is more than reactants
energy is absorbed into the new chemical bonds
energy is absorbed from the surrounding environment and temp decreases
