A
Absorbs heat energy from surroundings
3
Q
Formula for EXOTHERMIC
Product/reactant/energy
A
Reactants —-> Product +energy
4
Q
Formula for ENDOTHERMAL
Product/reactant/energy
A
Energy + reactant —-> Product
5
Q
How do u know if the energy is on the reactant side or product side
A
Negative number = EXOTHERMIC/left side
Positive number = ENDOTHERMAL /right side
