Which statements below are TRUE of exothermic reactions. Choose the 6 statements that are TRUE.
a
An exothermic reaction is a reaction in which heat is released from the system to the surroundings.
b
An exothermic reaction is a reaction in which heat is absorbed into the system from the surroundings.
