Question 5 (3 points)
Which statements below are TRUE of endothermic reactions. Choose the 6 statements that are TRUE.
a
An endothermic reaction is a reaction in which heat is released from the system to the surroundings.
b
An endothermic reaction is a reaction in which heat is absorbed into the system from the surroundings.
