Question

which statement about exothermic reactions is true?
energy from an outside source is continuously being added.
more heat is given off than is put into the reaction.
the reactants create energy to form products.
the reaction container always feels cold.

Explanation:

• Exothermic reactions release heat. The heat released is more than the heat (if any) absorbed during the reaction.
• Energy is not “created” (violates conservation of energy). If energy from an outside source is continuously added, it is an endothermic reaction. An exothermic reaction container feels warm as heat is released.

Answer:

More heat is given off than is put into the reaction.
