7. Endothermic reactions absorb a lot of energy. Exothermic reactions give off a lot of energy. Which type of reaction has a higher activation energy? Which one takes more energy to break up the bonds of the reactants?(1 point)
Endothermic reactions have a higher activation energy. Exothermic reactions require more energy to break up the bonds of the reactants.****
Exothermic reactions have a higher activation energy. Endothermic reactions require more energy to break up the bonds of the reactants.
Exothermic reactions have a higher activation energy. Exothermic reactions require more energy to break up the bonds of the reactants.
Endothermic reactions have a higher activation energy. Endothermic reactions require more energy to break up the bonds of the reactants.
8. Why is thermal energy (heat) required to freeze ice into crystals?(1 point)
Heat must be absorbed by the reactants and the products.
Heat must be released by the products in order to convert from the reactants.
Heat must be absorbed by the products in order to convert from the reactants.
Heat must be released by the reactants and the products. ****
Im not really sure on 8, this is an educated guess)))
