b) The car door handle pulls back on Jahkaya with 50N of force to the right.
c) The car also applies a force of 50N to the left, for a total of 100N.
d) Jahkaya's hand applies a second force to the car door handle of 50N

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.
