The mole and avogadro’s number are now almost synonymous with each other. we say that one mole of a substance is the amount that contains avogadro’s number of particles. however, both concepts were developed independently at different times. analyze the theories and definition of both of these concepts. then, explain why it is correct to define a mole in terms of avogadro’s number and vice versa.

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.
