In a ventilated hood in a lab, a student heats barium metal over a flame, and it begins to react with oxygen gas in the air. a white crystalline compound begins to form on the burning barium.
2 ba (s) + o2 (g) --> 2 bao (s) = energy
which statement best describes the reactants and products?
a. equal numbers of barium atoms are in the reactants as in the products.
b. fewer overall atoms are in the products than in the reactants.
c. twice as many oxygen atoms are in the reactants as in the products.
d. more atoms are in the products than in the reactants.
