How do balanced chemical equations show the conservation of mass? they show that the atoms in the products may be different than the reactants as long as the mass does not change. they show that the atoms in the products are the same as in the reactants, but the number of atoms must change. they show that the number of atoms of each element is the same in the products and

Which statement is true according to the kinetic theory? a. molecules of different gases with the same mass and temperature always have the same average density. b. molecules of different gases with the same mass and temperature always have the same average volume. c. molecules of different gases with the same mass and temperature always have the same pressure. d. molecules of different gases with the same mass and temperature always have the same molecular mass. e. molecules of different gases with the same mass and temperature always have the same average kinetic energy.
