Calculate the moles of calcium chloride (CaCl2) needed to react in order to produce 85.00 grams of calcium carbonate (CaCO3).

Juan argues that when you burn coal, you use up the coal, and hence you use up all of Its energy, and this results in a net loss of energy in the universe. How could you fix Juan's argument? The total energy in the universe remains constant because
A. the chemical energy of coal is converted to thermal energy
B. the kinetic energy of coal is converted to potential energy
C. the elastic potential energy of coal is converted to thermal energy D. the gravitational potential energy of coal is converted to elastic potential energy
