Explain why mole ratios are central to stoichiometric calculations, a. You must have the balanced chemical equation and know the quantity of one substance
in the reaction
b. Mole ratios allow for the conversion from moles of one substance in a balanced chemical
equation to moles of another substance in the same equation,
c The mass of the reactants will always equal the mass of the products
d. Mole ratios are determined by the coefficients in a balanced equation

How does a nuclear reactor produce electricity? a. high-energy gamma rays are converted by a generator into electricity. b. the heat from the reaction turns water to steam, which runs a generator. c. the reaction produces a stream of electrons that flow through wires and into batteries. d. the heat released from the reaction is used to burn coal or gas to produce electricity. e. control rods absorb the neutrons emitted and release a stream of electrons as electricity.
