The frequency of a line in the emission spectrum of an atom indicates the amount of A
kinetic energy gained by the nucleus when heat energy is added to the atom.
B.
energy characteristically released when an electron drops to a lower energy state.
C.
energy released by the nucleus when heat energy is removed from the atom.
D.
charge characteristically lost when an electron drops to a lower energy state.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
