Which question correctly describes how light is produced *
electrons jump to higher energy level, and then fall back down again very quickly releasing energy
electrons start in the excited state and then lose energy after a long period of time
electrons absorb energy to go to the ground state and then release energy
electrons jump to a lower energy level and then fall to the excited state and release energy
How many rings would you draw in a Bohr Diagram for an atom with an atomic number of 56 and an electron configuration in the ground state
five rings because that atom has five electrons
six rings because that atom has six energy levels
four rings because that atom has four valence electrons
six rings because that atom had two valence electrons jump to a higher energy level.
Both 2 and 4

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?
