Consider these two cases. case 1: an electron jumps from energy level 5 to energy level 2 in an atom. case 2: an electron jumps from energy level 5 to energy level 1 in an atom. for case 1, what happens when an electron jumps from energy level 5 to energy level 2 in an atom? a photon is emitted by the atom. a photon is absorbed by the atom. a proton is absorbed by the atom. a proton is emitted by the atom. assuming that both cases describe hydrogen‑like atoms with one electron, for which case is more energy emitted or absorbed? more energy is emitted or absorbed for case 1. it is impossible to tell. the energy is the same for both cases. more energy is emitted or absorbed for case 2.

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?
