Select the three answers that are correct concerning a saturated solution of pbcl2. pbcl2(s) pb+2(aq) + 2cl-(aq) the system is in equilibrium. the rate of dissolving is equal to the rate of recrystallization. the concentration of pbcl2 is greater than normal. the concentration of the products only is used to determine the ksp.

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?
