PLEASE HELPPP Given the following reaction: 2 K3PO4 + Al2(CO3)3 → 3 K2CO3 + 2 AIPO4
If I perform this reaction with 150 g of Potassium phosphate and 90 g of Aluminum
carbonate, what is my theoretical yield in grams of Potassium carbonate? What are my
limiting and excess reactants? If the reaction results in 125 g of Potassium carbonate,
what is my percent yield?
what are the excess reactants, what is the actual yield, what is the limiting reactant?

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
