Consider the potassium permanganate reaction again.

2kmno4 + 16hcl → 2kcl + 2mncl2 + 8h2o + 5cl2

how many moles of water are produced when 3.45 moles of kmno4 react? give your answer to the nearest 0.1 moles.

i know the answer is 13.8 moles but i dont know how to find this. explain.

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?
