How many moles of potassium hydroxide are needed to completely react with 1.73 moles of aluminum sulfate according to the following equation: Al2(SO4)3 + 6 KOH ---> 2 Al(OH)3 + 3 K2SO4

Which terms are used to identify pure substances

How could a student test the effect of removing heat from a gas that is stored in a sealed container? what must occur in order for matter to change states?

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?
