Astudent sets up two reactions. reaction 1 uses 0.240 mol/l of reactant, and reaction 2 uses 0.560 mol/l of reactant. how many times faster is reaction 2 compared to reaction 1?

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

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?
