Your laboratory manual calls for you to mix 13.0g of butanol, 21.6g of sodium bromide and 33.8 g of h2so4 as reactants in the following reaction. c, h,oh + nabr + h2so4 → c. h.br + nahso4+h2o after carrying out this reaction you obtain 16.8g of c. h.br. what is your percent yield for this reaction?

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?
