Ii) prepare a stock solution of isopropanol 1) prepare 25.00 ml of solution which is 0.60 m in isopropanol (0.785 g/ml) and 1.00 m in hcl. add the reagents in the following order into the volumetric flask provided: about 10 ml of deionized water 2.0 m hcl (use a graduated cylinder--if the flask gets warm, cool it in running tap water, but be careful not to get tap water into the flask) isopropanol (use a 1 ml graduated pipet).

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?
