50 mL of water (density = 1.00 g/mL) are added to 50 mL of alcohol (density = 0.80 g/mL), producing a mixture with a volume of 95 mL. What can be said about the density of the mixture? t must equal the average density of the two liquids.

It must be greater than the average density of the two liquids.

It must be smaller than the average density of the two liquids.

none of the above

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?
