Why can evaporation be used to separate a mixture? check all that apply.

one or more components has a lower boiling point than the desired component.

the desired component has a different density than the other components.

the mixture is a solution that contains a substance that will crystallize out.

the desired component has the smallest particles in the mixture.

the desired component has a higher boiling point than the other components.

he causes some of the components to change into a gas.

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?
