All regular solutions with positive heats of mixing have the same value of the activity of its components (a or b) at the critical point of the miscibility gap calculate this activity b. plot temperature versus ag for a regular solution miscibility gap a.

How does litmus paper indicate an acid?

Write a net ionic equation to show that hydrofluoric acid, behaves as an acid in water.

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?
