38) SEP Develop a Model Imagine you have a box and a set of red and green balls. The red balls represent solute particles, and the green balls represent solvent
particles. Sketch a model showing how the number of red balls doesn't change as
more green balls are added. Use your model to show how the percent by count of
red balls to total balls decreases.

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?
