The addition of solute particles into a solution causes: A. the solute particles to form seed crystals and make the solution freeze more easily.
B. the solvent particles to be attracted to the solute particles and to have less kinetic energy.
C. the solvent particles to be spread further out and have more to move, increasing their kinetic energy.
D. the solute particles to bump the solvent particles out of the solution, making it easier to boil.

Compare and contrast physical changes with chemical changes.

Which three statements represent the benefits of performing experiments using computer simulations?

Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. which equation should you use? n=pv/rt what is the number of moles present? ⇒ 0.056 mol a sample of n2 gas occupying 800.0 ml at 20.0°c is chilled on ice to 0.00°c. if the pressure also drops from 1.50 atm to 1.20 atm, what is the final volume of the gas? which equation should you use? v2= p1v1t2/p2t1 what is the final volume of the gas? ⇒ 932 ml these are the answers
