Question

The boiling point of water at level is 100 degree C point of water will be: a) lower, because the atmospheres is higher b) higher, because the atmospheric is higher c) lower, because the atmospheres is lower d) higher, because the atmospheres is lower e) the same, because water always boils at 100 degree C Complete the following statement is Charles's Law, the volumes of a gas_____ when the _____ decreases. a) increases; temperature b) increases; quantity of gas c) increases; pressure d) decreases; temperature e) decreases; pressure In the process known as osmosis, _____ moves through a membrane into an area of _____ concentration. a) solute; lower solute b) solute; higher solute c) solvent; lower solute d) solvent; lower solvent e) solvent; higher solvent A red blood cell will undergo hemolysis in a) water b) 0.9% NaCl c) 5% glucose d) 59% NaCl e) 10% glucose What is the molarity of a solution that contains 17gof NH_3im 1.0 L of solution? a) 34 M b) 2.0 M c) 0.50 M d) 0.029 M e) 1.0 M Which of the following compounds would you expect to be soluble in water? a) CaCO3 b) PbSO_4 c) HgS d (NH_4)_3 PO_4 e) AgCl

Explanation / Answer

Q5.

T = 100°C, P = 1 atm

below selevel, the boiling point of water should -> increase, since more presure is added

above -- > boiling pressure should decrease since atmospheric pressure decreases

Q6.

Charles law relates Volume and Temperature of a gas:

V/T = C

if we increse V, then T must decrease
