2. If a solution of KNO, has 80 g/100 of
water at 70 °C, what is its saturation?
Unsaturated, saturated, or
supersaturated?

3. Which substance does not follow the
trend of increasing solubility with a rise
in temperature?

4. According to what you've read, why is
this probably the case for this substance?

5. If there is 140g of KI per 100 g of water and the solution is saturated, what must it’s temperature be?

6. How would you make a supersaturated solution of KClO3?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

True or false graphs must include scales that increase by the same amount
