Question

Bonus Question: True or false I. Sea water is a homogeneous solution containing salts and water. Answer: 2. In the solution process, the breaking of solute particles is an endothermic process because energy is released when molecules are separated Answer: 3. Entropy change in the solution process is always positive. Answer: 4, Polar solutes are generally soluble in polar solvents. Answer: 5. Decreasing partial pressure increases the solubility of gases and solids. Answer: 6. Solubility of gases in water generally decreases at lower temperature. Answer 7. Solubility of gases in water generally decreases at lower partial pressure. Answer: 8. Solubility of solids in water generally increases at lower temperature. Answer 9. Addition of a nonvolatile solute to a solvent raises the vapor pressure and reduces the boiling point of the solution. Answer: 10. The semipermeable cell membrane in red blood cells permits water and small molecules such as salts to pass through. Answer

Explanation / Answer

Q1

TRUE seawater must be homogeneous, since it is a single phase, i.e. aqueous (salts are in ions)

Q2

true, the interactions must be broken, so it requires energy

Q3

false, depends on species present

Q4

true, according to like dissolves like

Q5

false, according to henry law, we must increae partial pressure to increase solubility

Q6

False, they increase in solubilit

Q7

true, as P partial decreases, solubiltiy of gas decreases

Q8

false, typically, salts incresaes in soluton as T increases

Q9

false, it redues vapor pressure, and increses BP

Q10

True, this is the point of semi membranes
