Questions and Answers

According to Dalton's Law of Partial Pressures, what is the total partial pressure of a gas mixture?

  • The product of all the partial pressures of its components
  • Double the partial pressure of the most soluble gas
  • Equal to the partial pressure of the most abundant gas
  • The sum of all the partial pressures of its components (correct)
  • How does Henry's Law explain the concentration of a gas in a solution?

  • Depends on the color of the solution
  • Depends on the temperature of the solution
  • Depends on the volume of the gas
  • Depends on the solubility and partial pressure of the gas (correct)
  • What law states that volume is directly proportional to temperature as long as pressure remains constant?

  • Boyle's Law
  • Dalton's Law
  • Henry's Law
  • Charles' Law (correct)
