Questions and Answers

What does the law of multiple proportions state about elements A and B?

  • The mass of A is variable even if the mass of B is fixed.
  • They can combine in whole number ratios when forming more than one compound. (correct)
  • The combination of A and B always results in non-integer mass ratios.
  • They can only form one compound together.

    Study Notes

    Law of Multiple Proportions

    • If two elements (A and B) form multiple compounds,
    • the masses of element A that combine with a fixed mass of element B are in a ratio of small whole numbers.
