1 Answer?AB

2 Which of the following apply?A Law of Definite ProportionsB Law of Multiple Proportions

1. Mass ratio of the 2 elements in one compound cannot vary. Example: NaCl cannot be NaCl2, only NaCl

2. Mass ratio of elements in 2 different compounds that both have the same elements, can vary. Example: CuCl - Cu & Cl can also combine as

CuCl2

3. Mass ratio of elements within one compound cannot change or vary its ratio.
