Chemistry Laws Chapter 2

Question 1

Law of Definite Proportions

Answer 1

All samples of pure compound contain the same elements in the same proportion by mass.

Question 2

Law of Multiple Proportions

Answer 2

The masses of one element which combine with a fixed mass of the second element are in a ratio of WHOLE NUMBERS. Compounds have whole number ratios to each other.

Question 3

Laws of Definite and Multiple Proportions #1

Answer 3

If two samples have the same elements in the same mass ratios, they are likely the same type of compound.

Question 4

Laws of Definite and Multiple Proportions #2

Answer 4

If two samples have the same elements in different mass ratios, they are different compounds.

Question 5

Laws of Definite and Multiple Proportions #3

Answer 5

The masses are related to relative amounts of each type of atom in a compound.
