Question

6.
The formation of PbO, Pbo, and Pb Oą, reveals that the masses of oxygen combined with 10
is a simple whole number ratio. This illustrates
1) Law of conservation of mass
2) Law of definite proportions
3) Law of constant proportions
4) Law of multiple proportions​

Answer 1

Answer:

4) Law of multiple proportions

Explanation:

When two different elements is combined together to form more than one product the ratio of masses of one element which combines with the fixed mass of another element is always a simple whole number ratio.  Thank You

Answer 2

The formation of PbO, Pbo, and Pb Oą, reveals that the masses of oxygen combined with 10 is a simple whole number ratio. This illustrates (4) Law of multiple proportions

Explanation:

1.law of multiple proportions, statement that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

2.For exmaple: carbon monoxide (CO and carbonadoed `CO.A careful study of the actual numerical values of these proportions led Dalton to propose his law of multiple proportions.

3.This was an important step toward the atomic theory that he would propose later that year, and it laid the basis for chemical formulas for compounds.
