Question

iron and chlorine form two compounds,A and B.Compound a contains 1.27 g ofchlorine for each 1 g of iron whereas compound b contains 1.9 g of chlorine for each 1 g of iron. show the masses of chlorine are in the ratio 2:3.do they obey the law of multiple proprotion?explain.

Answer 1

Answer:

Explanation:

If it is the 1.27 ands 1.9 are not whole numbers because of that the multiple proportions

Answer 2

Answer:

The masses of chlorine are in proportion $2:3$.

And yes, it obeys the law of multiple proportions.

Explanation:

Given,

The mass of chlorine in compound A = $1.27g$

The mass of iron in compound A = $1g$

The mass of chlorine in compound B = $1.9g$

The mass of iron in compound B = $1g$

To prove: The masses of chlorine are in the ratio $2:3$.

As we know,

• According to the law of multiple proportions, when the two elements combine to form two or more compounds, the weight of an element with a fixed weight of the other element will always be in ratios of small whole numbers.

Therefore,

• The chlorine masses are in the ratio = $\frac{mass of chlorine in compound A}{mass of chlorine in compound B}$
• The chlorine masses are in the ratio = $\frac{1.27}{1.9}$ = $\frac{2}{3}$ = $2:3$.

Hence, the masses of chlorine are in the ratio of 2:3.

Now,

• The proportion of the masses of chlorine is a small whole number.
• Therefore, yes, it obeys the law of multiple proportions.
