Question

Two samples 'm' and 'n' of slaked
lime were obtained from two
different reactions. The details
about their composition are as
follows:
‘sample m' mass : 79
Mass of constituent oxygen : 2g
Mass of constituent calcium : 59
sample n' mass : 1.49
Mass of constituent oxygen : 0.49
Mass of constituent calcium : 1.0g
Which law of chemical combination
does this prove? Explain.

Answer 1

Answer:

Law of constant proportion

Explanation:

Law of constant proportion states that "The proportion by weight of the constituent elements in various samples of compound is fixed in ratio"

for ex: in sample m,the ratio of proportion of elements

Ca:O=5:2

in sample n, the ratio of proportion of elements

Ca:O=1.0:0.4

=10:4

=5:2

on simplifying the ratio proportion by mass, we get same values.

That verifies "Law of constant proportion"
