In two separate experiments, 0.36g and 0.71g of chlorine combined with a metal X to give Y and Z respectively. An analysis showed that Y and Z contain 0.20g and 0.40g of X respectively. The data above represents the law of ?
-
A.
multiple proportion -
B.
conservation of mass -
C.
constant composition -
D.
reciprocal proportion
Correct Answer: Option C
Explanation
0.36g of Cl combines with 0.2g of x
1g of Cl will combine with (frac{1 times 0.2}{0.32}) = 0.56
0.71g of U combines with 0.49g of x
1g of U will combine with (frac{1 times 0.4}{71}) = 0.56
Ratio 0.56 : 0.56 = 1:1
