Question

Two samples of lead oxide were separately reduced to metallic lead by heating in hydrogen. The percentage weight of lead from one oxide was half the percentage weight of lead obtained from the other oxide. The data illustrates the law of:

• A. reciprocal proportions
• B. constant proportions
• C. multiple proportions
• D. equivalent proportions

Answer 1

Answer: (C)

multiple proportions

The law of multiple proportions say that If two elements form more than one compounds between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.
