Question

The formation of CO and CO\(_2\) illustrates the law of:

• A. reciprocal proportion
• B. conservation of mass
• C. multiple proportion
• D. constant composition

Hint:

Law of multiple proportions applies when two elements form more than one compound.

Answer 1

The Correct Option is C

Step 1: CO and CO\(_2\) are formed by the same elements (C and O).
Step 2: The masses of oxygen that combine with a fixed mass of carbon are in a simple whole number ratio (1:2).
