Solution
Correct Answer:
Simple whole numbers
Law of Multiple Proportions (Dalton):
- Definition: If two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in the ratio of small whole numbers.
- Example: In CO (12 g C with 16 g O) and CO2 (12 g C with 32 g O), the ratio of masses of oxygen combining with 12 g C is 16:32, which simplifies to 1:2 (simple whole numbers).
This easy difficulty chemistry question is from the chapter some basic concepts in chemistry, covering the topic of laws of chemical combination. It appeared in the 2025 exam.
