Which law compares the different compounds \(CO\) and \(CO_2\) made from carbon and oxygen?

Answer and explanation

Correct answer: Law of multiple proportions

The law of multiple proportions applies when the same two elements form more than one compound and the masses of one element that combine with a fixed mass of the other are in a simple whole-number ratio. Carbon and oxygen form both \\(CO\\) and \\(CO_2\\), so this is exactly the required situation. For a fixed mass of carbon, the oxygen combined in the two compounds is in the ratio \\(1:2\\), a simple whole-number ratio. Therefore, the correct law is the law of multiple proportions.

Option D is correct. The law of definite proportions applies to one pure compound, whose elements have a fixed mass ratio; it does not compare two different compounds. Conservation of mass concerns total mass in a chemical reaction, while gaseous volumes concerns reacting gas volumes. The key clue is the presence of two compounds made from the same two elements.
