Question

In any pure sample of CO2, the ratio of the mass of carbon to the mass of oxygen is always the same. You can justify this ratio by the fact that compounds are composed of which of the following?

A. Atoms whose masses do not change during a chemical reaction
B. Atoms whose chemical properties do not change during a chemical reaction
C. Different molecules which together produce the observed elemental ratios
D. Identical molecules created from atoms combined in whole number ratios

Answer 1

@JFraser It's C right?

Answer 2

@ganeshie8 It's C right?

Answer 3

@Preetha It's C right?

Answer 4

@ParthKohli It's C right?

Answer 5

This particular question asks about the mass ratios of the components in \(CO_2\), but option C asks about the idea behind the law of constant composition.

Answer 6

It's not B either
