Law of constant proportions — task. Chemistry CBSE Live product, Class 9.

Choose the correct answer:

Two samples of carbon monoxide (\(CO\)) are decomposed. Sample '\(A\)' has \(12 g\) of carbon and \(16 g\) of oxygen. Sample '\(B\)' has \(24 g\) of carbon and \(32 g\) of oxygen. Do they follow the law of constant proportions?

No, ratios are different
No, oxygen is double in sample '\(B\)'
Yes, same \(C:O\) ratio in both
Yes, but only sample '\(B'\) is \(CO\)
