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