CHXI01:SOME BASIC CONCEPTS OF CHEMISTRY

306987 Which statement is false for the balanced equation given below?
\(\mathrm{CS}_{2}+3 \mathrm{O}_{2} \rightarrow 2 \mathrm{SO}_{2}+\mathrm{CO}_{2}\)

1 One mole of \(\mathrm{CS}_{2}\) will produce one mole of \(\mathrm{CO}_{2}\).
2 The reaction of 16 g of oxygen produces 7.33 g of \(\mathrm{CO}_{2}\).
3 The reaction of one mole of \(\mathrm{O}_{2}\) will produce \(2 / 3\) mole of \(\mathrm{SO}_{2}\).
4 Six molecules of oxygen requires three molecules of \(\mathrm{CS}_{2}\).
