MCQ
Which statement is false for the balanced equation given below

             $CS_2 + 3O_2 \to 2SO_2 + CO_2$

  • A
    One mole of $CS_2$ will produce one mole of $CO_2$
  • B
    The reaction of $16\,g$ of oxygen produces $7.33\,g$ of $CO_2$
  • C
    The reaction of one mole of $O_2$ will produce $2/3$ mole of $SO_2$
  • ✓
    Six molecules of oxygen requires three molecules of $CS_2$
✓

Answer

Correct option: D.
Six molecules of oxygen requires three molecules of $CS_2$
d
Here for $3$ molecules of Oxygen , we need $1$ molecule $CS _2$

Hence for $6$ molecules of Oxygen, we need $2$ molecules $CS _2$

Hence option $D$ is the answer.
