4. How many moles of Cl2, are obtained by the
decomposition of 6.3 moles of POCI3?

6.3moles

Explanation:

The balanced chemical equation for the decomposition of phosphorus oxychloride (POCl3) is as follows:

POCl3 → POCl + Cl2

Based on the above decomposition reaction, it shows that;

1 mol of POCl3 will decompose to give 1 mole of Cl2

Hence, 6.3 moles of POCI3 will give 6.3 moles of Cl2.

the answer is the
