MCQ
How many moles of $H_2O$ are liberatd when one mole hydrated $MgCl_2$ is heated?
- A$6$
- ✓$5$
- C$4$
- D$3$
✓
Answer
Correct option: B.
$5$
b
$MgC{l_2} \cdot 6{H_2}O\;\xrightarrow{\Delta }{\text{ }}MgO{\text{ }} + {\text{ }}2HCl{\text{ }} + {\text{ }}5{H_2}O$
$MgC{l_2} \cdot 6{H_2}O\;\xrightarrow{\Delta }{\text{ }}MgO{\text{ }} + {\text{ }}2HCl{\text{ }} + {\text{ }}5{H_2}O$
