Question

What is the end product when $MgC{l}_2\cdot 6H_{2}O$ is strongly heated?

• A. $MgO$
• B. $MgC{l}_2$
• C. $M{g}_{2}OC{l}_2$
• D. All of the above.

Answer 1

The correct option is A $MgO$

When $MgC{l}_2\cdot 6H_{2}O$ is strongly heated, the end product is $MgO$.
$MgC{l}_2\cdot 6H_{2}O\stackrel{heat}{\to }MgC{l}_2\cdot 2H_{2}O\stackrel{heat}{\to }M{g}_{2}OC{l}_2\stackrel{heat}{\to }MgO$
The byproducts obtained are $H_{2}O$, $HCl$ and $C{l}_2$.
