1.	It is true that under certain coditions magnesium can reduce SiO_2 and silicon can reduce MgO. What are those conditions ?
Answer» Solution :Below 1623 K (or `1350^@C`), magnesium can reduce `SiO_2` but above 1623 K (or `1350^@C`), silicon can reduce `MgO`. This can be infrred from `DELTAG^@` vs T plots.
