Question

Assertion :$MgO$ is reduced by $Si$ whereas $Si{O}_2$ can be reduced by $Mg$ Reason: $Si$ reduces $MgO$ at high temperature $Mg$ is more electropositive than $Si$ and thus reduces $Si{O}_2$

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

At temperatures less than 1966 K, $Mg$ can reduce $Si{O}_2$ and above 1966 K, $Si$ can reduce $MgO$.
