Question

Thermite process is used to extract metals

• A. when their oxides can't be reduced by carbon
• B. when their carbonates do not yield oxides by thermal decomposition
• C. when their sulphides can't be converted into oxides by roasting
• D. when their melting points are very high

Answer 1

The correct option is A when their oxides can't be reduced by carbon

Thermite process is used to extract metals when their oxides can't be reduced by carbon.

Hence, Option "A" is the correct answer.
