Question

Alumino–thermic process is used for the extraction of metals, whose oxides are

  1. (a) Fusible  
  2. Not easily reduced by carbon  
  3. (c) Not easily reduced by hydrogen  
  4. Strongly basic  

The correct answer is: Not easily reduced by carbon


    Alumino thermite process involves reduction of oxides such as F e subscript 2 end subscript O subscript 3 end subscript comma M n subscript 3 end subscript O subscript 4 end subscript comma C r subscript 2 end subscript O subscript 3 end subscript etc. to metals with aluminum. C r subscript 2 end subscript O subscript 3 end subscript plus 2 A l rightwards arrow A l subscript 2 end subscript O subscript 3 end subscript plus 2 C r capital delta H equals negative text ve end text
