D

Magnesium

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
In aluminothermite process Al is reducing agent. It reduces oxides of less EP metal oxides into metals like Fe, Cr Mn etc.
`{:(Cr_(2)O_(3)+2Al to 2Cr+Al_(2)O_(3)+"heat"),(Fe_(2)O_(3)+2Al to 2Fe+Al_(2)O_(3)+"heat"),(3Mn_(3)O_(4)+8Al to 8Mn+Al_(2)O_(3)+"heat"):}`
