Science Question on Metals and Non-Metals
A metal ‘X’ is used in the thermite process. When ‘X’ is heated with oxygen, it gives an oxide ‘Y’, which is amphoteric in nature. ‘X’ and ‘Y’ respectively are:
A
Mn, MnO₂
B
Al, Al₂O₃
C
Fe, Fe₂O₃
D
Mg, MgO
Answer
Al, Al₂O₃
Explanation
Solution
Aluminium (Al) is used in the thermite process, and it forms aluminium oxide (Al₂O₃), which is amphoteric as it reacts with both acids and bases.
