A metal A, which is used in thermite process, when heated with oxygen gives an oxide B, which is amphoteric in nature? Identify A and B. Write down the reactions of oxide B with \(HCl\) and \(NaOH\).
 
\(A+O_2(g)+Heat→B(s)\)
 
Where A is ; B is
 
B is amphoteric in nature.
 
The reaction of B with \(HCl\):
 
\(B+6HCl→C+3H_2O\)
 
Where, C is
 
The reaction of B with \(NaOH\):
 
\(B+2NaOH→D+H_2O\)
 
Where, D is
