A metal A.Which is used for thermite process when heated with oxygen gives oxide b which is amphotetic in nature identify A and B write down the reaction of oxide B with HCL and NaOh

Answer 1

Metal A is aluminum .
Oxide B is aluminum oxide .
reaction with HCl :
Al2O3 +HCl--> AlCl3+ H2O
Reaction with NaOH :
Al2O3 + NaOH --> NaAlO2 +H2O

Answer 2

Answer:

Explanation:

A is aluminium

B is aluminium oxide al2o3+h2o=alcl3+h2o
