Answer» Metal A burns in air and FORM A2O3.Metal B burns in air to form BOBoth the oxides can react with HCl as well as NAOH to give SALT and water(a) What is the nature of oxide A2O3 :A2O3 is amphoteric in nature .b) What is the nature of oxide BO ?BO is Amphoteric in natureC) An example Of metal A is Aluminium4Al+3O2----> 2Al2O3D) Metal B is Zinc2Zn +02---->2 ZnO
