Answer & Solution
Correct Answer
(A) 4
Step-by-step Solution
Detailed explanation
Metal + Oxygen \(\longrightarrow\) Metal oxide Metal oxides are basic in nature. Therefore, \(\mathrm{Na}_2 \mathrm{O}\), \(\mathrm{MgO}\) and \(\mathrm{CaO}\) are basic in nature. \(\mathrm{ZnO}\) is amphoteric in nature i.e., it can react with both acids as well as alkalis to…
