(A) All metal carbonates react with acid to give a salt, water and carbon dioxide

(B) All metal oxides react with water to give salt and acid

(C) Some metals react with acids to give salt and hydrogen

(D) Some non metal oxides react with water to form an acid

Answer

1. All metal carbonates react with acid to give salt, water and CO ₂ . For eg:
   
   
   
2. All metal oxides react with water to give metal hydroxides and not salt and acid. For eg.
   
3. Some metals react with acids to give salt and hydrogen . For eg.
   
   
4. Some non-metal oxides react with water to form an acid . For eg.

So, the correct option is (b) All metal oxides react with water to give salt and acid
