Answer 2

Metals on combustion produce basic oxides and non-metal produce acidic oxide. All metals do not occur in the free state. Thus, the assertion is correct but the reason is incorrect.

Explanation:

• A combustion reaction involves a reaction with oxygen.
• Metals react with oxygen to form basic metal oxides.
• On the other hand, non-metals react with oxygen to form acidic oxides.
• Therefore, metals on combustion form basic oxides while non-metals on combustion form acidic oxides.
• All metals do not occur in the free state.
• Only certain less reactive metals such as gold, platinum and silver occur in the free state.
• Thus, the assertion is correct but the reason is incorrect.
