Show by a chemical reaction that `Na_2O` is a basic oxide.

Show by a chemical reaction with water that 'Na_2 O' is a basic oxide and 'Cl_2 O_7' is an acidic oxide.

In the above chemical reaction, Which atom is oxidised ? 2SO_2 + O_2 rarr 2SO_3

Write chemical reactions to justify that H_2O_2 can function as an oxidising as well as reducing agent.

Assertion : Nitric oxide is an acidic oxide while CrO_(3) is a basic oxide. Reason : Oxides of metals are generally acidic while oxides of non-metals are generally basic.
