Hydrogen and oxygen—H2O2

Answer 2

Answer:

Hope it's helps you my dear friend

Explanation:

1.Nitric acid - HNO3 (hydrogen,nitrogen and oxygen)

2.Blue vitriol - CuSO4.5H2O (carbon,sulphur,hydrogen and oxygen)

3.Acetic acid - CH3COOH (carbon,hydrogen and oxygen)

4.Ethanol - CH3CH2OH (carbon,hydrogen and oxygen)

5.Hydrogen peoxide - H2O2 (hydrogen and oxygen)
