1. Explain in detail how oxygen can be preparedfrom hydrogen peroxide.

1.	1. Explain in detail how oxygen can be preparedfrom hydrogen peroxide. Mention the safetyprecautions to be undertaken while carryingout the experiment.
Answer» EXPLANATION: To prepare oxygen ...poured the HYDROGEN PEROXIDE into flask that already conatin MnO2 ( manganese OXIDE) then collect the gas precaution: Handle with care. In case of skin contact, rinse the AFFECTED areas well with water. Store unused hydrogen peroxide in a freezer reserved for laboratory chemicals only. Manganese dioxide is a strong oxidant, avoid contact with organic material.
