How does a mixture of hydrogen and oxygen differ from a compound of hydrogen and oxygen?

A mixture of hydrogen and oxygen means that the two gasses would be mixed together, but remain chemically distinct from one another and retain their own properties. You would still have separate hydrogen and oxygen molecules. In a compound of hydrogen and oxygen, water, the two elements are chemically combined to form a new substance with its own set of properties.

What gas is produced when manganese dioxide ans hydrogen peroxide are mixed?

Oxygen gas is produced when manganese dioxide and hydrogen peroxide are mixed. This reaction occurs as the manganese dioxide acts as a catalyst to decompose the hydrogen peroxide into water and oxygen gas.


Why does hydrogen pop louder when lit if it is first mixed with air?

The pop you hears is a result of the hydrogen reaction with oxygen. When it is mixed with air, all of the hydrogen is readily in contact with oxygen, and the reaction can proceed much more rapidly.
