If a pure substance consists of hydrogen and oxygen and a mixture consists of hydrogen and oxygen:

both the pure substance and the mixture will be identical

the pure substance will still keep the properties of both the hydrogen and the oxygen

the mixture will always have the same ratio of hydrogen and oxygen

the components of the pure substance will not be able to be separated by physical means
