11. a water molecule is made of hydrogen and oxygen atoms and has the formula h2o. how
would a mixture of hydrogen and oxygen differ from the compound known as water?
o a. the mixture would need to have more oxygen atoms than hydrogen atoms.
ob. the mixture would not need to have a certain ratio of hydrogen atoms to oxygen atoms.
the mixture would be a chemical combination of the elements instead of a physical
combination
od. the individual properties of hydrogen and oxygen would not be retained in a mixture,

The mixture would not need to have a certain ratio of hydrogen atoms to oxygen atoms is the difference between mixture of hydrogen and oxygen differ from the compound known as water.

Option B

Explanation:

Water molecule contains one oxygen atom and two hydrogen atoms which reacted chemically. This means once they go through the chemical reaction process, they lose their individual properties and obtain new properties of water.  

If oxygen and hydrogen form a mixture, they retain their individual properties, they don't need any ratio or and most importantly there is no chemical reaction taking place. Hydrogen Peroxide isn't a mixture but a compound formed when two hydrogen atoms react with two oxygen atoms. The most important factor distinguishing between compound and mixture is a chemical reaction.
