All living beings need oxygen for respiration is essential for combustion . Oxygen dissolved in water supports aquatic life.
The active gas in air is HYDROGEN. i learnt this learning my chemistry.
21% of oxygen is in the air so 0.21 is your answer
The slow destruction of a metal through its reaction with oxygen in the air is called CORROSION
oxidation

No. Oxygen is an element that typically comes in the form of O2. Air is a mixture of gasses and Oxygen is just one of them. Air is about 21% oxygen and 78% nitrogen with another 1% being a variety of other gasses.
The group of organs that take in oxygen from the air is called your respiratory system.
The lungs take in oxygen directly from the air.
Oxygen is the required gas that is necessary for combustion
Oxygen.
Yes.Air is a mixture of gases like oxygen,nitrogen,etc. Oxygen is 21% of air so air is 100%. So, air is more than oxygen. -------------------------------------------------------------------------------------------------------------- ok, oxygen is part of air. if something(x) is part of something else(y), the somethings else(y) must be either more or the same as the something(x). geddit?
Part of air is made up of oxygen without which fire can't happen. Air can feed a fire; it contains oxygen.
