Answer to this is O-atom.
Explanation: The Bronsted acid-base theory is the backbone of chemistry. This theory focuses mainly on acids and bases acting as proton donors or proton acceptors.
where 
is the Lewis Acid and 
is the Lewis Base and 
is the Covalent Bond.
Reaction of dissociation of 
in 
is given as:
In this reaction O-atom has lone pair in water and therefore it accepts the proton from 
forming a Lewis Base.
Answer:
1-10 μL
Explanation:
Gas Chromatography (GC) is a method of separating the constituents of a complex mixture by taking advantage of their different rates of movement in a solvent over an adsorbent medium. Gas Chromatography (GC) is a means of separation and analysis that utilises fractional separation. It is based on the principle that if a fluid containing a number of substances is allowed to pass through an adsorbent medium , the different substances in the fluid may travel at different rates and be separated.
The approximate volume injected through an inlet by using a split injection into a Gas Chromatography (GC) contains a sample with an approximate value of analyte which varies from 1-10 μL.
In order to adjust for injection volume inaccuracy, the technique used is known as Internal Standard.
