Answer:
the changing tempure in rocks causing it to back apart
a resource that cannot be replenished in a short period of time
Answer:
63.6%
Explanation:
The given compound is:
N₂O;
The problem here is to find the percent composition of nitrogen in the compound.
First find the molar mass of the compound:
Molar mass of N₂O = 2(14) + 16 = 44g/mol
So;
Percentage composition of Nitrogen = x 100 = 63.6%
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.
A single bond contains <u>two</u> shared electrons.
