What is the approximate volume injected into a GC? 10-50 μL 500-1000 μL 1-10 μL 100-500 μL 50-100 μL What technique is used to a
DiKsa [7]

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.

The Henry's Law constant (kH) for carbon monoxide in water at 25°C is 9.71×10-4 mol/L·atm. How many grams of CO will dissolve in
Olegator [25]

Answer: 0.0748 grams of CO will dissolve in 1.00 L of water if the partial pressure of CO is 2.75 atm

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

C_{CO}=K_H\times p_{liquid}

where,

K_H = Henry's constant = 9.71\times 10^{-4}mol/L.atm

p_{CO} = partial pressure of CO = 2.75 atm

Putting values in above equation, we get:

C_{CO}=9.71\times 10^{-4}mol/L.atm\times 2.75atm\\\\C_{CO}=2.67\times 10^{-3}mol/L

C_{CO}=2.67\times 10^{-3}mol/L\times 28g/mol=0.0748g/L

Hence, the solubility of carbon monoxide gas is 0.0748 g/L

Why do birds have hollow bones​
Minchanka [31]

Hollow \:  bones  \: are \:  also \:  called  \\ pneumatized  \: bones, \:  meaning \:  they're  \: filled  \\ with \:  space \:  for  \: air. \:  It \\  is \:  thought  \: that  \: this  \: structure \\  helps \:  with  \: oxygen  \: intake \:  during  \\ flight.  \: Air \:  sacs \:  are \:  attached  \: to \\  the \:  hollow \:  areas \:  in  \: a  \: bird's  \: bones. ... \\  This \:  adds  \: more  \: oxygen \:  to \\  the \:  blood, \:  providing \:  a \\  bird \: with \:extra \:energy \:for\: flight.
