Hey there!:

Gas chromatography (GC) is a type of chromatography used for separating compounds that can be vaporized without decomposition. The sample to be analyzed must be able to be vaporized in the system inlet.

So, the correct answer is A.

Hope this thelps!

Illusion [34]

Answer:

A. Reference blank

B. Cuvettes

C. Transmittance

D. Absorbance

E. Wavelength

Explanation:

A reference blank is a sample prepared using the solvent and any other chemicals in the sample solutions, but not the absorbing substance.

A square-shaped container, typically made of quartz, designed to hold samples in a spectrophotometer is known as Cuvettes.

A measurement of the amount of light that passes through a sample or percentage of light transmitted by the sample, with the respective intensities of the incident and transmitted beams is called Transmittance.

The measurement of the amount of light taken in by a sample is known as Absorbance

The wavelength is also the distance travelled by the wave during a period of oscillation. In spectrophotometry, the unit is inversely proportional to energy and commonly measured in nanometers

Assuming the reaction is at STP if 2.25 moles of Li are exposed to 3.25 moles of water, which is the limiting reactant?
crimeas [40]

Answer: Lithium

Explanation:

The ratio for the reaction of Li and water is the same, but there are more moles of water than lithium. Therefore, lithium is the limiting reactant.

A helium balloon contains 0.40 g of helium. given the molecular weight of helium is 4.0 g/mol, how many moles of helium does it
Rasek [7]

Answer is 0.10 mol.


<em>Explanation;</em>


n = m/M


Where n is number of moles (mol), m is the mass of substance (g) and M is the molar mass of the substance (g/mol).


n = ?

m = 0.40 g

M = 4.0 g/mol


From substitution,

n = 0.40 g /4.0 g/mol

n = 0.10 mol


Hence, the balloon has 0.10 mol of He.
