Some analytes must be derivatized to increase their column retention or detectability. Derivatization means Group of answer choi
posledela

Derivatization means adding fluorescent labels or combining the analyte with chiral reagents or other chemicals to increase detectability.

Some analytes must be derivatized to increase their column retention or detectability.

Retention time can be referred to as the amount of time a solute spends in the stationary and mobile phases of a column.

Detectability is the ability of an analyte to get detected in the mobile phase of chromatography.

The refractometer, fluorescence detector, and UV detector are the three most popular liquid chromatography detectors. These detectors increase the detectability.

For derivatization, the fluorescence detector are used.

Brut [27]

Answer:

-205.7kj

Explanation:

Now adding reaction 2 and twice of reaction 3 and reverse of reaction 1, we get the enthalpy of the reaction.

The expression for enthalpy for the following reaction will be,

where,

n = number of moles

Now put all the given values in the above expression, we get:

Therefore, the enthalpy of the following reaction is,  -205.7kj

For the reaction 6 Li + N2 → 2 Li3N , what is the maximum amount of Li3N (34.8297 g/mol) which could be formed from 14.18 mol (6
Yuki888 [10]
Moles Li = 3.50 g / 6.941 g/mol= 0.504
the ratio between Li and N2 is 6 : 1
moles N2 required = 0.504 /6=0.0840
we have 3.50 g / 28.0134 g/mol=0.125 moles of N2 so N2 is in excess
the ratio between Li and Li3N is 6 : 2
moles Li3N = 0.504 x 2 /6=0.168
mass Li3N = 0.168 mol x 34.8297 g/mol=5.85 g
