Why is water not used as a solvent in paper chromatography​

Chemistry
2 answers:
bogdanovich [222]4 years ago

Answer:

Because the kind of compounds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.

What is happening to the particles in a substance during evaporation?
AysviL [449]
During evaporation, liquid particles on the surface momentarily gain enough energy due to random thermal motion to overcome the intermolecular attractions and escape into the gas phase. These evaporating particles, by virtue of gaining energy, also increase in velocity.

Thus, the correct answer here would be the third choice.

It requires 2,500 joules to raise a certain amount of water (c = 4.186 j/g°c) from 20.0°c to 60.0°c. what is the mass of the wat
Bogdan [553]

Answer:

15 grams of water will absorb 2,500 Joules  in going from 20.0 to 60.0 C.

Explanation:

The heat involved in raising a mass (m) of a substance with a specific heat (c) from one temperature to another (Delta T) is given by:

Heat = mc(Delta T)

2,500 Joules = m*(4.186J/gC)*(60C-20C)

2,500 Joules = m*(4.186J/gC)*(40C)

2,500 Joules = m*(4.186J/gC)*(40C)

m = (2,500J)/(4.186*40J/g)

m = 14.93 grams
