<u>Answer</u>:
A precipitation is said to be complete precipitation when no further precipitate can be formed in the process.
<u>Explanation</u>:
Precipitation is the reaction of creating solid from the solution. In precipitation reactions, insoluble salts are formed when two solutions containing soluble salts are combined.
These two solutions contain different salts and have either cation or anion pairing. This reaction helps in the determination of ions in a solution. The solubility table is being used to predict the precipitation reaction. It occurs in solid when one solid’s concentration is above solubility.
4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.
<h3>What are Noble Gases ?</h3>
The noble gases are helium, argon, krypton, xenon, and radon, in order of their mass.
They are called noble gases because they are so majestic that they do not react with anything in general.
The work done can be calculated by the formula
Q=n Cp ΔT
Cp= ( 1+ f/2)R
R= 8.3144598 J. mol-1.
Cp = (1+3/2) * 8.314
Cp = 5*8.314/2
Q= 2 * 5 *8.314 *100/2
Q = 4157 J
Therefore 4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.
