The answer to your question is nitrogen dioxide
Evaporation technique is used to separate a compound dissolved in a solvent by vaporizing the solvent and converting it to gaseous state. This leaves behind the solid residue present in the solution after the pure solvent is vaporized. The solvent vapors can be collected and condensed to get pure solvent. But the solid residue cannot be considered pure as it is the left over solid after all the solvent is evaporated. If the solution has some impurities, the solid left over includes all of the impurities. So, we cannot obtain a pure solid in evaporation technique.
Answer:
to see what will work with that temp
Explanation:
Density= 5m^3
Explanation:
Here, the Mass of an object is 25g
To convert grams into kilograms, we need to divide 25 by 1000
so, the 25g=25/1000 = 0.025kg.
The volume of an object is given by 5cm^3 ( cubic centimetre)
To convert cubic centimetre to meter cube, we need to divide 5 by 1000.
So, 5cm^3=5/1000=0.005m^3
Finally, the equation of density is
DENSITY= MASS/VOLUME
Density = 0.025/0.005
= 5m^3
Hence, the density of the object is 5m^3.
