Solvation describes the interaction of solvent with dissolved molecules.
Answer:
Empirical formula is C₂H₆O.
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of atoms of different elements in small whole number
Given data:
Percentage of hydrogen = 13.3%
Percentage of carbon = 52.0%
Percentage of oxygen = 34.7%
Empirical formula = ?
Molecular formula = ?
Solution:
Number of gram atoms of H = 13.3 / 1.01 = 13
.17
Number of gram atoms of O = 34.7 / 16 = 2.17
Number of gram atoms of C = 52.0 / 12 = 4.3
Atomic ratio:
C : H : O
4.3/2.17 : 13.17/2.17 : 2.17/2.17
2 : 6 : 1
C : H : O = 2 : 6 : 1
Empirical formula is C₂H₆O.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 46 / 158
The relative molecular mass of compound is not correct.
The heat change is related to specific heat as
Heat change = mass of substance X specific heat X change in temperature
So if we are considering same amount of substance
and we are starting with the same temperature
the change in temperature will be inversely proportional to the specific heat
higher the specific heat lower the temperature change
Thus the change in temperature will be least for the substance with highest specific heat.
