The answer is 4H2O good luck
Answer:
Dispersion system is a system in which certain particles are scattered in a continuous liquid or solid medium. The two phases present in this system are the dispersed particles and dispersion medium. These phases may or may not be present in the same state.
In a dispersion system, the particles that are dispersed are known as the dispersed particles and the medium in which the particles are dispersed is known as the dispersion medium.
Answer:
The correct answer is option D.
Explanation:
All the cations given belong to the group-1 cation and will give precipitate of their respective chlorides when HCl is added to their aqueous solution.
All the precipitates are insoluble in cold water but out of all these only lead(II) chloride is soluble in warm water.
If the reacted oxygen is 35.1 g.
H2O mass= (35.1+9.8)-29.6
= 19.3g
The molar specific heat Cv = R s / 2
70.6 J/mol.K = (8.314 J/mol.K) * s / 2
So the number of degrees of freedom are:
s = 16.98 = 17
