Answer: The key difference between dissociation and solvation is that dissociation is the breakdown of a substance into the atoms or ions from which the substance is made of whereas solvation is the dissolution of a substance in a solvent due to the attraction forces between the solvent molecules.
Answer:
The egg is changed from liquid to soli
Explanation:
The law of conservation of mass states that "Matter/mass can neither be created nor destroyed but can be converted from one form to another".
Inside of the Egg is liquid in nature and during the process of cooking the egg the liquid changes to solid.

Answer:
1.2 g
Explanation:
Data Given:
mass of Ag = 3.98 g
mass of Cu = ?
Reaction Given:
Cu + 2AgNO₃ --------→ Cu(NO₃)₂ + 2Ag
Solution:
To solve this problem we have to look at the reaction
Reaction:
Cu + 2AgNO₃ --------→ Cu(NO₃)₂ + 2Ag
1 mol 2 mol
from reaction we come to know that 1 mole of Cu give 2 moles of Ag
Now Convert moles to mass
Molar mass of Cu = 63.5 g/mol
Molar mass of Ag = 107.9 g/mol
So,
Cu + 2 AgNO₃ --------→ Cu(NO₃)₂ + 2Ag
1 mol (63.5 g/mol) 2 mol ( 107.9g/mol)
63.5 g 215.8 g
So if we look at the reaction 63.5 g of Cu gives 215.8 g of Ag, then how many g of Cu will be Produce by 3.98 g of Ag
For this apply unity formula
63.5 g of Cu ≅ 215.8 g of Ag
X g of Cu ≅ 3.98 g of Ag
By Doing cross multiplication
mass of Cu = 3.98 g x 63.6 g / 215 g
mass of Cu = 1.2 g
1.2 g of Cu will produce 3.98 g of Ag
