Answer:
Option D is correct = 58 g
Explanation:
Data Given:
mass of LiOH = 120 g
Mass of Li3N= ?
Solution:
To solve this problem we have to look at the reaction
Reaction:
Li₃N (s) + 3H₂0 (l) -----------► NH₃ (g) + 3LiOH (l)
1 mol 3 mol
Convert moles to mass
Molar mass of LiOH = 24 g/mol
Molar mass of Li₃N = 35 g/mol
So,
Li₃N (s) + 3H₂0 (l) -----------► NH₃ (g) + 3LiOH (l)
1 mol (35 g/mol) 3 mol (24 g/mol)
35 g 72 g
So if we look at the reaction 35 g of Li₃N react with water and produces 72 g of LiOH , then how many g of Li₃N will be react to Produce by 120 g of LiOH
For this apply unity formula
35 g of Li₃N ≅ 72 g of LiOH
X of Li₃N ≅ 120 g of LiOH
By Doing cross multiplication
Mass of Li₃N = 35 g x 120 g / 72 g
mass of Li₃N = 58 g
120 g of LiOH will produce from 58 g of Li₃N
So,
Option D is correct = 58 g
Any polar substances because water is polar and like dissolves in like
Answer:
Hydrogen Bonding
Explanation:
Hydrogen bonding occurs between the positive dipole of one water molecule with the negative dipole of another. It is an intermolecular force that gives water its unique properties such as: high boiling point, high specific heat, cohesion, adhesion, and density.
(CH3)3N + H2O ---> (CH3)3NH+ + OH-
The equation of Kb:
Kb = [(CH3)3NH+][OH-]/[(CH3)3N]
<h3>
What do we know about the process of dissolution?</h3>
A solute can dissolve in a solvent in a solid, liquid, or gaseous phase to create a solution through the process of dissolution. Solubility. The greatest amount of a solute that may dissolve in a solvent at a particular temperature is known as its solubility. The solution is said to as saturated when the maximum amount of solute is present.
Several variables influence solubility, including:
- The solute's concentration
- The system's temperature
- Pressure (for gases in solution)
- The solvent's and solute's polarity
