In this equilibrium, hydroxide ion acts as a A) Lewis base B) Bronsted base C) both A & B D) neither A or B
1 answer:
Answer:
(b) Bronsted base
Explanation:
The hydroxide ion is formed when losses
ion
We know hat the compound which losses is known as the bronsted acid and the ion which is formed after losing
is known as bronsted base
As the hydroxide ion is formed after losing the hydrogen ion from so it is a bronsted base.

0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.
Define the molarity of a solution.
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
Volume of solution = 911 mL=0.911L
Given the mass of MgS = 29.9 g
Molar mass of MgS = 56.38 g/mol
Moles of MgS = 0.5303299042
Molality = 0.5821403998=0.58
Hence, 0.58 is the molarity of 29.9 g of MgS in 911 mL of solution.
