Answer:
The main products obtained from complete hydrolysis of a ketal are ketone (90%) and hydrate (10%), we also obtained as byproducts two alcohols (ROH and R
OH). See attached image
Explanation:
To understand this question, one has to know what a ketal is and also what is complete hydrolysis.
Ketal: functional group present in organic chemistry that has a central carbon attached to 2 R groups and 2 OR.
Hydrolysis: reaction of water with a molecule
We can observe in the diagram that this reaction is found in equilibrium, meaning that depending on the concentration of the diverse substrates and products, the reaction will favor the direction towards one or the other.
Note: In the last part of the reaction we can observe that the equilibrium favors the production of ketone over that of a hydrate. This occurs since a ketone is more stable than that of a hydrate (about 90% will be ketone while 10% will be a hydrate).

4.75 is the equilibrium constant for the reaction.
Answer:
1.02mole
Explanation:
The reaction equation is given as:
2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
Given:
Mass of H₂SO₄ = 50g
Unknown:
Number of moles of NaOH = ?
Solution:
To solve this problem, we first find the number of moles of the acid given;
Number of moles =
Molar mass of H₂SO₄ = 2(1) + 32 + 4(16) = 98g/mol
Now;
Number of moles = = 0.51mole
From the balanced reaction equation:
1 mole of H₂SO₄ will be neutralized by 2 mole of NaOH
0.51 mole of H₂SO₄ will be neutralized by 2 x 0.51 = 1.02mole of NaOH
