Answer:
The reactive nucleophile is Ketone.
Explanation:
In organic chemistry, The process of acid - catalyzed aldol condensation starts from when ketone (or any aldehyde) is converted to an -enol, after which it attacks another ketone/aldehyde that has already been activated by parbonyl oxygen protonation.
The process of this is that first of all the ketone undergoes tautomerization to form -enol. Thereafter, the other carbonyl will undergo protonation which makes the carbon activated towards attack. Now, the nucleophilic enol will be added to the carbonyl in a [1,2]-addition reaction and we will now use deprotonation to obtain the neutral Aldol product.
Now, since only the ketone can produce an -enol, thus it is the nucleophile as aldehydes are better electrophiles
Answer:
1. Hydrogen Iodide
2. 6 molecules of Hydrogen Iodide
3. Iodine is the limiting reagent
Explanation:
The image of the illustration in the question has been attached:
1. The illustration represents a mixture of hydrogen ( light blue ) and iodine ( purple )
H₂ + I₂ ---> 2HI
This forms hydrogen iodide.
2. In the given illustration, 6 product molecules of Hydrogen Iodide. This is indicated in the box on the right side of the illustration.
3. The limiting reagent is the reactant that determines how much of the products are made. It is the substance that is totally consumed when the chemical reaction is completed. In the box on the right side of the illustration, you will see that hydrogen which is indicated by blue is in excess. The limiting reagent is the one that is completely consumed which is the iodine.

Answer:</h3>
2.5 moles
<h3>
Explanation:</h3>
<u>We are given;</u>
We are required to determine the number of moles of sodium.
- We know that, 1 mole of an element contains a number of atoms equivalent to the Avogadro's number, 6.022 × 10^23.
- That is, 1 mole of an element = 6.022 × 10^23 atoms.
Therefore;
1 mole of sodium contains 6.022 × 10^23 atoms
To get the number of moles;
= Number of atoms ÷ Avogadro's number
= 1.5 × 10^24 atoms ÷ 6.022 × 10^23 atoms/mol
= 2.49 moles
= 2.5 moles
Therefore, 2.5 moles of sodium contains 1.50 × 10^24 sodium atoms
Answer:
Nitrogen is inert because its p-subshell is half-filled due to it has maximum exchange energy. Thus it is exists in stable form as like inert gas and it form triple bond (N≡N). N2 molecules is very stable and its dissociation energy is 225kcal/mol.
