Answer:
1.125 moles of hydrogen are needed.
Explanation:
Given data:
Number of moles of ammonia formed = 0.75 mol
Number of moles of hydrogen needed = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of ammonia and hydrogen.
NH₃ : H₂
2 : 3
0.75 : 3/2×0.75 = 1.125 mol
1.125 moles of hydrogen are needed.
The question doesn’t make sense sorry
The answer is D because the box b's force to the left is not being cancelled out and box d's force is trying to be cancelled out, but he has more force going up then down so he is moving up
Answer:
The phosphorus ylide reacts with the aldehyde or ketone to make an oxaphosphetane.
Explanation:
The Wittig reaction is a reaction that occurs between a phosphorus ylide and an aldehyde or ketone. The final products are an alkene and triphenyl phosphine oxide.
The first step in the reaction is the attack of the phosphorus ylide on the aldehyde or ketone. This is followed by attack of oxygen on phosphorus to form a [2+2] cycloaddition product (oxaphosphetane) which decomposes to form the alkene and triphenylphosphine oxide.
