Answer:-
b. compound b will show an nh absorption while compound a will not.
Explanation:-
For compound B CH3CH2CH2NH2 there are two N-H bonds present. So it will show NH absorption.
But in compound A CH3CH2CH2N(CH3)2 there are no N-H bonds. So it will not show NH absorption.
Answer: a) . Ammonia is the limiting reagent
b. Oxygen is left over and 0.1375 g of oxygen is left over.
c. The theoretical yield of is 35.29 g.
d. The theoretical yield of is 31.74 g.
Explanation:
To calculate the number of moles, we use the equation:
For
Given mass of ammonia = 20.0 g
Molar mass of ammonia = 17.031 g/mol
Putting values in equation 1, we get:
For
Given mass of oxygen gas = 50.0 g
Molar mass of oxygen gas = 32 g/mol
Putting values in equation 1, we get:
The chemical equation for the reaction is
By Stoichiometry of the reaction:
4 moles of ammonia reacts with = 5 moles of oxygen
So 1.17 moles of ammonia will react with = of oxygen
As, given amount of oxygen is more than the required amount. So, it is considered as an excess reagent and (1.6-1.4625)= 0.1375 g of oxygen is left unreacted.
Thus ammonia is considered as a limiting reagent because it limits the formation of product.
1. By Stoichiometry of the reaction:
4 moles of ammonia produces = 4 moles of
1.17 moles of ammonia will produce = of
Mass of
Thus Theoretical yield of is 35.29 grams.
2. By Stoichiometry of the reaction:
4 moles of ammonia produces = 6 moles of
1.2 moles of ammonia will produce = of
Mass of
Thus Theoretical yield of is 31.74 grams.
