Answer:
4.13 moles of Fe.
Explanation:
Given data:
Moles of iron produced = ?
Moles of Fe₂O₃ = 3.5 mol
Moles of CO = 6.2 mol
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Now we will compare the moles of iron with CO and Fe₂O₃.
Fe₂O₃ : Fe
1 : 2
3.5 : 2/1×3.5 = 7 mol
CO : Fe
3 : 2
6.2 : 2/3×6.2 = 4.13 mol
The number of moles of iron produced by CO are less it will limiting reactant.
Thus, moles of iron formed in given reaction are 4.13 moles.
Given:
Sulfur dioxide and dihydrogen sulfide system
Vapor Pressure of water, H2O = 23 torr
P_SO2 = P_H2S
Temperature of the system = 298 K
Assume: Total pressure of the system is 1 atm = 760 torr
If partial pressure of SO2 is equal to the concentration of H2S, then,
760 = 0.5*PSO2 + 0.5PH2S
760 = PSO2

Answer:
A)coupling between 1H nuclei attached to adjacent C atoms.
Explanation:
The word ‘vicinal’ in chemistry means three bonds from the functional groups. The two functional groups are in a relationship with the atoms in adjacent position to them.
The 1H nuclei consists of two Hydrogen nucleus which acts as the functional groups. They are however attached and in a relationship with the adjacent C atoms. This makes option A the right choice.
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
