Answer:
Velocity
Explanation:
In the context of speed, this refers to the change of position in a fixed amount of time, and velocity provides more depth to that; it also gives direction, which makes sense when you eventually learn that the velocity is the derivative of the position.
In physics, velocity is prevalently used.
Molar Mass of Fe₂O₃ = <span>159.69 g/mol
As we know,</span>
Moles = Mass / M.mass
Solving for Mass,
Mass = Moles × M.mass
Putting Values,
Mass = 0.50 mol ×159.69 g/mol
Mass = 79.84 g
Answer:
The rate at which ammonia is being produced is 0.41 kg/sec.
Explanation:
Haber reaction
Volume of dinitrogen consumed in a second = 505 L
Temperature at which reaction is carried out,T= 172°C = 445.15 K
Pressure at which reaction is carried out, P = 0.88 atm
Let the moles of dinitrogen be n.
Using an Ideal gas equation:
According to reaction , 1 mol of ditnitrogen gas produces 2 moles of ammonia.
Then 12.1597 mol of dinitrogen will produce :
of ammonia
Mass of 24.3194 moles of ammonia =24.3194 mol × 17 g/mol
=413.43 g=0.41343 kg ≈ 0.41 kg
505 L of dinitrogen are consumed in 1 second to produce 0.41 kg of ammonia in 1 second. So the rate at which ammonia is being produced is 0.41 kg/sec.
Answer:
.0068
Explanation:
You divided the number of molecules by 6.022*10^23 (Avagodros Number) to get the number of moles.
