If we use the equation:
N2 + 3H2 --> 2NH3
Then
1 mol of Nitrogen required 3 moles of Hydrogen
x mols : 6.34mols
X = 6.34/3
X = 2.11 moles of Nitrogen are required.
Oh wow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer: 4.2 m
Explanation:
The time taken by the tennis ball to cover vertical displacement 1.30 m would be the same time in which ball would cover horizontal distance.
Initial velocity of the ball, u = 8.08 m/s in horizontal direction.
Initial velocity in the vertical direction is 0.
consider upward direction as positive and downward direction as negative. The ball free falls under gravity in the vertical direction.
Using the second equation of motion,
y = u t + 0.5 at²
⇒-1.30 m = 0 + 0.5 ×(-9.8m/s²) t²
⇒t = 0.52 s
There is no external force acting in the horizontal direction, thus horizontal distance covered is:
s = u t ⇒ s = 8.08 m/s × 0.52 s = 4.2 m
Thus, the tennis ball lands 4.2 m far away.
Answer:
Explanation:
1.) 
2.) COP
3.) Rate of heat absorption
COP
Therefore, cooling in minutes=
COP cannot cycle= 
Rate of heat absorption 
cooling time in minutes with cannot cycle
You need to know the water pressure and how deep the water
