Answer:
the volume of 50.2 grams of co2
would simply be
50.2÷48
Answer:
equilibrium will shift to the right, and more NH3 will be formed
Explanation:
N2(g) + 3H2(g) ---> 2NH3(g)
1 mol +3 mol 2 mol
4 mol 2 mol
When we increase the pressure, the pressure will try to restore old value, so it has to become lower. Pressure is lower when number of particles is less
4 <2, so equilibrium will shift to the right, and more NH3 will be formed.

Answer:
Momentum = (mass) x (speed)
Mass is constant, so the rate of change of momentum is
(mass) x (rate of change of speed) .
But (rate of change of speed ) is just acceleration.
So the rate of change of momentum is (mass) x (acceleration).
But (mass) x (acceleration) is Force.
So Force is the rate of change of momentum. Verrrrrrrry interesting !
In this problem, Force = (40 kg) x (9 m/s²) = 360 newtons.
One 'Newton' is one kilogram-meter per second² .
Unit of momentum is (kilogram)-(meter per second), so 'newton'
is also a unit of time rate of change of momentum.
Rate of change of momentum is 360 momentum units per second.
