Answer:
B
Explanation:
momentum = mass (kg) x velocity (m/s²)
Answer : The partial pressure of
is, 67.009 atm
Solution : Given,
Partial pressure of
at equilibrium = 30.6 atm
Partial pressure of
at equilibrium = 13.9 atm
Equilibrium constant = 
The given balanced equilibrium reaction is,

The expression of
will be,

Now put all the values of partial pressure, we get


Therefore, the partial pressure of
is, 67.009 atm
Answer:
The magnitude of the angular acceleration ∝ =
}[/tex]
Explanation:
The angular acceleration ∝ is equal to the torque (radius multiplied by force) divided by the mass times the square of the radius. The magnitude of angular acceleration ∝ will have the equation above but we have to replace the mass in the equation by 2.8kg as stated.
Ba(NO₃)₂ + Na₂SO₄ → BaSO₄ + NaNO₃
By Trial and error.
Ba(NO₃)₂ + Na₂SO₄ → BaSO₄ + 2NaNO₃
Check:
LHS RHS
Ba 1 1
N 2 2
S 1 1
O 3*2 + 4 = 10 4 + 2*3 = 10
Answer:
the unbalanced force
Explanation:
An unbalance forces are defined as the forces which causes a change in the speed or velocity of a moving object. A force causes a change in the motion of a body and an unbalanced force causes the body to change its velocity and speed or a change in its direction.
An unbalanced force will start movement in a static object or it can cause to speed up the moving object or it can cause to stop the moving object.
Thus an unbalanced force causes the cart to speed up.
