Answer:
4s.
Explanation:
Hello,
In this case, considering that the instantaneous acceleration is computed via the change in the velocity divided by the change in the time, at 4 s we can evidence that the instantaneous acceleration is -2m/s² since the initial velocity at t=0s is 8m/s and at t=4s the velocity is 0 m/s, meaning that such decrease accounts for a deceleration process which is represented by a negative acceleration, and the value is:
Best regards.
The answer a boulder has more mass and stuff like that.
your answer will be D Strong nuclear force is most like electric because they are both related to distance.
Answer: A and B
Explanation: it says benefits and the other two are not benefits.
The complete question is as follows: At 700 K, decomposes to carbon and chlorine. The Kp for the decomposition is 0.76.
Find the starting pressure of at this temperature that will produce a total pressure of 1.1 atm at equilibrium.
Answer: The starting pressure of is 0.79 atm.
Explanation:
The equation for decomposition of is as follows.
Let us assume that initial concentration of is 'a'. Hence, the initial and equilibrium concentrations will be as follows.
Initial: a 0 0
Equilibrium: (a - x) 0 2x
Total pressure = (a - x) + 2x = a + x
As it is given that the total pressure is 1.1 atm.
So, a + x = 1.1
a = 1.1 - x
Now, expression for equilibrium constant for this equation is as follows.
Hence, the value of 'a' is calculated as follows.
a + x = 1.1 atm
a = 1.1 atm - x
= 1.1 atm - 0.31 atm
= 0.79 atm
Thus, we can conclude that starting pressure of is 0.79 atm.
