B. climate
this is because it influences the speed of chemical reactions in the soil
Explanation:
Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These changes add more greenhouse gases in our atmosphere and this causes climate change.
Answer:
<h3>The answer is 0 kgm/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 1000 kg
Since the car is sitting at rest it has no velocity that's
velocity = 0 m/s
So we have
momentum = 1000 × 0
We have the final answer as
<h3>0 kgm/s</h3>
Hope this helps you
Answer:
The correct answer is 0.024 M
Explanation:
First we use an ICE table:
Br₂(g) + F₂(g) ⇔ 2 BrF(g)
I 0.111 M 0.111 M 0
C -x -x 2 x
E 0.111 -x 0.111-x 2x
Then, we replace the concentrations of reactants and products in the Kc expression as follows:
Kc= ![\frac{[BrF ]^{2} }{[ F_{2} ][Br_{2} ]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BBrF%20%5D%5E%7B2%7D%20%7D%7B%5B%20F_%7B2%7D%20%5D%5BBr_%7B2%7D%20%20%5D%7D)
Kc= 
54.7= 
We can take the square root of each side of the equation and we obtain:
7.395= 
0.111(7.395) - 7.395x= 2x
0.82 - 7.395x= 2x
0.82= 2x + 7.395x
⇒ x= 0.087
From the x value we can obtain the concentrations in the equilibrium:
[F₂]= [Br₂]= 0.111 -x= 0.111 - 0.087= 0.024 M
[BrF]= 2x= 2 x (0.087)= 0.174 M
So, the concentration of fluorine (F₂) at equilibrium is 0.024 M.
