Answer:
M
Explanation:
Equation for the reaction is as follows:
+
⇄ 
By Applying the ICE Table; we have
+
⇄ 
Initial x 0.0025 M 0.0010 M
Change 0 0 0
Equilibrium x 0.0025 M 0.0010 M
![K_c =\frac{[CO_2]^2}{[CO]^2[O_2]}](https://tex.z-dn.net/?f=K_c%20%3D%5Cfrac%7B%5BCO_2%5D%5E2%7D%7B%5BCO%5D%5E2%5BO_2%5D%7D)
Given that
; Then:






M
∴ The equilibrium concentration of CO =
M

You have 1 mol of silicon atoms. Therefore you have its atomic mass in grams. The answer is 28.055 g of silicon.
Answer:
The <em>C)</em> statement is true.
Explanation:
Let's call <em>
</em> the average for the first class and <em>
</em>the average for the second class. The overall average <em>x</em> is then:

Since the average is given by <em>
</em>. We can now calculate <em>x</em> assuming the maximun and minimun values of <em>
</em>, 2400 (which is 100 times 24) and 0 respectivly. That gives:

for it's maximun value and

for it's minimun value. So we get that <em>x</em> is between 36% and 93%.
