The balanced chemical reaction is written as:
<span>3NO2 + H2O = 2HNO3 + NO
Assuming that the gases in this reaction are ideal gas, then we can use the conversion from L to moles which is 1 mol of ideal gas is equal to 22.4 L. We calculate as follows:
538 L NO2 ( 1 mol / 22.4L ) ( 1 mol NO / 3 mol NO2 ) ( 22.4 L / 1 mol ) = 179.33 L NO is produced</span>
Answer:
An element is a pure substance as well, because if we fill up a balloon with just helium gas ,it will only contain helium atoms
A physical change that may happen in a movie theater is:
You accidentally step on a piece of popcorn.
That piece of popcorn is still made up of the same things but LOOKS different. Therefore, the piece of popcorn went through a physical change.
I hope this helps!
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
