Step-by-step explanation:</h3>
<u>Step 1: Define</u>
[RxN] 2NO₂ ⇆ N₂O₄
[Equilibrium Rate Law] ![\displaystyle K_c = \frac{[N_2O_4]}{[NO_2]^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20K_c%20%3D%20%5Cfrac%7B%5BN_2O_4%5D%7D%7B%5BNO_2%5D%5E2%7D)
NO₂ = 11.95 M
N₂O₄ = 6.05 M
<u>Step 2: Find K</u>
- Substitute [ERL]:
![\displaystyle K_c = \frac{[6.05]}{[11.95]^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20K_c%20%3D%20%5Cfrac%7B%5B6.05%5D%7D%7B%5B11.95%5D%5E2%7D)
- Exponents:
![\displaystyle K_c = \frac{[6.05]}{[142.803]}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20K_c%20%3D%20%5Cfrac%7B%5B6.05%5D%7D%7B%5B142.803%5D%7D)
- Divide:
- Round (Sig Figs):
This value of K tells us that the reactants are favored in the equilibrium reaction (K < 0.1).
Answer:
15
Step-by-step explanation:
The formula for factoring a sum of cubes is:
We have a=3f and b=5g here.
So a*b in this case is 3f*5g=15fg.
The ? is 15.
Sound travels 10200m farther through stone in 17 seconds than through aluminium
Speed of sound in aluminium = 3100 m/s
The speed of sound in stone = 3700 m/s
Time taken = 17 minutes
Distance traveled = Speed x Time
Distance traveled by sound in aluminium in 17 seconds = 3100 x 17
Distance traveled by sound in aluminium in 17 seconds = 52700 m
Distance traveled by sound in stone in 17 seconds = 3700 x 17
Distance traveled by sound in stone in 17 seconds = 62900 m
Difference in the distance traveled = 62900 - 52700
Difference in the distance traveled = 10200 m
Sound travels 10200m farther through stone in 17 seconds than through aluminium
