A vibrating string can create longitudinal waves as depicted in the animation below.
The answer is C) vibrations
Answer:
The concentrations of A, B, and C at equilibrium:
[A] = 0.0 M
[B] = 2.7 M
[C] = 2.4 M
Explanation:
Concentration of 1.80 mol of A in 1.00 L container :
![[A]=\frac{1.80 mol}{1.00 L}=1.80 M](https://tex.z-dn.net/?f=%5BA%5D%3D%5Cfrac%7B1.80%20mol%7D%7B1.00%20L%7D%3D1.80%20M)
Concentration of 3.90 mol of B in 1.00 L container :
![[B]=\frac{3.90 mol}{1.00 L}=3.90 M](https://tex.z-dn.net/?f=%5BB%5D%3D%5Cfrac%7B3.90%20mol%7D%7B1.00%20L%7D%3D3.90%20M)
Initially
1.80 M 3.90 M 0
At equilibrium
(1.80-3x)M (3.90-2x) 4x
The expression of an equilibrium constant is given by :
![K_c=\frac{[C]^4}{[A]^3[B]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BC%5D%5E4%7D%7B%5BA%5D%5E3%5BB%5D%5E2%7D)
Solving for x:
x = 0.600
The concentrations of A, B, and C at equilibrium:
[A] = [1.80-3x]=[1.80-3 × 0.600]= 0 M
[B] = [3.90-2x] = [3.90-2 × 0.600] = 2.7 M
[C] = [4x] =[4 × 0.600 M] = 2.4 M
Answer:
the humidity 80% at the temperature (20° C ) will have more water vapour because relative humidity is more at lesser temperature (20° C) and lower at higher temperature (40°C )

Answer:
substances with a higher boiling point are returning back to the flask which allows another substances with the specific context temperature (lower boiling point) to boil over and be purified.
Explanation:
The reason it happens because the lower boiling point substance vaporizes and crosses over while the other substance is waiting for its boiling point to reach
