<u>Answer:</u> The value of equilibrium constant, 
for the given reaction is 12.85.
<u>Explanation:</u>
For the given chemical equation:
At t = 0 0.350M 0.650M 0.300M
At 
(0.350 - x) (0.650 - 2x) (0.300 + x)
We are given:
Equilibrium concentration of A = 0.220 M
Forming an equation for concentration of A at equilibrium:
Thus, the concentration of B at equilibrium becomes = 
Equilibrium concentration of C = 0.430 M
The expression of for the given chemical equation is:
![K_c=\frac{[C]}{[A][B]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BC%5D%7D%7B%5BA%5D%5BB%5D%5E2%7D)
Putting values in above equation:
Hence, the value of equilibrium constant, for the given reaction is 12.85.
Answer:
Thomson's results showed that atoms contain smaller particles, so Dalton's theory had to be modified. Rutherford's results showed that most of an atom is empty space and that the mass is concentrated in the center of the atom.

<span>The right answer is D. In a situation where the sound wave reaches the ear and the reflected wave reaches the ear less than 0.1 seconds later, the individual would not be able to hear an echo. There needs to a far more significant delay between the sound and the reflection of said sound reaching the listener's ear for the echo effect to become apparent.</span>

Answer:
4050 mL
Explanation:
Given data:
Mass of glucose = 150.1 g
Molarity of solution = 0.205 M
Volume of solution = ?
Solution:
Molarity = number of moles of solute / L of solution.
Now we will calculate the moles of sugar first.
Number of moles = mass/ molar mass
Number of moles = 150.1 g/ 180.156 g/mol
Number of moles = 0.83 mol
Now we will determine the volume:
Molarity = number of moles of solute / L of solution.
0.205 M = 0.83 mol / L of solution.
L of solution = 0.83 mol / 0.205 M
L of solution = 4.05 L
L to mL conversion:
4.05 L × 1000 mL / 1 L = 4050 mL
