Answer:
A. K = 59.5
Explanation:
Hello there!
In this case, since this reaction seems to start moving leftwards due to the fact that neither A nor Y are present at equilibrium, we should rewrite the equation:
3C (g) + D (g) <-- --> 2A (g) + Y (g)
Thus, the equilibrium expression is:
![K^{left}=\frac{[A]^2[Y]}{[C]^3[D]}](https://tex.z-dn.net/?f=K%5E%7Bleft%7D%3D%5Cfrac%7B%5BA%5D%5E2%5BY%5D%7D%7B%5BC%5D%5E3%5BD%5D%7D)
Next, according to an ICE table for this reaction, we find that:
![[A]=2x](https://tex.z-dn.net/?f=%5BA%5D%3D2x)
![[Y]=x](https://tex.z-dn.net/?f=%5BY%5D%3Dx)
![[C]=0.651M-3x](https://tex.z-dn.net/?f=%5BC%5D%3D0.651M-3x)
![[D]=0.754M-x](https://tex.z-dn.net/?f=%5BD%5D%3D0.754M-x)
Whereas x is calculated by knowing that the [C] at equilibrium is 0.456M; thus:
Next, we compute the rest of the concentrations:
![[A]=2(0.065M)=0.13M](https://tex.z-dn.net/?f=%5BA%5D%3D2%280.065M%29%3D0.13M)
![[Y]=0.065M](https://tex.z-dn.net/?f=%5BY%5D%3D0.065M)
![[D]=0.754M-0.065M=0.689M](https://tex.z-dn.net/?f=%5BD%5D%3D0.754M-0.065M%3D0.689M)
Thus, the equilibrium constant for the leftwards reaction is:
Nonetheless, we need the equilibrium reaction for the rightwards reaction; thus, we take the inverse to get:
Therefore, the answer would be A. K = 59.5.

Answer:
Equal
Explanation:
According to Newton's third law of motion, the strength of a reaction is equal and opposite to the strength of the action force.
- Newton's third law of motion states that "action and reaction forces are equal in magnitude but opposite in direction".
- Therefore, if an object exerts a force of magnitude KN on a body.
- The body will in return exert the same amount of force back on the object.
- The law gives us an idea that force is paired in their action.
Answer:
Rachel needs 0.52 kg of fertilizer.
Explanation:
Since the surface is a <em>square</em> of 10 ft of size its area is A = 10 ft x 10 ft = 1.0 x 10² ft². <em>One third</em> of that space is devoted to tomatoes (<em>"space is divided equally among tomatoes, lettuce, and strawberries"</em>), that is, 1/3 x 100 ft² = 33 ft².
We calculate the kilograms of fertilizer required we need to know 2 equivalences:
1 ac = 43,560 ft²
1 lb = 0.4535 kg
Then, we can use proportions to find out the amount of fertilizer used:
Answer: a
Explanation: because an Arrhenius acid is a compound that increases the H + ion concentration in aqueous solution. An Arrhenius base is a compound that increases the OH − ion concentration in aqueous solution.
