Answer:
Ernest Z. The molarity and mass percent of the vinegar are 0.8393 mol/L and 5.010 %.
Answer:
Less than 0.033 M:
![[Z]_{eq}=2.4x10^{-3}M](https://tex.z-dn.net/?f=%5BZ%5D_%7Beq%7D%3D2.4x10%5E%7B-3%7DM)
Explanation:
Hello,
In this case, the described equilibrium is:
Thus, the law of mass action is:
![K=\frac{[Z]^2}{[A]^2[B]}=0.43](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BZ%5D%5E2%7D%7B%5BA%5D%5E2%5BB%5D%7D%3D0.43)
Nevertheless, given the initial concentration of Z that is 0.033 M, we should invert the equilibrium since the reaction will move leftwards:
![\frac{1}{K}=\frac{[A]^2[B]}{[Z]^2}=\frac{1}{0.43}=2.33](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BK%7D%3D%5Cfrac%7B%5BA%5D%5E2%5BB%5D%7D%7B%5BZ%5D%5E2%7D%3D%5Cfrac%7B1%7D%7B0.43%7D%3D2.33)
Know, by introducing the change 
due to the reaction extent, we can write:
Which has the following solution:
But the correct solution is 
since the other solutions make the equilibrium concentration of Z negative which is not possible. In such a way, its concentration at equilibrium is:
![[Z]_{eq}=0.033M-2(0.0153M)](https://tex.z-dn.net/?f=%5BZ%5D_%7Beq%7D%3D0.033M-2%280.0153M%29)
Which is clearly less than 0.033 M since the addition of a product shift the reaction leftwards in order to reestablish equilibrium (Le Chatelier's principle).
Regards.
Answer:
Lead to Sulfur = 2 : 1
Explanation:
Given
Represent lead with L and Sulfur with S
L1 = 6.46g for S1 = 1 g
L2= 3.23g for S2 = 1 g
Required
Determine the simple whole number ratio of L to S
Divide L1 by L2
L = L1/L2
L = 6.46g/3.23g
L = 2
Divide S1 by S2
S = 1g/1g
S = 1
Represent L and S as a ratio:
L : S = 2 : 1
Hence, the required ratio of Lead to Sulfur is 2 to 1
Answer:
Horizontal lines that represent different climate zones are called latitude.
Explanation:
Latitude is the distance that exists between a point on the Earth's surface to the equator, counted by the degrees of its meridian. That is, it is the distance, measured in degrees, that exists between any parallel and the line of the Equator. The latitude of a point is measured to the North or South of the zero parallel and its value can vary between 0 ° from the equator to 90 ° N from the North pole or 90 ° from the South pole.
Climate is related to latitude because it sets the amount of solar energy that a given region or place receives. Places located at high latitudes (far from the Ecuador) receive less sunlight than places located at low latitudes (near the Equator). Thus, cities distant from the equator and close to the poles have a cold climate, while at low altitudes there are high temperatures and a hot or tropical climate.
