Estuary provides refuge after dam removal for bull trout
Bull trout use a bewildering array of strategies to aid in their survival, from remaining in streams their whole lives, like rainbow trout, to spending part of their lives in the ocean before returning to
streams to spawn, just as salmon do.
Bull trout are present in only one of two neighboring rivers in the Olympic peninsula, Washington state, and in this one (the Elwha River), where two large dams were removed. Dam removal resulted
in massive outflow of sediments, reducing the clarity of the water and also building up a large delta and expanding the size of the estuary at the mouth of the Elwha River.
Sampling for bull trout before, during, and after dam removal was used to detect whether bull trout changed their use of the Elwha River estuary or moved into the adjacent Salt Creek stream where
they were formerly absent. Sampling revealed no movement into Salt Creek, but numbers of bull trout in the Elwha River estuary increased greatly during and immediately after dam removal,
coinciding with large sediment outflow, before returning to their original low levels. Thus, bull trout appear to have used the enlarged estuary as a refuge from the effects of dam removal, then
returning to the river when the river water cleared up from the sediment
Of additional interest is the long-term response of bull trout to the additional habitat opened up above the former dams.

Using the balanced equation, The grams of \(Al_2O_3\) are produced from 0.85 moles of \(Al(OH)_3\) is 2(0.85) moles x 102 g/mole. The correct option is A.
To decide the quantity of \(Al_2O_3\) created from 0.85 moles of \(Al(OH)_3\) , we want to apply the stoichiometry of the balanced equation.
\(2 Al(OH)_3 --- > Al_2O_3 + 3 H_2O\)
From the equation, we will see that 2 moles of \(Al(OH)_3\) produce 1 mole of Al2O3.
To convert moles of \(Al(OH)_3\) to moles of \(Al_2O_3\) , we use the conversion factor:
1 mole \(Al_2O_3\) / 2 moles \(Al(OH)_3\)
Now we can calculate the moles of \(Al_2O_3\) made from 0.85 moles of \(Al(OH)_3\) :
Moles of \(Al_2O_3\) = 0.85 moles \(Al(OH)_3\) × (1 mole \(Al_2O_3\) / 2 moles \(Al(OH)_3\)
Moles of \(Al_2O_3\) = 0.85 moles \(Al(OH)_3\) / 2
Molar mass of \(Al_2O_3\) = (2 × atomic mass of Al) + (3 × atomic mass of O)
Molar mass of \(Al_2O_3\) = (2 × 27.0 g) + (3 × 16.0 g)
Molar mass of \(Al_2O_3\) = 54.0 g + 48.0 g
Molar mass of \(Al_2O_3\) = 102.0 g/mol
Mass of \(Al_2O_3\) = Moles of \(Al_2O_3\) × Molar mass of \(Al_2O_3\)
Mass of \(Al_2O_3\) = (0.85 moles \(Al(OH)_3\) / 2) × 102.0 g/mol
Mass of \(Al_2O_3\) = 0.425 moles × 102.0 g/mol
Mass of \(Al_2O_3\) = 43.35 g
Thus, the correct option is A.

A linear function is one in which the data points lie on a straight line. If you examine the data set, you'll notice that the slope is equal to 3, which means that for every increase of 1 in the x value, the y value increases by 3. The graph of this equation would be a straight line that goes upward. As the value of x increases, the value of y increases as well, and the two variables are proportional.
The relationship between x and y is thus linear. Therefore, in the given table, we notice a pattern that shows how the value of y is related to the value of x. As x increases, y also increases in a linear fashion, and we can calculate y by using the equation y=3x +1.

Round to FOUR decimal places.

Answer:
7.6997
Explanation:
Given :
X : ____7 ____ 15 ____ 28
P(X) __0.2 ___0.49 ____?
ΣP(x) = 1
0.2 + 0.49 + a = 1
a = 1 - 0.69
a = 0.31
Standard deviation = sqrt(Variance(x))
Variance = Var(X) = Σx²p(x) - E(x)²
E(x) = Σx*p(x) = (7*0.2) + (15*0.49) + (28*0.31) =
E(x) = 17.43
Σx²p(x) = (7^2 * 0.2) + (15^2 * 0.49) + (28^2 * 0.31) = 363.09
Var(X) = Σx²p(x) - E(x)²
Var(X) = 363.09 - 17.43^2
Var(X) = 363.09 - 303.8049
Var(X) = 59.2851
Standard deviation = sqrt(59.2851)
Standard deviation = 7.6996818

Consider the following four titrations (a-d):
a. 120 mL of 0.2 M C2H5NH2 (Kb = 5.6×10-4) by 0.2 M HNO3
b. 120 mL of 0.2 M KOH by 0.2 M HNO3
c. 120 mL of 0.2 M HC3H5O2 (Ka = 1.3×10-3) by 0.2 M KOH
d. 120 mL of 0.2 M HNO2 (Ka = 4.0×10-4) by 0.2 M KOH
Part 1
Rank the four titrations in order of increasing pH at the halfway point to equivalence (lowest to highest pH). Use the letters a, b, c, and d to represent the various titrations.
Part 2
Rank the four titrations in order of increasing pH at the equivalence point. Use the letters a, b, c, and d to represent the various titrations.
Part 3
Which titration requires the largest volume of titrant (HNO3 or KOH) to reach the equivalence point? (Enter "none" if no titration requires more than the others.)
Answers
Part 1:
The halfway point to equivalence corresponds to the point where half of the acid or base has reacted with the titrant. At this point, the moles of acid and base are equal and the solution is a buffer solution. The pH of a buffer solution depends on the pKa of the acid and the ratio of the concentrations of the acid and its conjugate base (or the base and its conjugate acid). Using the Henderson-Hasselbalch equation, we can estimate the pH at the halfway point for each titration:
a. C2H5NH2 + HNO3 → C2H5NH3+NO3-
pKa = 10.74
At the halfway point, [C2H5NH2] = [C2H5NH3+], so
pH = pKa + log([C2H5NH3+]/[C2H5NH2]) = 10.74 + log(1) = 10.74
b. KOH + HNO3 → KNO3 + H2O
At the halfway point, [HNO3] = [KNO3], so the solution is neutral and pH = 7.
c. HC3H5O2 + KOH → KC3H5O2 + H2O
pKa = 4.87
At the halfway point, [HC3H5O2] = [C3H5O2-], so
pH = pKa + log([C3H5O2-]/[HC3H5O2]) = 4.87 + log(1) = 4.87
d. HNO2 + KOH → KNO2 + H2O
pKa = 3.30
At the halfway point, [HNO2] = [NO2-], so
pH = pKa + log([NO2-]/[HNO2]) = 3.30 + log(1) = 3.30
Ranking from lowest to highest pH at halfway point: b, a, c, d (Note that titration b is a strong acid-strong base titration, which does not form a buffer and has a neutral pH at the halfway point.)
Part 2:
At the equivalence point, all of the acid or base has reacted with the titrant and the solution is either neutral or basic, depending on the acid-base strength of the components. For a strong acid-strong base titration, the equivalence point is pH 7. For a weak acid-strong base titration, the equivalence point is greater than pH 7, and for a strong acid-weak base titration, the equivalence point is less than pH 7. Using this information, we can rank the titrations at the equivalence point:
a. pH at equivalence point < 7 (weak base-strong acid titration)
b. pH at equivalence point = 7 (strong acid-strong base titration)
c. pH at equivalence point > 7 (weak acid-strong base titration)
d. pH at equivalence point < 7 (weak acid-strong base titration)
Ranking from lowest to highest pH at equivalence point: a, d, b, c
Part 3:
The volume of titrant required to reach the equivalence point depends on the number of moles of acid or base present in the sample. For a 0.2 M solution of acid or base, the number of moles present in 120 mL is:
moles = concentration x volume = 0.2 x 0.12 = 0.024
Using this information, we can calculate the number of moles
