The concentration of Iron in the galvanic (voltaic) cell Fe(s) + Mn²⁺(aq) ⟶ Fe²⁺(aq) + Mn(s) is 0.02297 M.
What is the Nernst Equation?The Nernst equation enables us to identify the cell potential(voltage) in presence of non-standard conditions in a galvanic cell. It can be expressed by using the formula:
[tex]\mathbf{E_{cell} = E_o - \dfrac{0.059}{n} \times log \dfrac{[Fe^+]}{[Mn^{2+}]}}[/tex]
where;
n = Number of electrons = 2[tex]\mathbf{E_o}[/tex] = Initial voltage = 0.77 V[tex]\mathbf{E_{cell}}[/tex] = Cell voltage = 0.78 V[tex]\mathbf{[Mn^{2+}]}[/tex] = Manganese concentration = 0.050 MReplacing the values into the above equation, we have:
[tex]\mathbf{0.78 = 0.77 - \dfrac{0.059}{2} \times log \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]
[tex]\mathbf{0.78 -0.77= -0.0296\times log \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]
[tex]\mathbf{log^{-1} (-0.3378) = \dfrac{[Fe^{2+}]}{[0.050]}}[/tex]
[tex]\mathbf{Fe^{2+} = (0.4594\times 0.050 )\ M}[/tex]
[tex]\mathbf{Fe^{2+} =0.02297 \ M }[/tex]

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted.

Which function is continuous at x = 18? f (x) = startfraction (x minus 18) squared over x endfraction f (x) = startfraction x squared minus 17 x minus 18 over x minus 18 endfraction f (x) = tangent (startfraction pi over 36 endfraction x) f (x) = startlayout enlarged left-brace first row x squared, x not-equals 18 second row 36, x = 18 endlayout
The function that is continuous at x = 18 is:
y = (x - 18)/x
Which function is continuous at x = 18?
We need to see which function has no problems when x = 18.
For example, the first one:
y = (x - 18)/x
When x = 18, we have:
y = (18 - 18)/18 = 0
Then this function is continuous at x = 18.
When, for the second option, we have (x - 18) on the denominator, and then when x = 18 the denominator becomes 0, so that function is not continuous at x = 18.
With that, we conclude that the correct option is the first one.

Building sheep pens : darsh and darpan are fencing off a large rectangular area to build some temporary holding pens. to prep the males, females, and kids, they are separated into three smaller and equal-size pens partitioned within the large rectangle. (i) if 384 ft of fencing is available and the maximum area is desired, what will be the dimensions of the larger, outer rectangle? (ii) what will be the dimensions of the smaller holding pens?
The dimensions of the larger outer rectangle and smaller holding pens are respectively; 96ft x 96ft and 31ft x 96ft
How to maximize Functions?Let the side lengths of the big rectangle be x and y. Thus the area of the big triangle is; A = xy
If the fencing available is 384 ft, then perimeter is 384 ft. Thus;
2x + 2y = 384
y = (384 - 2x)/2
y = 192 - x
Putting 192 - x for y in A gives us;
A = x(192 - x) = 192x - x²
Completing the square to rearrange the equation of A gives us;
A = 9216 - (x - 96)²
If A is to be a maximum, then;
x - 96 = 0
x = 96 ft
y = 192 - 96 = 96 ft
Since we maximised the area of the bigger rectangle , we have maximised the area of the smaller pens. The dimensions of the smaller holding pens will be;
x' = 96 ft /3 = 31 ft
y' = 96 ft
