An electrochemical cell is composed of pure copper and pure cadmium electrodes immersed in solutions of their respective divalent ions. For a 6.5 × 10-2 M concentration of Cd2+, the cadmium electrode is oxidized, yielding a cell potential of 0.775 V. Calculate the concentration of Cu2+ ions if the temperature is 25°C.
From the calcuation, the concentration of the copper II ion is 0.98 M.
What is an electrochemical cell?An electrochemical cell is one in which current is produced by means of a chemical reaction. In this cell, the cell reaction is;
Cd(s) + Cu^2+(aq) ----> Cd^2+(aq) + Cu(s)
E°cell = 0.34 V - (-0.40V) = 0.74 V
Using the Nernst equation;
0.775= 0.74 - 0.0592/2 log(6.5 × 10-2)/[Cu^2+]
0.775 - 0.74 = - 0.0592/2 log(6.5 × 10-2)/[Cu^2+]
0.035 = -0.0296 log(6.5 × 10-2)/[Cu^2+]
0.035 /-0.0296 = log(6.5 × 10-2)/[Cu^2+]
-1.18 = log(6.5 × 10-2)/[Cu^2+]
Antilog (-1.18) = (6.5 × 10-2)/[Cu^2+]
0.066= (6.5 × 10-2)/[Cu^2+]
[Cu^2+] = (6.5 × 10-2)/0.066
[Cu^2+] =0.98 M

If you can't ignore a distraction, as a driver you should: D. Both A and B.
What is a distraction?A distraction can be defined as any form of event that is capable of making a driver to loose concentration or lure his or her eyes away from the road.
This ultimately implies that, a distraction can cause a driver to experience a road accident (car crash) if not properly managed or ignored.
In conclusion, if you can't ignore a distraction, as a driver you should pull over or take care of it at your next planned stop.

A closed thermodynamic cycle consists of two isobaric and two isochoric processes. The processes operate between 0.43 MPa and 4.3 MPa and 0.28 m3 and 2.9 m3. Determine the total work (with appropriate sign) for one complete cycle, when the cycle operates in the clockwise direction. Provide your result in MJ.
Answer:
Explanation:
For first isobaric process (expansion with constant pressure):
[tex]W_{1}=P_{1}(V_{2}-V_{1})=(0.43\times 10^{6})(2.9-0.28)=1.1266 \times 10^{6} J=1.1266 MJ(+) (Expansion)[/tex]
Now, for the first isochoric: [tex]W_{2}=0[/tex], and [tex]Q_{2}=\Delta U=U_{3}-U_{2}[/tex]
For the second isobaric process (compression with constant pressure):
[tex]W_{3}=P_{2}(V_{1}-V_{2})=(4.3\times 10^{6})(0.28-2.9) =-11.266\times 10^{6}J=-11.266 MJ (Compression)[/tex]
For the last isochoric: [tex]W_{4}=0, Q_{4}=\Delta U=U_{4}-U_{3}[/tex]
So, the total work per cycle: [tex]W=W_{1}+W_{2}+W_{3}+W_{4}=1.1266+0-11.266+0=-10.1394 MJ[/tex]
A gaseous mixture contain 32.9 mol % He, 40.7 mol % N_{2} and 26.4 mol % Ar. Determine the composition of this mixture on a mass basis based on the molecular weight given: MW(He) = 4.003 , MW (N_{2}) = 28.02 MW(Ar) = 39.95
The composition of the mixture on a mass basis are as follows:
He = 131.70 gN2 = 1140.41 gAr = 1054.68 gnumber of moles = mass of substnce / molar mass
molar mass and molecular weight has equal numerical values therefore
Number of moles = mass of substnce / molecular weight
mass of substance = number of moles * molecular weight
the moles are expressed in percentage hence the total moles should be 100
check: 32.9 + 40.7 + 26.4 = 100
He
mass of substance = 32.9 * 4.003 = 131.6987 g
[tex]N_{2}[/tex]
mass of substance = 40.7 * 28.02 = 1140.414 g
Ar
mass of substance = 26.4 * 39.95 = 1054.68 g

A farmer has 12 hectares of land on which he grows corn, wheat, and soybeans. It costs $4500 per hectare to grow corn, $6000 to grow wheat, and $5000 to grow soybeans. Because of market demand the farmer will grow twice as many hectares of wheat as corn. He has allocated $6,375,000.00 for the cost of growing his crops. How many hectares of each crop should he plant?
The number of hectares of each crop he should plant are; 250 hectares of Corn, 500 hectares of Wheat and 450 hectares of soybeans
How to solve algebra word problem?
He grows corn, wheat and soya beans on the farm of 1200 hectares. Thus;
C + W + S = 12 ----(1)
It costs $45 per hectare to grow corn, $60 to grow wheat, and $50 to grow soybeans. Thus;
45C + 60W + 50S = 63750 -----(2)
He will grow twice as many hectares of wheat as corn. Thus;
W = 2C ------(3)
Put 2C for W in eq 1 and eq 2 to get;
C + 2C + S = 1200
3C + S = 1200 -----(4)
45C + 60(2C) + 50S = 63750
45C + 120C + 50S = 63750
165C + 50S = 63750 ------(5)
Solving eq 4 and 5 simultaneosly gives;
C = 250 and W = 500
Thus; S = 1200 - 3(250)
S = 450

Explanation:
The "allowance" is the difference between the maximum shaft size and the minimum hole size.
maximum shaft = C +D = 8.5 +0.1 = 8.6
minimum hole = A -B = 4.8 -0.4 = 4.4
Allowance = 8.6 -4.4 = 4.2

For an interference fit, the allowance is negative.
A capacitor is connected across an ac source. suppose the frequency of the source is doubled. what happens to the capacitive reactance of the capacitor?.
Answer:
Explanation:
The capacitive reactance of the capacitor is determined by [tex]X_{C}=\frac{1}{\omega C}[/tex]
When [tex]f'=2f \rightarrow \omega' =2\omega[/tex]
