The following diagram on the left represents the copper nitrate solution in the half‑cell before the galvanic cell starts to ope

rate. In the following diagram on the right, draw a representation of the solution in the same half‑cell after the galvanic cell has been operating for some time and is still producing a voltage.

Answer:

There is too much here for me to attempt in one sitting, but I will get you started and give suggestions that may help you proceed on your own.

a)  As far as I can tell, you didn't provide the reduction potentials in the table below.  So, I looked them up and find them to be

Cu2+ +2e- ==> Cu(s)  Eº = +0.34 V

Zn2+ + 2e- ==> Zn(s)  Eº = -0.76 V

Net ionic equation:  Cu2+(aq) + Zn(s) ==> Cu(s) + Zn2+(aq)

b)  Eºcell = 0.34 V + 0.76 V = 1.10 V

c)  ∆Gº = -nFEº  where n = number of electrons transferred (2) and F = 96,485 C/mol e- and Eº = 1.1 V

d)  Again, there is no diagram

e)  same

f)  Use the Nernst equation  Ecell = Eºcell - 2.303RT/nF log Q  where R = 8.314; T = Kelvin; F = Faraday const. and Q = reaction quotient, i.e. products/reactants

g)  the cell voltage is an intensive property.  That should help you answer this part of the question

Explanation:

its not much but i hoped this helped

How do purple stem plants use there energy
tatuchka [14]
Purple stem plants can be formed by genetics, they use their energy slightly different from other plants, they use less energy, but that may also be because of bad nutrition, and because they may be hungry for nutrients.

Which substance has the highest melting point?
Andre45 [30]
<span>A.H2O = water, so it is a liquid at room temperatures (melting point = 0C) and melting point must be below 20C

B.HCl = A gas at room temperatures, so melting point (-114C) is definitely lower than 20C.
Melting points of the aqueous solution (solution in water) at different concentrations are all below that of water, i.e. 0C.

C.CH4 = A gas at room temperatures, so melting point (-182C) must be below 20C.

D.MgCl2 = A white powdery solid at room temperatures, so its melting point (714C) must be above 20C (So this is the only one among the four choices that melts above 20 &deg; C).</span>

A 20.0 L container at 303 K holds a mixture of two gases with a total pressure of 5.00 atm. If there are 1.70 mol of Gas A in th
meriva

Answer:

moles B = 2.32 moles

Explanation:

In this case, we can assume that both gases are ideals, so we can use the expression for an ideal gas which is:

PV = nRT

From here, we can calculate the total moles (n) that are in the container, and then, by difference, we can calculate how much we have of gas B.

For this case, we will use R = 0.082 L atm / mol K. Solving for n:

n = PV/RT

n = 5 * 20 / 0.082 * 303

n = 4.02 moles

If we have 4.02 moles between the two gases, and we have 1.70 from gas A, then from gas B we simply have:

Total moles = moles A + moles B

moles B = Total moles - moles A

moles B = 4.02 - 1.70

moles B = 2.32 moles

We have 2.32 moles of gas B
