A voltaic cell consists of a Pb/Pb2 and a Cu/Cu2 half cells at 25 degrees Celsius. The initial concentrations of Pb2 and Cu2 are 0.05M and 1.5M respectively. What are the concentrations of Pb2 and Cu2 when the cell potential falls to 0.35V
Answers
The concentrations of Pb₂+ and Cu₂+ when the cell potential falls to 0.35 V are 0.0147 M and 1.5 M, respectively.
To solve this problem, we can use the Nernst equation, which relates the standard cell potential to the concentrations of the species involved in the cell reaction. The Nernst equation is given by:
E = E° - (RT/nF) * ln(Q)
where:
E is the cell potential
E° is the standard cell potential
R is the gas constant (8.314 J/mol·K)
T is the temperature in kelvin
n is the number of electrons transferred in the cell reaction
F is Faraday's constant (96,485 C/mol)
For the given voltaic cell, the half-cell reactions and their standard reduction potentials are:
Pb₂+ + 2e- → Pb(s) E° = -0.13 V
Cu₂+ + 2e- → Cu(s) E° = +0.34 V
The overall cell reaction is:
Pb(s) + Cu₂+ → Pb₂+ + Cu(s)
The cell potential can be calculated as:
E = E° - (RT/nF) * ln(Q)
We are given that the initial concentrations of Pb₂+ and Cu₂+ are 0.05 M and 1.5 M, respectively. Therefore, the reaction quotient is:
Q = [Pb₂+]/[Cu₂+] = 0.05/1.5 = 0.0333
At this point, we do not know the cell potential, but we are told that it falls to 0.35 V. We can use this information to solve for the final concentrations of Pb2+ and Cu2+. Rearranging the Nernst equation, we get:
ln(Q) = (E° - E) * (nF/RT)
Substituting the given values, we get:
ln(0.0333) = (-0.13 - 0.34 - 0.035) * (2 * 96,485 / (8.314 * 298))
Solving for E, we get:
E = 0.035 V
Substituting this value back into the Nernst equation, we can solve for the final concentrations of Pb2+ and Cu2+:
E = E° - (RT/nF) * ln(Q)
0.035 = -0.13 - 0.34 - (2 * 96,485 / (8.314 * 298)) * ln([Pb₂+]/[Cu₂+])
Solving for [Pb₂+]/[Cu₂+], we get:
[Pb₂+]/[Cu₂+] = exp(-(0.035 + 0.13 + 0.34) * (8.314 * 298) / (2 * 96,485)) = 0.0098
Multiplying both sides by [Cu₂+], we get:
[Pb₂+] = 0.0098 * [Cu₂+] = 0.0098 * 1.5 = 0.0147 M
Therefore, the concentrations of Pb2+ and Cu2+ when the cell potential falls to 0.35 V are 0.0147 M and 1.5 M, respectively.

A non-polar stationary phase is used in normal-phase HPLC C. Compounds have a lower attraction to the mobile phase than to the stationary phase in displacement development D. A polar stationary phase is used in reversed-phase HPLC E. More polar compounds elute first in normal-phase HPLC
Answers
The following statements on HPLC modes are true is more polar compounds elute first in normal-phase HPLC (Option E).
The liquid chromatography (HPLC) is a technique in analytical chemistry employed for the separation, identification, and quantification of elements. It is considered a highly sensitive method, and it works by separating the components in a mixture with the assistance of a solvent under high pressure.
There are two modes of HPLC: Reversed-Phase HPLC (RP-HPLC) and Normal-Phase HPLC (NP-HPLC). In RP-HPLC, a nonpolar stationary phase, such as C18, is used, and polar solvents, such as water, are used as mobile phases. Polar stationary phases, such as silica gel, are used in NP-HPLC, while nonpolar solvents, such as hexane, are used as mobile phases.
More polar compounds have a greater affinity for the polar stationary phase than less polar compounds, which have a higher affinity for the nonpolar mobile phase in NP-HPLC. As a result, less polar compounds elute first in normal-phase HPLC.
Thus, the correct option is E.

Answers
Answer
We have the following chemical reaction:
\(Zn+2HCl\rightarrow ZnCl_2+H_2\)We can see that the equation is balanced because we have the same number of each atom in both sides of the equation.
Now, as we can see in the equation, for every mol of Zn that reacts it is needed 2 moles of HCl. Therefore we can calculate the moles of HCl needed in total as follows:
\(n_{HCl}=2.9mol.\frac{2molHCl}{1molZn}=5.8mol\)So the answer is: there are needed 5.8 mol.

The percent ionization of a 0.331M solution of HCN is found to be 0.00337%. What is the pH of this solution?
a. 1.992 b. 2.953 c. 3.371 d. 3.992 e. 4.953
Answers
The percent ionization of a 0.331M solution of HCN is found to be 0.00337%. The pH of the solution is 4.953. The correct option is E. 4.953.
To solve this problem, we need to use the equation for percent ionization:
% ionization = (concentration of ionized acid / initial concentration of acid) x 100%
We can rearrange this equation to solve for the concentration of ionized acid:
concentration of ionized acid = % ionization / 100% x initial concentration of acid
Plugging in the given values, we get:
concentration of ionized acid = 0.00337 / 100 x 0.331 = 0.000011187 M
Now, we can use the equation for the ionization of HCN to set up an expression for the equilibrium constant (Ka):
HCN + H2O ↔ H3O+ + CN-
Ka = [H3O+][CN-] / [HCN]
We can assume that the concentration of H3O+ is equal to the concentration of ionized acid, since the ionization of HCN produces one H3O+ ion for every HCN molecule that ionizes. We can also assume that the concentration of CN- is equal to the concentration of H3O+.
Therefore:
Ka = (concentration of ionized acid)^2 / (initial concentration of acid - concentration of ionized acid)
Plugging in the values we calculated, we get:
Ka = (0.000011187)^2 / (0.331 - 0.000011187) = 6.2 x 10^-10
Now, we can use the equation for the pH of a weak acid:
pH = pKa + log([A-] / [HA])
Since we assumed that the concentration of CN- is equal to the concentration of ionized acid, we can substitute [CN-] for [A-] and [HCN] - [CN-] for [HA]. We also know that pKa = -log(Ka).
Therefore:
pH = -log(6.2 x 10^-10) + log(0.000011187 / (0.331 - 0.000011187)) = 4.953
Therefore, the pH of the solution is e. 4.953.

As a result the student collects 28.0 g of hydrogen and 224.0 g of oxygen. How many grams of water did the student originally start with?
Answers
The amount, in grams, of water, that the student originally started with would be 252 g
From the balanced equation of the reaction, the ratio of H2O to H2 is 1:1. Thus for every 1 mole of water that is separated, 1 mole of H2 is produced.
Recall that: mole = mass/molar mass
Mole of 28.0 g H2 produced = 28/2
= 14 moles
Equivalent mole of H2O would, therefore, be 14 moles.
Mass of 14 moles H2O = mole x molar mass

Option D. Uniformitarianism is the principle stating that the physical, chemical, and biological processes at work shaping the Earth today have also operated in the geologic past. It is based on the idea that the present is the key to the past. In other words, the same natural laws that operate in the universe today have been operating since the beginning of time.
James Hutton was the first to propose this principle in the late 18th century. He suggested that the Earth was shaped by slow-acting geological forces such as erosion, sedimentation, and uplift over long periods of time. He believed that the same processes were still happening today and that they had operated in the past.
This principle is an important concept in geology because it allows scientists to interpret the Earth's history based on the processes that they observe today. By understanding how these processes work and how they have changed over time, scientists can reconstruct the history of the Earth and its environments.
Uniformitarianism has been tested and proven through many observations and experiments. For example, the study of sedimentary rocks has shown that they were formed in the past through the same processes that are observed today, such as deposition of sediment by water, wind, or ice.
Similarly, the study of volcanoes has shown that they are formed by the same processes as today, such as the movement of magma from deep within the Earth.
In conclusion, Uniformitarianism is the principle that allows us to interpret the Earth's history by observing the processes that shape it today. It is a fundamental concept in geology and has been tested and proven through many observations and experiments.

Potential energy is energy that is stored in an object. It isn't being used at the moment, but is waiting to do work. A good example is to think about a boulder sitting on top of a hill. Just sitting there, the boulder isn't doing anything. But because it is sitting on top of a hill, it has the potential to roll down and do some damage to a car or building below. The energy is stored in that rock because of its size (mass) and the distance it will travel once it starts rolling. Another good example is a rubberband. When you stretch a rubber band, it wants to move back to its original position, and thus you have given it potential energy. As the rubber band is released, potential energy is changed to motion.
Kinetic energy is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy. This energy is performing work. Other examples of kinetic energy include: legs pump bicycle pedals, lightning snaps trees, cars travel down the street, football players making tackles, and 4-wheelers speeding through the woods.
Potential energy is converted into kinetic energy. As mentioned before, a stretched rubberband can change from having potential to kinetic energy. Another example of this change between kinetic and potential energy can be seen using a yo-yo. Before a yo-yo begins to fall from your hand it has stored energy due to its position. At the top (in your hand) it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been completely converted into kinetic energy so that it now has its maximum kinetic energy. Another example of the change between kinetic and potential energy is a waterfall. A waterfall has both potential and kinetic energy. The water at the top of a waterfall has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy is used in Niagara Falls, Canada to provide electricity to parts of the northeastern United States.
