use the tabulated half-cell potentials to calculate k for the oxidation of nickel by chlorine: cl2(g) ni(s) 2 cl-(aq) ni2 (aq)

Answers

Answer 1

The calculation of K requires the actual cell potential (Ecell), which depends on the specific conditions (such as concentrations) of the reaction.

To calculate the standard cell potential (E°) for the oxidation of nickel (Ni) by chlorine (Cl2), we need to use the tabulated half-cell potentials and apply the Nernst equation.

The half-reactions involved in the oxidation of nickel and reduction of chlorine are as follows:

Oxidation (anode): Ni(s) → Ni^2+(aq) + 2e^-

Reduction (cathode): Cl2(g) + 2e^- → 2Cl^-(aq)

The standard reduction potentials (E°) for these half-reactions are typically provided in tables. Let's assume the values are:

E°(Ni^2+/Ni) = -0.25 V

E°(Cl2/2Cl^-) = 1.36 V

To calculate the standard cell potential (E°cell), we subtract the reduction potential of the anode from the reduction potential of the cathode:

E°cell = E°(cathode) - E°(anode)

E°cell = 1.36 V - (-0.25 V)

E°cell = 1.61 V

The Nernst equation relates the standard cell potential (E°cell) to the actual cell potential (Ecell) under non-standard conditions:

Ecell = E°cell - (0.0592 V/n)log(Q)

Where:

Ecell is the actual cell potential

Q is the reaction quotient (products/reactants ratio)

n is the number of electrons transferred in the balanced equation

In this case, the reaction quotient (Q) is determined by the concentrations of the species involved. However, since no concentrations are provided in the given equation, we assume standard conditions where the concentrations of all species are 1 M.

Using the Nernst equation, we can write:

Ecell = E°cell - (0.0592 V/2)log([Cl^-]^2/[Ni^2+])

Since we are interested in calculating the equilibrium constant (K) for the reaction, we can rearrange the equation as follows:

Ecell = E°cell - (0.0592 V/2)log(K)

By rearranging further, we can isolate K:

K = 10^((E°cell - Ecell) / (0.0592 V/2))

Substituting the given values:

E°cell = 1.61 V

Ecell = unknown (since it depends on the actual conditions)

K = unknown (what we're trying to calculate)

Keep in mind that the calculation of K requires the actual cell potential (Ecell), which depends on the specific conditions (such as concentrations) of the reaction. Without these specific conditions, we cannot determine the value of K.

A molecule with the formula ab3 and a trigonal planar molecular geometry uses ________ to form its σ bonds.

Answers

A molecule with the formula ab3 and a trigonal planar molecular geometry uses sp2 hybridization to form its σ bonds.

Trigonal hybridization is another name for sp2 hybridization. To create the new hybrid orbital known as sp2, one's orbital and two 'p' orbitals of equal energy are mixed together. Trigonal symmetry was used to generate a mixture of s and p orbitals, which are kept at 1200.

One s orbital and two p orbitals combine to generate three sp2 hybridizations, each of which has a 33 percent s character and a 67 percent p character. This process is known as sp2 hybridization. Anytime an atom is surrounded by three groups of electrons, this kind of sp2 hybridization is necessary.

Both the carbon and oxygen atoms are sp2 hybridized. The carbon atom can establish three bonds, one of which is to the oxygen, and possesses three sp2 hybridized orbitals.

Ammonia, NH3, undergoes reaction with oxygen to form nitrogen and water. When 7.00 x 1022 molecules of ammonia react with 6.00 x 1022 molecules of oxygen, what mass of nitrogen results (grams)

Answers

Amount of nitrogen produced = 1.624 g

To calculate the moles, we use the equation:    

4NH3(g) + 3 O2 (g) ---> 2 N2 (g) + 6 H2O (g)                           ....(1)

For ammonia:

Putting values in above equation, we get:

Moles of ammonia = 7.00 x 1022 / 6.023 * 10 ^23 = 0.116 mol

Moles of oxygen = 6.00 x 1022 / 6.023 * 10 ^23 = 0.099 mol

For the reaction:

4NH3(g) + 3 O2 (g) ---> 2 N2 (g) + 6 H2O (g)

By Stoichiometry of the reaction,

4 moles of ammonia combine with 3 moles of Oxygen

Thus 0.116 moles of ammonia will combine with= 3/4 * 0.116 = 0.087 of oxygen

Thus ammonia is the limiting reagent as it limits the formation of product.

4 moles of ammonia produces 2 moles of nitrogen

0.132 moles of ammonia will produce=2/4 * 0.116 = 0.058 of nitrogen

Molar mass of nitrogen =  28 g/mol

If you have 100 ml of a 0.10 m tris buffer (pka 8.3) at ph 8.3 and you add 3.0 ml of 1.0 m hcl, what will be the new ph?

The Henderson Hasselbalch equation is an approximate equation that shows the relationship between the pH or pOH of a solution and the pKa or pKb and the ratio of the concentrations of the dissociated chemical species. To calculate the pH of the buffer solution made by mixing salt and weak acid/base. It is used to calculate the pKa value. Prepare buffer solution of needed pH.

For high-cis polymers compared to their cis/trans counterparts, the rate of breakdown in the tetrahydrofuran solution increased by up to three orders of magnitude. In an aerated tetrahydrofuran solution, there was considerable cis-to-trans isomerization along with the degradation of high-cis PFPhAs.The F-position on the Ph ring showed the similar dependence on the rate of degradation and isomerization. It was proposed that cis-to-trans isomerization, which increases the amount of unpaired electrons on the main chains, hastened the degradation of high-cis PFPhAs in solution. The ortho-substituted isomers shown increased stability compared to the meta- and para-substituted isomers in both the high-cis and cis/trans series of polymers.
