Which of the following correctly compares the radii of F and F−?

A) F has a smaller radius than F− because an additional electron causes greater repulsion in F−.
B) F has a larger radius than F− because an additional electron causes greater repulsion in F.
C) F has a smaller radius than F− because F− has an additional energy shell.
D) F has a larger radius than F− because F has an additional energy shell.

Answers

The answer is C.
Hope this helps:)

F has a smaller radius than F− because F− has an additional energy shell  correctly compares the radii of F and F−. The correct option is C.

Thus, Compared to oxygen, fluorine is a stronger electronegative element. The outermost electrons of fluorine are gripped by the nucleus more tightly than oxygen because fluorine has a high electronegativity.

It takes more energy to remove the outermost electron of fluorine than it does to remove the outermost electron of oxygen. Fluorine has a higher ionization energy than oxygen as a result.

An atom's energy is determined by how much energy it gains or loses as a result of chemical processes that result in electron loss or gain. Exothermic reactions are those in which energy is released, and endothermic reactions are those in which energy is absorbed.

Exothermic reactions produce negative energy, which is why energy is given a negative sign.

Thus,  F has a smaller radius than F− because F− has an additional energy shell   correctly compares the radii of F and F−. The correct option is C.

Solid nickel reacts with aqueous lead (II) nitrate to form solid lead. What is the net ionic equation for this reaction? • Hint: In this reaction, nickel exhibits its most common oxidation state of +2. • Be sure to include the charge for each ion in the net ionic equation. Provide your answer below: (s) + (aq) → *(n)

Answers

Answer:

Pb²⁺(aq) --> Ni²⁺(aq)

Explanation:

The equation of the reaction is given as;

Ni(s) + Pb(NO₃)₂(aq) --> Pb(s) + Ni(NO₃)₂(aq)

In writing the ionic equation, we break the aqueous compound into ions. The solid and liquid compounds are ignored.

We have;

Pb²⁺(aq)  + NO₃²⁻(aq) -->  Ni²⁺(aq)  + NO₃²⁻(aq)

Canceling the spectator ions;

Pb²⁺(aq) --> Ni²⁺(aq)

Answer:

Ni(s)+Pb2+(aq)→Ni2+(aq)+Pb(s)

Explanation:

The complete ionic equation of this reaction is

Ni(s)+Pb2+(aq)+2 NO−3(aq)→Ni2+(aq)+2 NO−3(aq)+Pb(s)

The nitrate ions are spectator ions and can be removed from the equation, giving us

Ni(s)+Pb2+(aq)→Ni2+(aq)+Pb(s)

The greatest absorbance occurs when the solution and beam color are the ______ because the solution color appearance is the color being ___________ by the solution.

Answers

Answer:

Same

Absorbed

Explanation:

When you are dealing with solutions the best way to tell that something has been absorbed is when the solution and the beam color are the same, since they have the same color you can be sure that the color has been absorbed properly and the greatest absorbance has occured.

The fill in the blanks should be filled with the same and absorbed.

The following information should be considered:

At the time when you deal with the solutions, the best way is that something should be absorbed at the time when the solution & beam color should be similar. As it contains the similar color so the color should been absorbed properly & the highest absorbance should be arise.

Therefore we can conclude that the fill in the blanks should be filled with the same and absorbed.

Predict and write the charges and symbols of the monatomic ions formed by the following atoms: bromine rubidium

Answers

Answer: The monoatomic ions formed by bromine and rubidium are [tex]Br^-[/tex] and [tex]Rb^+[/tex] respectively.

Explanation:

When an atom accepts an electron negative charge is created on atom and is called as anion.  When atom loses an electron positive charge is created on atom and is called as cation.

The atomic number of bromine and rubidium is 35 and 37 respectively. So, the number of electrons is equal to 35 and 37 respectively. Bromine will gain one electron and rubidium will lose one electron to attain stable electronic configuration to form [tex]Br^-[/tex] and [tex]Rb^+[/tex] respectively.

Explanation:

According to the second law of thermodynamics, the energy of the universe is conserved but the entropy of the universe is continuously increasing.

What is the second law of thermodynamics?

The second law of thermodynamics put some restrictions on the direction of heat transfer and attainable efficiencies of heat engines. This law stated that any spontaneously happening process will lead to an escalation in the entropy (S) of the universe.

This law explains that the entropy of an isolated system will never decrease with time. Mathematically, the 2nd law of thermodynamics:

ΔS (universe) > 0

where ΔS of the universe is the change in the entropy of the universe.

The second law of thermodynamics provides the criterion for the feasibility of any physical or chemical process. A physical or chemical process cannot take place unless it must follow both the 1st and 2nd laws of thermodynamics.

Select the compound that is most likely to increase the solubility of AgCl when added to water.

a. MgBr2
b. KClO4
c. NH3
d. NaCl

Answers

Answer:

c

Explanation:

The compound which increase the solubility of AgCl in water is determined on the basis of the process called common ion effect. The solubility of AgCl will be maximum in NH₃. The correct option is C.

What is common ion effect?

The process common ion effect can be defined as the suppression of the dissociation of a weak electrolyte (weak acid or weak base) by the addition of some strong electrolyte containing common ion.

The solubility is defined as the maximum amount of solute that can be dissolved in a given solvent. Here AgCl dissociates into Ag⁺ and Cl⁻ ions. Both KClO₄ and NaCl contain Cl⁻ ions and thus common ion effect takes place. So the solubility decreases.

When AgCl is dissolved in NH₃ it forms a complex [ Ag (NH₃)₂]⁺. So it is highly soluble in NH₃. It is also soluble in water but not more than NH₃.

Thus the correct option C.

Explanation:

Peptides can be separated using an ion‑exchange column based on their isoelectric (pI) values. At which pH values would two different peptides, one with a pI of 5.3 and the other with a pI of 8.5 , bind to a cation‑ and anion‑exchange column? Each peptide may be capable of binding to each column at more than one pH value.

Answers

Answer:

At pH 3.5:

Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the anion-exchange column.

At pH 6.5:

Peptide A with pI 5.1 will bind to the cation-exchange column, while peptide B with pI 8.5 will bind to the anion-exchange column.

At pH 10.8:

Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the cation-exchange column.

Explanation:

Ion-exchange column chromatography is used for separating proteins and other molecules in a solution based on differences in net  charge. Negatively charged molecules bind to positively charged solid supports called the anion-exchange column, whereas, positively charged molecules bind to  negatively charged solid supports known as cation-exchange column.

A peptide can acquire a net charge if the pH of the medium is either above or below its isoelectric point,pI. At pH above pI, the peptide acquires a net negative charge and can bind to a positive support. At pH above pI, the peptide acquires a net positive charge and can bind to a negative support. The greater the difference between pH and pI, the tighter the peptide will bind to the column.

At pH 3.5:

Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the anion-exchange column.

At pH 6.5:

Peptide A with pI 5.1 will bind to the cation-exchange column, while peptide B with pI 8.5 will bind to the anion-exchange column.

At pH 10.8:

Peptide A with pI 5.1 and peptide B with pI 8.5 will both bind to the cation-exchange column.

roducts
OC. The concentrations of reactants and products are not constant.
D. The concentration of the products is higher than that of the reactants.

Answers

Answer:

B. The products can form reactants, and the reactants can form products.

Explanation:

Depending on whether products of a chemical reaction can form their reactants or not, a chemical reaction can be irreversible or reversible.

Irreversible chemical reactions occur in only one direction. The reactants can form products, but the products cannot change back to the reactants.

Reversible chemical reactions occur in both directions, which means that the products can change back to the reactants under certain conditions, as well. This is something that always applies to reversible chemical reactions, which is why option B is the correct one.

The products can form reactants, and the reactants can form products
