Answer:

Ketone

Explanation:

According to the description of the functional group attached to the hydrocarbon - the first and last of a chain of three carbons are each single bonded to 3 hydrogen (H)atoms; the center carbon is double bonded to an oxygen atom, O - it can be deduced that the functional group is a ketone group.

A ketone is a functional group with the structure R₂-C=O, where the two R are  alkyl or phenyl groups which may be the same or different. The carbon in a double covalent bond with oxygen is called the carbonyl carbon. The two R groups are bonded to the carbonyl carbon in single covalent bonds.

In the hydrocarbon in this question, the two R groups are methyl groups, CH₃ bonded to the carbonyl carbon. The name of the hydrocarbon is propanone and it is a ketone molecule.

In giant covalent structures such as graphite or diamond, the atoms form strong bonds by sharing electrons. Therefore, the given statement is true.

A covalent bond can be defined as a chemical connection formed by the sharing of electron sets between particles. A covalent bond can be created by the mutual sharing of electrons from both atoms.

The pair of electrons that are shared in this kind of bonding is known as the shared or bonding pair. Covalent bonds are the sharing of bonding pairs of electrons that will provide the stability of the atom in its outer shell.

Elements that have very high ionization energies are incapable of exchanging electrons or elements having low electron affinity cannot accept electrons. Covalent bonding between two non-metallic atoms is characterized by the equal sharing of electrons between the atoms and covalent bonds with an electronegativity difference of participating atoms is more than 2.0.

Therefore, a giant structure like a diamond has strong covalent bonds that require a lot of energy to break.

Carbon buildup can be effectively removed from the metal portion of a pressing comb by immersing it in a solution containing an acidic compound. The acidic solution helps to dissolve and loosen the carbon deposits, making it easier to remove them from the comb.

One common household item that can be used as an acidic solution is white vinegar (acetic acid). Vinegar is a mild acid that can effectively break down carbon deposits on metal surfaces. To use vinegar for cleaning the pressing comb, you can fill a container with enough vinegar to fully submerge the metal portion of the comb.

Leave the comb in the vinegar for a few hours or overnight to allow the acid to work on the carbon buildup. Afterward, you can scrub the comb with a soft brush or cloth to remove the loosened carbon deposits.

It's important to note that when using an acidic solution for cleaning, it's essential to rinse the comb thoroughly with water afterward to remove any residual acid and prevent damage to the comb or future interactions with hair.

To calculate the Ksp (solubility product constant) from the solubility of a compound, you need to follow these steps:

1. Write the balanced equation for the dissolution of the compound in water.
2. Identify the stoichiometry of the dissolved compound and the ions produced in the solution.
3. Write the expression for the Ksp using the stoichiometry of the ions and their concentration in the solution.
4. Use the solubility of the compound in water to calculate the concentration of the ions in the solution.
5. Substitute the ion concentrations into the Ksp expression and solve for the Ksp value.

For example, let's consider the dissolution of silver chloride (AgCl) in water:
AgCl(s) ⇌ Ag+(aq) + Cl-(aq)
The stoichiometry of the reaction tells us that one mole of AgCl produces one mole of Ag+ and one mole of Cl-. The Ksp expression for this reaction is:

Ksp = [Ag+][Cl-]
If we know that the solubility of AgCl in water is 1.2 x 10^-5 M, we can use this value to calculate the concentration of Ag+ and Cl- in the solution:
[Ag+] = [Cl-] = 1.2 x 10^-5 M
Substituting these values into the Ksp expression, we get:
Ksp = (1.2 x 10^-5)^2 = 1.44 x 10^-10

Therefore, the Ksp value for AgCl in water is 1.44 x 10^-10.

To calculate Ksp (solubility product constant) from solubility, follow these steps:
1. Write the balanced dissolution reaction: For the compound AB, the reaction would be AB(s) ↔ A⁺(aq) + B⁻(aq).
2. Determine the solubility: The solubility represents the concentration of the dissolved ions in a saturated solution, typically expressed in mol/L (molarity).
3. Set up the expression for Ksp: Ksp = [A⁺][B⁻], where [A⁺] and [B⁻] are the molar concentrations of the ions A⁺ and B⁻ in the saturated solution.
4. Calculate the Ksp: Plug in the solubility values you found in step 2 into the Ksp expression and solve for Ksp.
Remember that these steps are a general guideline and the actual calculation may differ depending on the specific compound and reaction being considered.

The equilibrium concentration of NOF is 0.067 M.

To determine the equilibrium concentration of NOF, we need to use the equilibrium constant (Kc) and the initial concentrations of the reactants. The equilibrium constant expression for the given reaction is:

Kc = [NOF]² / ([NO]² * [F₂])

Given that Kc = 7.2 × 10⁻⁴ and the initial concentrations of NO and F₂ are both 0.92 M, we can substitute these values into the equilibrium constant expression:

7.2 × 10⁻⁴ = [NOF]² / (0.92)²

Rearranging the equation and solving for [NOF], we get:

[NOF]² = 7.2 × 10⁻⁴ * (0.92)²

[NOF]² = 6.386 × 10⁻⁴

[NOF] = √(6.386 × 10⁻⁴)

[NOF] ≈ 0.067 M

Therefore, the equilibrium concentration of NOF is approximately 0.067 M when the reaction starts with initial concentrations of 0.92 M for both NO and F₂.

The reaction that is not a reduction-oxidation reaction is:

c) Li + Cl2 -> LiCl.

The transfer of electrons from one substance to another is the foundation of a reduction-oxidation (redox) reaction. Lithium (Li) loses an electron to chlorine (Cl2) in this reaction, resulting in lithium chloride (LiCl). However, because neither lithium nor chlorine changes its oxidation state, this reaction is not considered a redox reaction.

On the other hand, all the other options involve the transfer of electrons from one substance to another, indicating a redox reaction.

a) AgNO3 + NaCl -> AgCl + NaNO3: In this reaction, silver (Ag) gains an electron to reduce from Ag+ to Ag, while chlorine (Cl) loses an electron to oxidize from Cl- to Cl2.

b) CH4 + O2 -> CO2 +H2O: In this reaction, carbon (C) loses electrons to oxidize from -4 to +4, while oxygen (O) gains electrons to reduce from 0 to -2.

d) NaClO3 -> NaCl + O2: In this reaction, chlorine (Cl) loses electrons to reduce from +5 to -1, while oxygen (O) gains electrons to reduce from +6 to -2.

Explanation:

I don't really have an explanation

As the electrons gets closer to the nucleus, by the electrostatic force of attraction electrons are tightly bound to the nucleus. To move the inner electron to outer shell, high energy have to applied to weaken the nuclear force.

Nuclear force is the force by which the nucleon are bind in the nucleus and electrons are attracted towards the nucleus. The positively charged protons inside the nucleus electrostatically attracts the negatively charged electrons.

The minimum amount of energy required to remove an electron from the valence shell by overcoming the nuclear force is called ionization energy.

To bring an electron which is closer to the nucleus to the outer shell needs much energy to reduce the nuclear attractive pull. The energy need to gain.
