Answer : The correct option is, (C) a carbon chain with a carbonyl group bonded to one end.

Explanation :

An aldehyde is an organic compound which contain a functional group with (-CHO) i.e R-CHO

R-CHO functional group consists of a carbonyl center that means a carbon which is double-bonded to the oxygen. The carbon of this carbonyl group bonded with the hydrogen to one end and a carbon chain, (R) to another end.

Some examples of an aldehydes are formaldehyde $(HCHO)$ , acetaldehyde $(CH_3CHO)$

Therefore, the correct answer is, (C)

The complete orbital notation diagram of an atom is shown.

Yuki888 [10]

Answer:

Explanation:

From the description provided by the statement of the problem, we can easily solve for the values of the angular momentum quantum number.

Let us represent the atom as J:

In atom J, we have five sub-orbitals in which there 9 electrons. From the designation used to represent sublevels, we can write the notation as below:

J = 10 electrons = 1s² 2s² 2p⁵

The s-sublevel can only contain 2 electrons

p-sublevel can contain 6 electrons but we have just 5 electrons in there.

Now, to find the angular momentum quantum number, we need to understand what this quantum number denotes.

This quantum number is also known as azimuthal or secondary quantum number. It gives the shape of the orbitals in subshells accomodating electrons. This quantum number is designated by (l).

l (n-1) name of orbital shape of orbital

0 s spherical

1 p dumb-bell

2 d double dumb-bell

3 f complex

J = 1s² 2s² 2p⁵

where 1 and 2 coefficients are the principal quantum numbers(n).

s and p are the shape of the orbitals

For 1s², the l vaue is 0 because the electron is in the s orbital

2s² the l value is 0, 1 and the electron can be in the s or p orbitals

2p⁵ the l value is 0, 1 and the electrons can be in the s or p orbitals

The quantum number gives the shape of the orbital.

6. Compare and Contrast How are the properties of acids and bases similar? How are they different?

Acids and bases both react with water and a lot of acids and bases are soluble in nature.
Both acids and bases are electrolytes which means that they’re good conductors of electricity.
Acids and bases both produce ions in water solution.
Acids release hydrogen ions (H+) whereas Bases release hydroxide ions (OH–).

The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning th

OLga [1]

Answer:

ΔH = -162.5 kJ.

Explanation:

Hello.

In this case, we first rearrange the reactions:

ClO(g) + O₃(g) ⇒ Cl(g) + 2O₂(g); ΔH =-122.8 kJ

2O₃(g) ⇒ 3O₂(g); ΔH=-285.3 kJ

O₃(g) + Cl(g) ⇒ ClO(g) + O₂(g); ΔH= ?

Thus, we are going to use the Hess law, as an strategy to rearrange the known chemical reactions and thereby compute the enthalpy of reaction of the unknown one.

1. The first reaction must be inverted in order to obtain chlorine as a reactant in the third one, therefore, the enthalpy of reaction becomes positive:

Cl(g) + 2O₂(g) ⇒ ClO(g) + O₃(g); ΔH = 122.8 kJ

2. Second reaction remains the same:

2O₃(g) ⇒ 3O₂(g); ΔH=-285.3 kJ

Then, we add them to obtain:

Cl(g) + 2O₂(g) + 2O₃(g) ⇒ ClO(g) + O₃(g) + 3O₂(g)

Whereas we can subtract both oxygen and ozone to obtain the third one:

O₃(g) + Cl(g) ⇒ ClO(g) + O₂(g)

Therefore, the enthalpy of reaction turns out:

ΔH = 122.8 kJ + (-285.3 kJ )

ΔH = -162.5 kJ.

Best regards.
