Which type of isomers are o-xylene, m-xylene, and p-xylene?

structural isomers
optical isomers
geometric isomers

Answers

Answer 1

o-xylene, m-xylene, and p-xylene are structural isomers.

o-xylene, m-xylene, and p-xylene are examples of aromatic isomers, also known as ortho-, meta-, and para-xylene, respectively. These isomers are classified as aromatic because they are part of a family of compounds known as aromatic hydrocarbons, which contain a ring of six carbon atoms bonded to each other in a specific way.

o-xylene, m-xylene, and p-xylene are also examples of structural isomers. Structural isomers are compounds that have the same molecular formula but differ in the arrangement of their atoms. In the case of o-xylene, m-xylene, and p-xylene, the atoms are arranged differently around the ring of six carbon atoms.

o-xylene, m-xylene, and p-xylene are not optical isomers, which are also known as enantiomers. Optical isomers are compounds that are mirror images of each other but are not superimposable. Optical isomers are important in medicinal chemistry because they can have different biological properties even though they have the same molecular formula and structure.

o-xylene, m-xylene, and p-xylene are also not geometric isomers. Geometric isomers are compounds that have the same molecular formula and the same arrangement of atoms, but differ in the orientation of their atoms or groups of atoms in space. Geometric isomers are often found in compounds with cis-trans double bonds or ring structures.

Which of the following concentration measures will change in value as the temperature of a solution changes?
1. mass percent
2.mole fraction
3. molality
4. molarity
5. all of these

Answers

The concentration measures will change in value as the temperature of a solution changes is molarity. The correct option is 4.

What is molarity?

The molarity of a substance refers to how much of it is present in a given volume of solution (M). Molarity is the measure of how many moles of a solute are present per liter of a solution. Molarity is also referred to as a solution's molar concentration.

To find the equation for molarity, divide the volume of solvent used to dissolve the given solute by the number of moles of that solute. M = n V

Since the volume of the solution rises as the temperature rises, molarity decreases. Therefore, molarity is normally affected when therefore is a change in temperature of a solution either when it increases or decreases.

Are magnesium and calcium more reactive with oxygen in the air than is aluminum? Support your answer.

Answers

Magnesium and calcium are 2nd group elements with 2 valence electrons. They are metals in room temperature and easily lose these electrons to nonmetals such as oxygen.

What is magnesium ?

Magnesium is 12th element in periodic table. It is 2nd group element and is a called alkaline earth metals. Its group members are calcium, strontium, and barium.

They contains 2 valence electrons which can be easily lost to a non-metal. Oxygen is highly electronegative element and it contains 6 valence electrons and need two more electrons to achieve octet.

Al is 13th group element it is not as much electropositive as alkaline earth metals. It contains 3 valence electrons and thus it need to lose all these 3 electrons to achieve octet. Hence, Al is less reactive towards O2 in comparison with Mg and Ca.

ammonium ion (nh4 ) is an acid that can dissociate to form ammonia (nh3) and h in aqueous solution. the pka for this reaction is 9.25. when total ammonium ion is 50% dissociated, what is the ph?

Answers

When total ammonium ion is 50% dissociated, The pH is 9.25.

Given, the pKₐ of ammonium ion (NH₄⁺) is 9.25.

The dissociation of NH₄⁺ to ammonia (NH₃) and H⁺ in aqueous solution is represented below.

It is stated that the ammonium ion is 50% dissociated in the solution. Therefore the concentration of each species at that instant [if started with 1M conc. of NH4+ (aq)] is summarized as follows:

                                              NH4+ (aq) ⇌ NH3 (aq) + H+ (aq)

Initial conc. (in M)                     1                   -                 -

At 50% dissociation 1-0.5, i.e., 0.5          0.5          0.5

The given value of pKₐ immediately reminds us of the form of Henderson-Hasselbalch equation containing pKₐ , i.e.,

pH = pKₐ + log₁₀ [tex]\frac{[salt]}{[acid]}[/tex]  _ _ _(i)

But, NH₄⁺ (aq) exists as the conjugate acid form, as well as the salt (ionized) form. Hence, we cannot use equation. (i) for our calculations.

Therefore, we need to convert the above value of Kₐ to the equivalent Kb (for NH₃), corresponding to the reverse equilibrium.

This is achieved by using the relation

Kb = [tex]\frac{Kw}{Ka}[/tex]

or,  -log₁₀ Kb = -log₁₀ Kw + log₁₀ Ka

or,  pKb = pKw - pKa = 14 - 9.25 = 4.75

where, pKw = 1 x 10⁻¹⁴ (at 298 K).

Therefore, pKb of ammonia (NH₃) = 4.75

Now, we need to use the form of Henderson-Hasselbalch equation which uses Kb; which is in fact

pOH = pKb + log₁₀ [tex]\frac{[salt]}{[base]}[/tex]  _ _ _(ii)

where the salt is NH₄⁺, and the base is NH₃. Further, we know that

Kw = [H⁺][OH⁻]  or,  pOH + pH = pKw = 14    or,   pOH = 14 - pH

Substituting this relation in eq. (ii) gives

14 - pH = pKb + log₁₀ [tex]\frac{[NH4+]}{[NH3]}[/tex]

or, pH = 14 - pKb — log₁₀ [tex]\frac{[NH4+]}{[NH3]}[/tex]

As calculated, pKb = 4.75, [NH₄⁺] = 0.50 M, while [NH₃] = 0.50 M, assuming we start with a conc. of 1M NH₄⁺. Hence,

pH = 14 – 4.75 – log₁₀ [tex]\frac{0.50}{0.50}[/tex]

     = 9.25 - log₁₀ ( 1 )

     = 9.25 - 0

pH = 9.25

Hence, the pH of a solution consisting of 50% NH₃ and 50% NH₄⁺ will be equal to 9.25.

what quantity is needed to convert between the moles of a given sample of a substance and its mass in grams

Answers

The molar mass of the substance is needed to convert between the moles of a given sample of a substance and its mass in grams.

What is molar mass?

A compound's molar mass, which is measured in grams per mole, specifies how much of a given material weighs in one mole. In other terms, the molar mass is the sum of the masses of all the atoms that make up a mole of a certain molecule, expressed in grams. As a result, the molar mass is measured in grams/mole.

The compound's molar mass is expressed in grams per mole, or g/mol. The mass of 1 mol, expressed in the SI as g/mol, is the definition of the molar mass. Example: Water has a molar mass of 18.016 g/mol.

Thus, The molar mass of the substance is needed to convert between the moles of a given sample of a substance and its mass in grams.

which set of elements is arranged in order of increasing electronegativity? which set of elements is arranged in order of increasing electronegativity? ga < ge < p < n p < n < ge < ga ge < n < ga < p n < p < ge < ga

Answers

The electronegativity is n < p < ge < ga.

What is electronegativity?

Electronegativity is a measure of an atom's ability to attract electrons when it forms a chemical bond with another atom. It is based on the Pauling Scale, which assigns values to elements based on their tendency to attract electrons when they form bonds. Electronegativity increases from left to right across the periodic table, and increases from the bottom to the top of the periodic table.

The correct answer is n < p < ge < ga. This is because electronegativity increases as we move down a group in the periodic table and from left to right across a period.
Therefore, the element with the highest electronegativity is at the bottom right corner of the periodic table, which is gaseous, followed by Germanium, Phosphorus, and then Nitrogen.
