The molecule is WAX.

What is WAX?

Waxes consist of long-chain fatty acid attached through ester oxygen to long-chain alcohol. These molecules exist completely water-insoluble and typically solid at biological temperatures.

The main objective of the waxes is to provide a water-proof layer to the feathers, but other processes have also been suggested. Some of these lipids can also recreate a role as pheromones in sexual signaling.

the characteristics of wax are-

1. Solid at room temperature; liquid at more increased temperatures.

2. Primarily hydrocarbon in design.

3. Water repellent; insoluble in water.

4. Smooth texture; buffable under slight pressure.

5. Low toxicity; low reactivity.

Answers

Answer:

2Al(NO3)3+3K2CO3->Al2(CO3)3+6KNO3

So the right answer is 2,3,1,6

Explanation:

First you look at the equation that isn't balance, you can see Al(NO3)3 while Al2(CO3)3, so you put 2 in Al(NO3)3.

Now we have 2Al is correct, but 6NO3. So we have 6KNO3, it also means we have 6K

Finally, we only have 2K as K2CO3 so we put 3 in it, so we have 3K2CO3.

Which of the forces of molecular attraction is the weakest? A London dispersion forces B hydrogen bond C single covalent bond D dipole dipole interactions

Answers

Answer: London dispersion forces of molecular attraction is the weakest.

Explanation:

The forces which exist between neighboring atoms, molecules or ions can be force of attraction or force of repulsion. These forces are called intermolecular forces.  

When ions with same charge come in contact with each other then force of repulsion is there but when ions with opposite charge comes in contact with each other then force of attraction will be there.

These forces are described as follows.

London dispersion forces: The electrostatic attraction between atoms or molecules causes a temporary induced charge on the respective atoms. These attractive forces are weak in nature and called London dispersion forces.

Hydrogen bond: When a hydrogen atom is attached to electronegative atom like fluorine, nitrogen and oxygen then bonding between these atoms is called a hydrogen bond.

Dipole-dipole interaction: When positive end of one polar molecule gets attracted by the negative end of another polar molecule then force existing between these ends is called dipole-dipole interaction.

Single covalent bond: When an atom is sharing its valence electrons with another atom then it is called a covalent bond.

Thus, we can conclude that London dispersion forces of molecular attraction is the weakest.

How much work (in J) is involved in a chemical reaction if the volume decreases from 5.20 to 1.13 L against a constant pressure of 0.852 atm ? Express your answer to three significant figures and include the appropriate units.

Answers

Answer:

W = 350.6 J

Explanation:

Given that,

The volume decreases from 5.20 to 1.13 L against a constant pressure of 0.852 atm.

The change in volume = 1.13 L - 5.20 L = -4.07 L

Work done, W = - PΔV

So,

W = 0.852 atm × -4.07 L

= - 3.46 L-atm

or

[tex]W=3.46\ L-atm\times \dfrac{101.33\ J}{1\ L-atm}\\\\=350.6\ J[/tex]

So, the required work done is 350.6 J.

Aluminum reacts with oxygen to form aluminum oxide. Select the correct unbalanced skeleton equation for this reaction. A. Al(s) + 0(g) - AIO(s) B. Al203(s) - Al(s) + 02(8) C. Al(s) - 02(8) + Al203(s) D. Al(s) + 02(8) - Al203(s)

Answers

Answer:

D. Al(s) + O₂(g) → Al₂O₃(s)

Explanation:

Aluminum is a solid metal, so it is written as Al(s).

Oxygen is a diatomic gas, so we write this compound as O₂(g).

Aluminum oxide has the formula Al₂O₃ because in oxides the oxidation number of oxygen atom is -2 and for aluminum, the oxidation number is 3. Thus, we write this compound as Al₂O₃(s).

Now, we have to found the chemical equation in which the reactants (left side) are Al(s) and O₂(g) while the product (right side) is Al₂O₃(s). From the options, we can see that the correct is (D):

Al(s) + O₂(g) → Al₂O₃(s)

Explanation:

Deuterium is the products of a hydrogen fusion reaction, the correct option is A.

What is hydrogen fusion?

It is the situation in which two hydrogen atoms merge or coalesce to form a helium atom.

A portion of the hydrogen's mass is transformed into energy during the process.

The fusion reaction that abilities the Sun and stars occurs when hydrogen atoms merge to produce deuterium, and then deuterium and hydrogen atoms fuse to form helium, releasing energy.

Four Hydrogen nuclei (protons) combine to form a Helium nucleus in the basic Hydrogen fusion cycle.  

Actually, electrons, neutrinos, and photons are involved in the hydrogen fusion into helium.

Since the total mass of the eventually results single nucleus is lower than the mass of the original two nuclei, the process releases energy.

Thus, the correct option for the given case is A.

In a solution containing 21.2 g sodium carbonate in 1.50 L of solution, calculate
the concentration of the sodium and carbonate ions.

Answers

Answer:

0.13 molL-1

Explanation:

We must first obtain the number of moles of sodium carbonate as follows;

Number of moles = mass/molar mass

Number of moles = 21.2 g/106 g/mol

Number of moles= 0.2 moles

Number of moles = concentration × volume

Volume = 1.50 L

Concentration = number of moles/volume

Concentration = 0.2 moles/1.5 L

Concentration = 0.13 molL-1

When naming a molecule, how do you indicate that the carbons on either side
of the double bond are pointing in opposite directions?

Answers

Answer:

use the prefix trans-

When naming a molecule, we indicate that the carbons on either side of the double bond are pointing in opposite directions by adding a prefix (-trans) in the name of the molecule.

What is IUPAC nomenclature?

IUPAC nomenclature of organic compounds refers to the systematic approach taken for the nomenclature of organic compounds as per the recommendation of the International Union of Pure and Applied Chemistry.

If alkenes have two different substituents at each end of the C=C then they can exist as stereoisomers (as geometric isomers).

This is because there is restricted rotation of the double bond due to the pi bond which means they don't readily interconvert.

cis- if the two alkyl groups, R-, are on the same side of the C=Ctrans- if the two alkyl groups, R-, are on opposite sides of the C=C.

Therefore, When naming a molecule, we indicate that the carbons on either side of the double bond are pointing in opposite directions by adding a prefix (-trans) in the name of the molecule.

the name of the compound made from lithium chloride and oxygen​

Answers

Answer:

Lithium perchlorate

Explanation:

The compound formed from lithium chloride and oxygen is lithium oxide (Li₂O).

When lithium chloride (LiCl) reacts with oxygen (O₂), they combine to form lithium oxide (Li₂O). In this reaction, each lithium-ion (Li⁺) from lithium chloride combines with an oxygen atom (O) from oxygen gas to form a lithium oxide molecule.

The chemical formula Li₂O indicates that two lithium ions are combined with one oxygen atom in the compound. This is because lithium has a +1 charge, and since there are two lithium ions, their combined charge is +2. Oxygen, on the other hand, has a -2 charge, so one oxygen atom is sufficient to balance the charges and form a neutral compound.

Hence, the name of the compound formed is Li₂O

What is the two major types of chemical bonding?

Answers

Answer:

Ionic bond and covalent bond

Explanation:

The two main types of chemical bonding are ionic bond and covalent bond.

In an ionic bond, there is a transfer of electrons from one atom to another. Usually from a metal to a nonmetal leading to the existence of an ion pair. Ionic compounds are soluble in water and have high melting and boiling points due to the strong electrostatic interaction between ions in the compound.

A covalent bond involves sharing of electrons between atoms. In an ordinary covalent bond, the shared electrons are furnished by the two bonding atoms while in a dative covalent bond, the two bonding electrons are furnished by only one of the bonding species.

What is the molecular formula of the compound CH2 with molar mass = 42.0 g/mol? A. C2H18 B. C2H4 C. CAHg O D. C3H6​

Answers

The molecular formula of the compound CH2 with molar mass = 42.0 g/mol is C₃H₆. Therefore, option D is correct.

What is molar mass ?

The term molar mass is defined as the mass in grams of one mole of a substance. The units of molar mass are grams per mole, abbreviated as g/mol.

First, let's find the molar mass of CH₂.

The molar mass CH₂= 12.0 + (2 x 1.01)

= 14.02 g/mol

Now to determine the molecular formula, we need to find the ratio based in the molar masses.

42 / 14.02

= 2.99

≅ 3

Therefore, the ratio is 3, the molecular formula is C₃H₆.

Thus, option D is correct.
