Be as explicit as you can in describing how the covalent bond between an atom of Chlorine and an atom of Iodine forms. (What happens to the electrons, which electrons are involved, and what allows this to happen MUST all be part of your answer to receive full credit.)

Answers

Answer 1

When two atoms of chlorine and iodine join together to form a covalent bond, their outermost electrons interact to form a chemical bond.

What is a Covalent bond?

A covalent bond is a type of chemical bond that involves the sharing of a pair of electrons between two atoms. Covalent bonds are formed when two atoms come together to share their electrons in order to reach a more stable electron configuration. As a result, the two atoms become bonded together by the attraction of their shared electrons.

The chlorine atom has seven valence electrons, while the iodine atom has seven as well. Both atoms will want to complete their octets, so the two atoms share their outermost electrons with each other. During the formation of the covalent bond, the chlorine atom will donate one of its electrons to the iodine atom, while the iodine atom will donate one of its electrons to the chlorine atom. This sharing of electrons allows the two atoms to form a single bond and fill their octets, forming a covalent bond.

When calcium carbonate is heated, it breaks down into the components  calcium oxide and carbon dioxide.

What do you mean by calcium carbonate?

Calcium carbonate is a chemical compound that has the formula CaCO3. It is a common mineral found in rocks as calcite and aragonite, and it is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is a component of agricultural lime that is formed when calcium ions in hard water react with carbonate ions to form limescale. It's commonly used in medicine as a calcium supplement or an antacid, but too much of it can be dangerous.

25 g of calcium carbonate contains 25/100 x (40 + 12 + 3 x 16) = 25/100 x 88 = 22 g of calcium and 12 g of carbon.

What is the molecular formula of a compound that has an empirical formula of CH2O and a molar mass of 120.12 g/mol

Answers

The molecular formula of a compound that has an empirical formula of CH₂O and a molar mass of 120.12 g/mol is C₄H₈O₄.

A molecular formula shows the number of different types of atoms that are present in a molecule whereas an empirical formula represents the simplest whole number ratio of the different atoms present in a molecule.

Given,

empirical formula= CH₂O

molar mass = 120.12 g/mol

To find: molecular formula

we know that,

atomic mass of carbon= 12 g/mol

atomic mass of hydrogen= 1g/mol

atomic mass of oxygen= 16 g/mol

molar mass of CH₂O

= (12+ 1×2 + 16) g/mol

=30 g/mol

therefore, molecular formula

⇒(CH₂O )n = 120.12

⇒30 n= 120.12

⇒n=120.12/30

⇒n= 4.004

⇒n≈4

Thus,

(CH₂O )n = (CH₂O )4 =C₄H₈O₄

Hence, molecular formula is C₄H₈O₄

What is decomposition reaction?

Chemical decomposition, also known as chemical breakdown, is the process of breaking down a single chemical entity into two or more components. Chemical breakdown is commonly thought of and characterized as the inverse of chemical synthesis. When one reactant breaks down into two or more products, this is referred to as a decomposition reaction. This is expressed by the following generic equation: AB A + B. The breakdown of hydrogen peroxide to water and oxygen is an example of a decomposition process, as is the breakdown of water to hydrogen and oxygen.

Here,

In airbags, sodium azide decomposes to form sodium and nitrogen gas, which inflates the bag. The decomposition reaction is:

2 NaN₃ ⇒ 2 Na + 3 N₂

We can calculate the mass of NaN₃ needed to produce 11.5 L of N₂ at STP, using the following relations.

At STP, 1 mole of N₂ occupies 22.4 L.

The molar ratio of N₂ to NaN₃ is 3:2.

Why do the fourth and fifth periods contain 18 elements rather than 8 as observed in the second and third periods?

The fourth and fifth periods contain 18 elements rather than 8 as observed in the second and third period because of the accommodation of 10 additional electrons in the 3d orbital.

The number of orbitals that can be accommodated by s subshell is one, p subshell is three, d subshell is five and f subshell is seven.

In the second and the third period, the 2s subshell is filled with two electrons, 2p subshell with six electrons .So, the second period contains eight elements. The sequence in third period is similar to that of second period with additional filling of 3s and 3p subshell.

In the fourth period, electrons are first filled in the 4s subshell, only after that they can be filled in the 3d subshell. So, fourth period contains 18 elements , which is due to the additional 10 electrons in 3d subshell. This is similar in the case of fifth period also.

Avogadro's number (6.022 x 1023) of molecules (or formula units) make up one mole of a substance (ionic compound). The mass of 1 mole of a chemical is indicated by its molar mass. It provides you with the number of grams per mole of a substance, to put it another way.

ΔT = Kc*W*i

Kc = cryoscopy constant of the solute X

W = molality of the solution

i = van't Hoff factor, For organic molecules, such as alanine, i = 1.

n = 45.8/89.09

n = 0.5141 mol

W = 0.5141/1.2 = 0.4284 mol/kg

So, Kc of X is:

4.10 = Kc*0.4284*1

Kc = 9.57 °C.kg/mol

So, if now sodium chloride is added to X, and the temperature change is the same, and i = 1.82:

4.10 = 9.57*W*1.82

W = 0.2354 mol/kg

The number of moles of the solute is then:

W = n/1.2

0.2354 = n/1.2

n = 0.2825 mol

The molar mass of sodium chloride is 58.44 g/mol, thus the mass is the molar mass multiplied by the number of moles:

m = 58.44*0.2825

m = 16.5 g

Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones.

Newton's law of motion that act upon the vehicles at the point of impact is the second law of motion.

Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum that is produced. Mathematically, we have;

Where;

m = The mass of the object

v = The final velocity of the object

u = The initial velocity of the object

Δt = The duration of motion of the object during change in velocity

Therefore, given that the mass, 'M', of the truck is larger than the mass, 'm', of the minivan, where the time of change in velocity Δt, and the initial and final velocities of both automobiles are the same such as in a sudden stop, the garbage ruck will exert more force than the minivan, and therefore, the garbage truck has a greater initial momentum before the automobiles are brought to a stop.

Two amino acids, aspartic acid and phenylalanine, make up the low-calorie sweetener known as aspartame. In addition to being present in tabletop sweetener packets, aspartame is a common component used to substitute sugar in low-calorie foods and beverages.

Here there are 4.50 mg of aspartame.

First, the mass is converted from mg to g by:

1 g = 1000 mg

So, 1 mg = 0.001 g

So, 4.5 mg = 4.5 × 10⁻³ g

Molar mass of aspartame = 294.40 g/mol

So, Number of moles of aspartame = [tex]\frac{Given mass}{Molar mass}[/tex]

or, n = 4.5 × 10⁻³ / 294.3
