The mass of manganese dioxide produced from one mole or 18 g of water is 174 g. Then, MnO₂ produced from 445 gram of H₂O is 4300 g.

Permanganate MnO₄ is an ion from potassium permanganate. It is an oxidizing agent.  MnO₄  easily reduces to MnO₂. As per the given reaction, 18 g is required by one mole or 174 g of MnO₂.

Molar mass of MnO₂ = 87 g/mol

molar mass of water = 18 g/mol

mass of 2 moles of MnO₂ = 174 g

Thus, 18 g of water gives 174 g of MnO₂.

Mass of MnO₂ produced from 445 g of  water = (445 × 174)/18 = 4300 g

Therefore, the mass of MnO₂ produced is 4300 g.

The elements highlighted in red have the same number of electron shells

in common. The correct answert is D.

A row of chemical elements makes up a period in the periodic table. The number of electron shells is the same for every atom in a row. Periods are the horizontal divisions or rows in the periodic table, and groups are the vertical divisions or columns.

Periods are shown in the table from top to bottom, numbered 1 through 7. Because they have the same number of orbitals, elements with the same period have identical masses but different characteristics. In other words, the electrons on the same outermost level, which is precisely the number that distinguishes each period, are a characteristic of the elements of a certain period. For instance, the third period elements have electrons up to level three.The number of the energy level increases as the periodic table's period numbers do.

The items with a red highlight share the trait of being from the same period, which is period two. As a result, electrons can now reach level 2.

When benzene has both a strong and weak activator group, only the strong activator guides the electrophile towards ortho or para to the that activator group.

Because they lack an electron, electrophiles can receive a pair of electrons from organisms that have an abundance of them. Examples include carbonyl compounds and carbocations. A nucleophile is a species that has an abundance of electrons and gives electron pairs to species that lack electrons. Carbanions, water, ammonia, cyanide ions, and others are examples.

A chemical species known as an electrophile in chemistry accepts an electron pair from nucleophiles to form bonds with them. Electrophiles are Lewis acids because they are electron-accepting molecules.

To find partial pressure from mole fraction, we have to multiply mole fraction with total pressure in the event.

The formula for partial pressure is expressed as Pfraction = molefraction x Ptotal. Partial pressure is the result of multiplying the mole fraction by the total pressure. Let's look at the example below to make it simpler for you to understand:

Consider a chamber with 2.611 atm of pressure, 24.2 g of He, and 4.32 g of O₂. In this instance, we must first get the mole fraction before calculating the partial pressure.

24.2 g Neon x 1 mol Neon / 20.18 g Neon = 1.199 mol Neon

4.32 g Oxygen x 1 mol Oxygen / 31.998 g O₂ = 0.135 mol Oxygen.

Total moles =  1.199 x 0.135 = 1.334 mol gas

Mole fraction Ne = 1.199 mol/1.334 mol = 0.899

Mole fraction O₂ = Oxygen: 0.135/1.334 = .101

Then find the partial pressure

PNe = mole fraction Ne x Ptot = 0.899 x 2.611 atm = 2.35 atm

PO2 = mole fraction O ₂ x Ptot = 0.101 x 2.611 atm = 0.264 atm

The number of mole of Al₂O₃ formed when 4.0 moles of O₂ reacts, given the reaction is 2.67 moles

From the given stoichiometry of the reaction (i.e 6.0 moles of Al reacts with 4.0 moles of O₂ to form Al₂O₃), we can see that O₂ is the limiting reactant.

Knowing that O₂ is the limiting reactant we can easily determine the number of moles of Al₂O₃ formed when 4.0 moles of O₂ reacts as follow:

4Al + 3O₂ -> 2Al₂O₃

From the balanced equation above,

3 moles of O₂ reacted to produce 2 moles of Al₂O₃

Therefore,

4 moles of O₂ will react to produce = (4 moles × 2 moles) / 3 moles = 2.67 moles of Al₂O₃

Thus, we can conclude from the above calculation that the number of moles of Al₂O₃ formed is 2.67 moles

The mass in grams of 0.700 moles of water (H₂O) = 12.6g/mol (option C)

The mass of a chemical in a mole is known as its molar mass.

It is the total atomic mass of every element that is present in that molecule. The molar mass unit is g/mol.

Determine the molar mass of the water(H₂O):

Molar masses of 1 g/mol of hydrogen and 16 g/mol of oxygen make up a mole.

The chemical formula for water is H₂O.

The water's molar mass is thus:

H₂O = (2 x 1) + 16

= 18 g/mol

Moles of water = 0.700

The molar water (H₂O) mass = 18 g/mol

Object's mass is determined by:

m = (moles of the sample) x (molar mass of the compound)

According to this concept of replication, the double helix's two strands separate during the replication process and each one acts as a template from which the next complimentary strand is copied.

Each of the two strands that make up the double helix acts as a template from which new strands are copied during DNA replication. The parental or "old" strand and the new strand will complement one another. One new daughter strand and one new parental strand make up each new double strand.

Sandy soil would likely drain water the fastest.

Soil is composed of minerals, organic matter, water and gas. It is divided into three classes viz. sand, silt and clay.

The ability of a soil to absorb or drain water depends upon the pore size of the soil particles.

In case of clayey soil, the pore size is comparatively large than sandy soil so clayey soil will absorb the water molecules in its pores .On the other hand, the pore size of sandy soil is relatively small, so it cannot retain the water in its pores, hence it can drain water easily.
