Which type of soil would likely drain water the fastest?

Answers

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.

Due to this reason, sandy soil is usually used in filtration process.

Acetone, (CH3)2CO, has 3 sp3 hybridized carbon atoms and 1 sp2 hybridized oxygen atom, according to VSEPR theory. The carbon atoms are tetrahedral and oxygen atom is trigonal planar in shape.

i) Using VSEPR theory, we can predict the arrangement of electron pairs around the atoms in a molecule. The Lewis structure of acetone shows that the carbon atoms have four electron pairs around them (two from the single bonds and two from the double bond) and the oxygen atom has two electron pairs around it.

The carbon atoms are all sp3 hybridized, and the oxygen atom is sp2 hybridized.

ii) The three carbon atoms in acetone each have four electron pairs around them, which means they are tetrahedral in shape. Therefore, they are all sp3 hybridized.

Answers

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

How do I determine the number of mole of Al₂O₃ formed?

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

Given :

T = half life of cobalt-60

= 5.3 years

λ = decay constant for cobalt-60 = ?

decay constant is given as follows

λ = 0.693 / T

Substituting the given values

λ = 0.693/5.3

= 0.131

N₀ = initial amount of cobalt-60

= 10 g

t = time of decay

= 21.2 years

N = final amount of cobalt-60 after time "t"

final amount of cobalt-60 after time "t" is given as

N = N₀

Substituting given values

N = 10

N = 10 x 0.0622 g

N = 0.63 g

How to find partial pressure from mole fraction and total pressure?

Answers

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

How to calculate partial pressure using an example?

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

Fe(s) + Cl₂ (g) → FeCl3 (s)

How many grams of iron(III) chloride (FeCl3) result when 15.5 g of iron (Fe) is reacted with an excess of chlorine gas? Balance the equation first.​

Answers

When 15.5 g of iron (Fe) is reacted with an excess of chlorine gas, it will produce approximately 44.97 g of iron(III) chloride (FeCl₃) based on the balanced equation.

To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides. In the unbalanced equation:

Fe(s) + Cl₂ (g) → FeCl₃ (s)

We have one iron atom on the left side and one iron atom on the right side. So, the iron is already balanced. However, we have two chlorine atoms on the left side and three chlorine atoms on the right side. To balance the chlorine, we need to place a coefficient of 3 in front of the Cl₂ on the left side:

Fe(s) + 3Cl₂ (g) → FeCl₃ (s)

Now that the equation is balanced, we can calculate the number of grams of iron(III) chloride (FeCl₃) formed when 15.5 g of iron (Fe) reacts. From the balanced equation, we can see that the molar ratio between iron and iron(III) chloride is 1:1. Therefore, the molar mass of iron(III) chloride is relevant for this calculation.

The molar mass of Fe is approximately 55.845 g/mol, and the molar mass of FeCl₃ is approximately 162.204 g/mol (55.845 g/mol for Fe + 3 * 35.453 g/mol for Cl). We can use these molar masses to convert the mass of iron to moles and then calculate the mass of iron(III) chloride produced.

Number of moles of Fe = 15.5 g / 55.845 g/mol = 0.2776 mol

Since the molar ratio between Fe and FeCl₃ is 1:1, the number of moles of FeCl₃ produced is also 0.2776 mol.

Mass of FeCl₃ = 0.2776 mol * 162.204 g/mol = 44.97 g

Therefore, 15.5 g of iron will result in approximately 44.97 g of iron(III) chloride when reacted with an excess of chlorine gas.

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

Moles of water = 0.700

The molar water (H₂O) mass = 18 g/mol
