Explain how the molecular structure of soap allows it to clean many types of stains. What is a micelle? What is emulsification? How does soap work? Your answer should include a diagram of a micelle, and a discussion of polarity and intermolecular attractions. please write everything asked to be included in the response!! i am giving many points for this so please answer everything.

Answers

Answer:

1. The soap molecule is made up of two different ends that include polar head which is hydrophilic carrying carboxylate group (-CO2) (binds with water) and the other is non-polar hydrocarbon tail that is hydrophobic carrying hydrocarbon chain (binds with stain) .

When soap water is added with stain or oil, soap molecules form micelles which are the tiny clusters of soap molecules representing hydrophilic head  (water-loving) points outwards that sticks to the water and hydrophobic tail (oil-loving) points inwards that stick to the oil and trap oil in the center.

As micelle is soluble in water, the trapped oil or stain is rinsed away along with soapy water.

2. A micelle is defined as a cluster of surfactant molecules that are dispersed water and form a colloidal solution.

3. Emulsification is the process in which soap act as an emulsifier that allows dispersion of immiscible liquid. It means soap will disperse stain or dirt in such a way that it can be removed.

4. As we discussed earlier, Soap has hydrophilic (water-loving) carboxylate group (-CO2) that form hydrogen bonds and ion-dipole interactions with water and the hydrophobic (water-fearing) tail carry nonpolar hydrocarbon chain that interacts with a stain by forming micelles through dispersion force.

The negatively charged carboxylate group (hydrophilic) repels each other and hydrocarbon chain (hydrophobic) trap stain inside and remove the dirt along with water.

. Se dispone de una muestra impura de aluminio de 50g. Se hace reaccionar con sulfú rico para encontrar su riqueza. Hallar la riqueza sabiendo que se obtienen 28g de sal.

Answers

Answer:

9.32% de riqueza de Al en la muestra

Explanation:

La reacción de aluminio (Al) con ácido sulfúrico (H₂SO₄) es:

2 Al + 3 H₂SO₄ → Al₂(SO₄)₃ + 3 H₂

Dos moles de aluminio reaccionan con 3 moles de ácido sulfúrico para producir una mol de sulfato de aluminio (Sal).

Las moles de 28g de sulfato de aluminio (Masa molar: 324.15g) son:

28g ₓ (1 mol / 324.15) = 0.0864 moles de Al₂(SO₄)₃

Así, las moles de aluminio que reaccionaron fueron:

0.0864 moles de Al₂(SO₄)₃ ₓ ( 2 moles Al / 1 mol Al₂(SO₄)₃) =

0.1728 moles de Al. En gramos (Masa atómica: 26.98g/mol):

0.1728 moles Al ₓ (26.98g / mol) = 4.66g de aluminio.

Así, la riqueza de la muestra es:

4.66g Al / 50g muestra ₓ100 = 9.32% de riqueza de Al en la muestra

Estimate the freezing point depression of 0.19
m C12H22O11(aq). The freezing point constant of water is 1.86 K · kg/mol.
Answer in units of ◦C.

Answers

Answer:

0.3634 °C

Explanation:

In this question, we are tasked with calculating the freezing point depression of 0.19 M C12H12O11( sucrose)

Mathematically this can be calculated using the formula;

ΔTf = i * kf * m

where ΔTf is the freezing point depression

i is Van’t Hoff factor

kf is the molal freezing point depression for the solvent

m is the molality of the solution

From the question we identify the following;

Since sucrose is a non-electrolyte, i = 1 ( i refers to the number of moles of particles obtained when 1 mol of solute dissolves)

m is 0.19

kf = 1.86

substituting these values into the equation, we have

ΔTf = 1 * 1.86 * 0.19 = 0.3534 °C

What is the concentration of a solution with a volume of 660L that contains 33.4g of AlCO3?

Answers

Answer:

The concentration of the solution is 5.8168 × [tex]10^{-4}[/tex] mol.[tex]dm^{-3}[/tex]

Explanation:

Here, we want to calculate the concentration of the solution.

The unit of this is mol/dm^3

So the first thing to do here is to calculate the number of moles of the solute present, which is the number of moles of AlCO3

The number of moles = mass/molar mass

molar mass of AlCO3 = 27 + 12 + 3(16)  = 27 + 12 + 48 = 87g/mol

Number of moles = 33.4/87 = 0.384 moles

This 0.384 moles is present in 660 L

x moles will be present in 1 dm^3

Recall 1 dm^3 = 1L

x * 660 = 0.384 * 1

x = 0.384/660 = 0.00058168 = 5.8168 * 10^-4 mol/dm^3

For propanoic acid, there are 3 atoms of C, 6 atoms of H and 2 atoms of oxygen.

A) CH2CHCOOH . Here you have 3 atoms of C but 4 atoms of H. That means this compound is not an isomer.

B) CH3CH2CH2COOH . Here, there are 4 atoms of C. Thus, is not an isomer.

C) CH3CH(OH)CH2OH. This structure has 3 atoms of C, but 8 atoms of H. Thus, is not an isomer.

D) HCOOCH2CH3. Here, there are 3 atoms of C, 6 atoms of H and 2 atoms of O. Thus, this structure is an isomer of propanoic acid.

Answer:

D) HCOOCH2CH3

Explanation:

Option D is an isomer of propanoic acid because this compound has the same number of atoms as the acid; 3 carbons, 6 hydrogens and 2 oxygen. They may differ in some properties but their main difference must be their molecular structure, that is, the arrangement of their atoms.

9. Determine the number of protons, neutrons, and electrons in one 'H' ion. Explain how you found your

'H' ion has only one proton and do not have any electron and neutron.

Explanation:

Hydrogen atom has only one electron and one proton and when it loses that electron, hydrogen ion (H+) is formed which is positively charged (charge of +1) and referred as a proton.

So, hydrogen ion do not left with any electrons or have zero electrons.

Hydrogen (H) atom do not have any neutrons in its tiny nucleus, so hydrogen ion (H+) also do not have neutrons.

Hence, 'H' ion (H+) has only proton and zero electron and neutron.

Oxygen is in group 6 which means it holds 6 valence electrons, leaving 2 for bonds.

A valence electron is an outer shell electron that can form a chemical bond if the outer shell is not closed.

Now when an atom bonds to another in a single bond, both atoms contribute one valence electron in order to form a shared pair.

In the picture O has 7 Valence electrons, so it would have a negative charge of 1.

The middle Hydrogen has 3 valence electrons which would make hydrogen have a charge of negative 1.

Explanation:

H2S + HNO3 ----->  NO + H2O + S

There are 3 O's on left and  only 2 on right so  put 2 before NO:

H2S + HNO3 ----> 2NO + H2O + S

Now we have 2 N's on left so put 2 before HNO3:

H2S + 2HNO3 -----> 2NO + H2O + S

4 H's on the left so

H2S + 2HNO3 -----> 2NO + 2H2O + S

That makes 6 O's on left so  we write

H2S + 2HNO3 ----> 2NO + 4H2O + S

Now there 8 H's on the right but only 4 on the right so we adjust H2S and S:

3H2S + 2HNO3 -----> 2NO + 4H2O + 3S

Now it balances!

O C. Satellite
O D. Satellite D

Answers

Answer:

Option C. Satellite C.

Explanation:

The gravitational pull of the earth talls about the weight of an object.

To know which of them has the greatest gravitational pull, let us determine the weight of each satellite.

For satellite A:

Mass = 500Kg

Acceleration due to gravity (g) = 9.8m/s²

Weight (W) =.?

Weight (W) = mass (m) x Acceleration due to gravity (g)

W = m x g

W = 500 x 9.8

W = 4900N

For satellite B:

Mass = 400Kg

Acceleration due to gravity (g) = 9.8m/s²

Weight (W) =.?

W = m x g

W = 400 x 9.8

W = 3920N

For satellite C:

Mass = 700Kg

Acceleration due to gravity (g) = 9.8m/s²

Weight (W) =.?

W = m x g

W = 700 x 9.8

W = 6860N

For satellite D:

Mass = 600Kg

Acceleration due to gravity (g) = 9.8m/s²

Weight (W) =.?

W = m x g

W = 600 x 9.8

W = 5880N

Satellite >> Mass >>> Gravitational pull

A >>>>>>>> 500Kg >> 4900N

B >>>>>>>> 400Kg >> 3920N

C >>>>>>>> 700Kg >> 6860N

D >>>>>>>> 600Kg >> 5880N

From the above calculations we can see that satellite C has the greatest gravitational pull.

Answers

Answer:

Option B. 176g/mol

Explanation:

We'll begin by writing the chemical formula for hexasodium difluoride. This is given below:

Hexasodium means 6 sodium atom

Difluoride means 2 fluorine atom.

Therefore, the formula for hexasodium difluoride is Na6F2.

The relative formula mass of a compound is obtained by simply adding the atomic masses of the elements present in the compound.

Thus, the relative formula mass of hexasodium difluoride, Na6F2 can be obtained as follow:

Molar mass of Na = 23g/mol

Molar mass of F = 19g/mol

Relative formula mass Na6F2 = (23x6) + (19x2)

= 138 + 38

= 176g/mol

Therefore, the relative formula mass of hexasodium difluoride, Na6F2 is 176g/mol
