SLS functions in cleaning product as a surfactant, wetting surfaces, emulsifying or solubilizing oils, and suspending soil so that they can be rinsed away. This ingredient contributes foaming properties to cleaning products. SLS is safe for use in cleaning products.

Sodium lauryl sulfate and ammonium lauryl sulfate are surfactants that help with the mixing of oil and water. As such, they can clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away or suspend poorly soluble ingredients in water.

The U.S. Food and Drug Administration (FDA) includes sodium lauryl sulfate on its list of multipurpose additives allowed to be directly added to food. Sodium lauryl sulfate and ammonium lauryl sulfate are also approved indirect food additives. For example, both ingredients are permitted to be used as components of coatings.

The safety of sodium lauryl sulfate and ammonium lauryl sulfate has been assessed by the Cosmetic Ingredient Review  (CIR) Expert Panel on two separate occasions (1983 and 2002), concluding each time that the data showed these ingredients were safe in formulations designed for brief, discontinuous use, followed by thorough rinsing from the surface of the skin. In products intended for prolonged contact with skin, concentrations should not exceed 1%.  

Sodium lauryl sulfate and ammonium lauryl sulfate may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union.

Answer:

4.37 g of barium sulphate

Explanation:

The reaction equation is;

3BaCl2(aq) + Fe2(SO4)3(aq) ---->3 BaSO4(s) + 2FeCl3(aq)

From the question, the number of moles of both barium chloride and FeSO4 = 125/1000 L × 0.150 M = 0.01875 moles

To find the limiting reactant;

3 moles of barium chloride yields 3 moles of barium sulphate

0.01875 moles of barium chloride yields 3 × 0.01875 moles/3 = 0.01875 moles of barium sulphate

1 mole of iron III sulphate yields 3 moles of barium sulphate

0.01875 molesof iron III sulphate yields 0.01875 moles ×3/1 = 0.05625 moles of barium sulphate

Hence,barium chloride is the limiting reactant

Amount of barium sulphate produced = 0.01875 moles × 233 g/mol = 4.37 g of barium sulphate

Option A. ⁰₋₁β

Explanation:

Let the unknown be ʸₓA

Thus, the equation given becomes:

⁹⁸₄₃Tc —> ⁹⁸₄₄Ru + ʸₓA

Next, we shall determine the value of x, y and A in order to obtain the answer to the question. This can be obtained as follow:

Answer: The statement diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated, is false.

Explanation:

When particles or atoms of a substance are able to move rapidly from one place to another then it is called diffusion.

During diffusion, particles tend to move apart from each other.

For example, spreading of dye molecules into water.

Thus, we can conclude that the statement diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated, is false.

Answer: Among the listed substances [tex]XeCl_{4}[/tex] is the molecular compound.

Explanation:

A chemical compound formed by the chemical combination of two or more non-metals is called a molecular compound or covalent compound.

For example, Xe and Cl are non-metals. The compound formed by them is [tex]XeCl_{4}[/tex] which is a molecular compound.

A molecular compound is formed by sharing of atoms between the combining atoms.

Whereas NaF, [tex]MnCl_{2}[/tex] and CaO are all ionic compounds as they are formed by chemical combination of a metal and a non-metal.

Thus, we can conclude that among the listed substances [tex]XeCl_{4}[/tex] is the molecular compound.

Answer:

1.5057×10^22 atom

Explanation:

As we

1 mole of argon = 40 g of argon

i.e 40 g of argon = 1 mole of argon

1 g of argon = 1/40 mole of argon

1 mole of argon = 6.023×10^23 atom of argon

1/40 mole if argon = 1/40 ×6.023×10^23

= 1.5057×10^22

The number of atoms of Argon in 1 g would be 1.51 × 10²²

To find out the number of atoms of Argon in 1 g of Argon, the number of moles has to be calculated from which the number of atoms can be derived.

The molecular mass of Argon is 40. The number of moles of Argon is calculated as:

Number of moles of Argon = [tex]\frac{Mass of Argon in grams}{Molecular mass of Argon}[/tex]

Substituting molecular mass as 40 and mass in grams as 1. we get:

Number of moles of Argon = [tex]\frac{1}{40}[/tex] = 0.025 mol

Number of atoms in 1 mole of any substance is given by Avogadro's number as 6.022 × 10²³.

Thus, number of atoms of Argon in 0.025 moles would be

= 0.025 × 6.022 × 10²³

= 0.151 × 10²³ or 1.51 × 10²²

Answer:

See explanation

Explanation:

The structure of ethylene is shown in the image attached. The two carbon atoms have a double covalent bond between them.

The two carbon atoms are sp2 hybridized. The bond between them is a covalent bond, there is one pi bond and one sigma bond between the carbon atoms. Between carbon and hydrogen, there are covalent bonds also. The covalent bonds are sigma bonds.

The pi bonds between carbon atoms is weaker than the sigma bonds between the carbon atoms. This is because, the side-by-side overlap the p orbitals in a pi bond is less effective than the end-to-end overlap of a sigma bond.

Elements in the same family have the same number of protons. This  statement is not true about the periodic table. Therefore, option A is correct.

The chemical elements are arranged in rows and columns in the periodic table, sometimes referred to as the periodic table of the elements. It is frequently used in physics, chemistry, and other sciences and is frequently regarded as a symbol of chemistry.

The table can be used by scientists to anticipate chemical reactions, study trends in the periodic properties of certain elements, and speculate on the properties of yet-to-be-discovered elements. The elements are arranged in the contemporary periodic table according to their atomic numbers and periodic characteristics.

The periodic table has changed to represent more than 150 years of chemical and physics research and development.

Answer:

VSEPR theory

Explanation:

The valence shell electron pair repulsion theory was propounded by Gillespie and Nylom (1957).

The entire idea of the VSEPR theory is that the shape of a molecule depends on the electrostatic repulsion between electron pairs surrounding the central atom in a molecule which causes these pairs to be separated as far as possible.

The shapes of many molecules can be accurately predicted based on this model.

Answer:

8.87 × 10³ moles.

Explanation:

To convert number of molecules of sulfur hexafluoride (SF6) to moles (n), we divide by Avogadro's number (6.02 × 10²³)

That is; n = N ÷ nA

According to the question, 5.34 x 10^27 molecules of SF6 was given in this question. Hence, the number of moles it contains is given as:

n = 5.34 x 10^27 ÷ 6.02 × 10²³

n = 5.34/6.02 × 10^ (27-23)

n = 0.887 × 10⁴

n = 8.87 × 10³ moles.

Answer:

84.324  gram
