Answer:

a.HF

b.co

c.oH

d.pcl

e.NH

f.po

g.CN

a) Among HF or HCl the more polar bond is HF. b) Among NO or CO, the more polar bond is CO. c) Among SH or OH, the more polar bond is OH. d) Among PCl or SCl, the more polar bond is PCl. e) Among CH or NH, the more polar bond is NH. f) Among SO or PO, the more polar bond is SO. g) Among CN or NN, the more polar bond is CN.

To determine the more polar bond in each pair, we need to consider the electronegativity difference between the bonded atoms. The greater the electronegativity difference, the more polar the bond. Electronegativity is a measure of an atom's tendency to attract electrons towards itself in a chemical bond.

The electronegativity values (Pauling scale) for the elements involved in the bonds are:

H = 2.20

F = 3.98

Cl = 3.16

N = 3.04

O = 3.44

S = 2.58

P = 2.19

C = 2.55

a. HF or HCl

HF: Electronegativity difference = 3.98 - 2.20 = 1.78

HCl: Electronegativity difference = 3.16 - 2.20 = 0.96

The more polar bond is HF.

b. NO or CO

NO: Electronegativity difference = 3.04 - 2.55 = 0.49

CO: Electronegativity difference = 3.44 - 2.55 = 0.89

The more polar bond is CO.

c. SH or OH

SH: Electronegativity difference = 2.58 - 2.20 = 0.38

OH: Electronegativity difference = 3.44 - 2.20 = 1.24

The more polar bond is OH.

d. PCl or SCl

PCl: Electronegativity difference = 3.16 - 2.19 = 0.97

SCl: Electronegativity difference = 3.16 - 2.58 = 0.58

The more polar bond is PCl.

e. CH or NH

CH: Electronegativity difference = 2.55 - 2.20 = 0.35

NH: Electronegativity difference = 3.04 - 2.55 = 0.49

The more polar bond is NH.

f. SO or PO

SO: Electronegativity difference = 2.58 - 3.44 = -0.86

PO: Electronegativity difference = 2.19 - 3.44 = -1.25

The more polar bond is SO.

g. CN or NN

CN: Electronegativity difference = 3.44 - 2.55 = 0.89

NN: Electronegativity difference = 3.04 - 3.04 = 0

The more polar bond is CN.

Answer:

35.50 atomic mass

Explanation:

1. Multiplicate each isotope mass by its abundance

35 uma x 75% = 26.25 amu

37.01 uma x 25% = 9.2525 amu

2.  Add the values

26.25 +  9.2525  = 35.50 atomic mass

Answer:

1 = 252g, 2 = 2mL, 3 = 1.5mL, 4 = 3g, 5 = 225g, 6 = 0.92g/mL, 7 = 0.75g/mL, 8 = 0.71g/mL, 9 = 1.9mL, 10= 1.11mL, 11 = 76.9g

Answer:

The process that converts a solid mcompound into a gas is sublimation.

E.g- dry ice, solid iodine and ammonium salts

when the above solid are heated, only particles which are found on the surface of the solid gain enough energy and break all forces of attraction and form a gas.

Explanation:

Acrylonitrile  and ethyl acetate can not be separated by simple distillation since they have the same boiling point.

Distillation is a separation technique in chemistry which can be applied only when the substances to be separated have different boiling points. The method relies on the difference between the boiling points of the components of a mixture in order to achieve separation.

Whereby Acrylonitrile and ethyl acetate have the same boiling point: 77.2°C, separation by distillation becomes impossible because the two substances are collected together.

Answer:

Mendeleev’s periodic table is, based on the relation of elements’ properties as dependent on the atomic weight of the element. But the Modern periodic table considers atomic number as the fundamental property that decides the properties of elements.

The modern periodic table does correct the defects of Mendeleev’s periodic table. For example, in Mendeleev’s periodic table, in the element pairs, Argon-potassium, cobalt-nickel, tellurium-iodine and thorium and protactinium, elements with higher atomic mass precede the element with lower atomic weight. However, it is the right places for them but is against Mendeleev’s periodic law.

These elements atomic number shows the reverse order compared to atomic mass. The supposed to be wrong positions in Mendeleev’s table has the right explanation justifying their positions.

We know that the sunscreen preparation contains a 2.7% by mass of Benzyl Salicylate. From this, we will find that they need 1.559 kg of Benzyl Salicylate to make 340 tubes of sunscreen.

The initial data means that if the total mass of sunscreen is M, then the mass of Benzyl Salicylate will be 2.7% of M, or:

(2.7%/100%)*M = 0.027*M

Now, we know that a tube contains 6.0 oz of sunscreen.

Then M = 6.0oz

A tube contains:

0.027*6.0oz = 0.162 oz.

Then in 340 tubes, we will need 340 times 0.162 oz of Benzyl Salicylate, this is:

340* 0.162 oz = 55.08oz

And we want this quantity in kg.

Knowing that:

1oz = 0.028kg

Then 55.08oz is 55.08 times 0.028kg:

55.08*0.028kg = 1.559 kg

So they will need  1.559 kg of Benzyl Salicylate to make 340 tubes of sunscreen.

Answer:

C₂H₄-CH₄-CH₂O-SO₂-Cl₂

Explanation:

The arrangement of gases in increasing order of the number of atoms that make up its molecule, from left to right, is C₂H₄-CH₄-CH₂O-SO₂-Cl₂.

Gas is one of the matters. It's invisible, and its particles are present very far away from each other. The atoms of the gas move randomly, and they are always in motion.

There are iii kinds of matter, solid, liquid, and gas. When there is a modification in temperature when there is a rise in temperature the solid becomes liquid and eventually, the liquid becomes gas.

The arrangement of gases in it increases the order of the number of atoms. So it can be identified by seeing the moles of elements that are shown in the chemical formula of gas.

Thus, the arrangement of gases is C₂H₄-CH₄-CH₂O-SO₂-Cl₂.

Hello,

Elements are a group of the Periodic Table that shares common valence electron structures. They are arranged in order of increasing Atomic Number.

In modern periodic table they are classified into three parts- metals, non-metals and metalloids.

In detail:-

• Metals- Metals are those elements which donate electrons. Ex- Na, K, Rb, Mg, Ca, etc.

• Non-metals- Non-metals are those elements which accept electrons. Ex- N, O, F, Cl, etc .

• Metalloids- Metalloids are those elements which show property of both metals and non-metals. Ex- B, Si, Ge, etc.

Answer:

A bottle that is sealed would have the highest concentration.

Explanation:

When you put a gas into a container, the concentration or the amount of mol inside the bottle would be highly concentrated. If you open the bottle, the CO2 would spread outwards and leave the bottle giving more room between each molecule. The longer you open the bottle, the less concentrated the gas will be.
