.Write a short paragraph describing how electronegativity and molecular shape determine the polarity of a molecule. In your paragraph, describe why chemists consider relative electronegativity values and not absolute electronegativity values when determining the polarity of a bond. Also explain how a molecule with polar bonds can be non-polar overall

Answers

Answer 1

Answer:

See explanation

Explanation:

Electro negativity refers to the ability of an atom in a molecule to attract the shared pair of electrons of a bond closer to itself.

In a molecule, the polarity of bonds is determined by the relative electro negativity of the bonding atoms. If the difference in electro negativity between the atoms in a bond is significant, such a bond is polar in nature e.g H-Cl, H-Br, C-F, etc.

However, the occurrence of polar bonds in a molecule alone does not guarantee the polarity of the molecule. The polarity of a molecule also depends on the shape of the molecule since dipole moment is a vector quantity.

A molecule is polar when the resultant dipole moment which is determined by the shape of the molecule is non zero.

For instance, CO2 contains two polar C-O bonds but the molecule is non polar because the two dipole moments cancel out. Also, symmetrical molecules are nonpolar irrespective of the presence of polar bonds in the molecule.

238 U 92 write the following decay sequence.​

Answers

Answer: The given decay sequence is [tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex].

Explanation:

An alpha-particle is a helium atom. Hence, when an alpha decay occurs in [tex]^{238}_{92}U[/tex] then the reaction equation is as follows.

[tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He[/tex]

Now, in sequence the equation for beta decay is as follows.

[tex]^{234}_{90}Th \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex]

Hence, the sequence will be as follows.

[tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex]

Thus, we can conclude that the given decay sequence is [tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex].

4. Assign an oxidation state to the element whose atom is underlined in the following compound: AIH3
O Al: +5
O Al: -5
Ο Ο Ο
Al: -3
O Al: +3

Answers

Answer: The oxidation state of Al in [tex]AlH_{3}[/tex] is +3.

Explanation:

The number attained by an atom or substance due to loss or gain of electrons is called oxidation state.

For example, in [tex]AlH_{3}[/tex] it is known that the oxidation state of hydrogen is -1 as aluminum is a cation so it cannot have an oxidation state as 'minus'.

Whereas hydrogen has the property to act both as a cation and an anion.

Let us assume the oxidation state of Al is x in the compound [tex]AlH_{3}[/tex].

Hence, oxidation state of Al is calculated as follows.

[tex]x + 3(-1) = 0\\x - 3 = 0\\x = +3[/tex]

This means that the oxidation state of Al in [tex]AlH_{3}[/tex] is +3.

Thus, we can conclude that oxidation state of Al in [tex]AlH_{3}[/tex] is +3.

B. n₂=V₂n₁/V₁

What is the final number of moles?

0.08  mol

__________________________________________________________

Explanation:

The ideal gas law is Boyle's law, Charles's law, Gay-Lussac's law, and Avogadro's law combined into one equation. Avogadro's law is V₁/N₁=V₂/N₂, Charles's law is V₁/T₁=V₂/T₂, Gay-Lussac's law is P₁/T₁=P₂/T₂, and Boyle's law is P₁V₁=P₂V₂.

For the balloon problem, B is the correct answer because we are looking for the final moles of gas added. Answer B gives the equation that equals n₂, n₂ means final number of moles. The problem gives us initial volume (500 mL), final volume (1 L), and initial moles amount (0.04 mol). Plug these numbers into the equation, n₂=V₂n₁/V₁, using consistent units. Note that V₁=initial volume, V₂=final volume, n₁=initial moles, and n₂=final moles

What should the student do to balance the equation?

Answers

Answer: The student must add 2 infront of both [tex]H_2O[/tex] and [tex]SO_2[/tex] to make the equation balanced.

Explanation:

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

For the given unbalanced chemical equation:

[tex]2H_2S+3O_2\rightarrow H_2O+SO_2[/tex]

On the reactant side:

Atoms of H = 4

Atoms of S = 2

Atoms of O = 6

On the product side:

Atoms of H = 2

Atoms of S = 1

Atoms of O = 3

To balance the equation, a student must balance the atoms by adding 2 infront of both [tex]H_2O[/tex] and [tex]SO_2[/tex]

For the balanced chemical equation:

[tex]2H_2S+3O_2\rightarrow 2H_2O+2SO_2[/tex]

Consider the reaction 4FeS2 + 11O2 → 2Fe2O3 + 8SO2. If 8 moles of FeS2 react with 15 moles of O2, what is the limiting reactant? (3 points)


Select one:

a. FeS2

b. Fe2O3

c. O2

d. SO2

Answers

If 8 moles of FeS2 react with 15 moles of O2, the limiting reactant is O2.

WHAT IS LIMITING REACTANT:A limiting reactant is reactant that is totally consumed when the chemical reaction is completed.

According to this question, the following reaction was given: 4FeS2 + 11O2 → 2Fe2O3 + 8SO2.

4 moles of FeS₂ reacts with 11 moles of O₂

This means, 8 moles of FeS₂ will react with (8 × 11/2) = 22 moles of O₂

15 moles of O₂ is available. In comparison with 22 moles, O₂ is in short supply .

Therefore, If 8 moles of FeS2 react with 15 moles of O2, O₂ is the limiting reagent.

Which of the following statements regarding carbon is false? Group of answer choices Carbon has the capacity to form single and double bonds. Carbon has the ability to bond with up to six other atoms. Carbon has a tendency to form covalent bonds. Carbon has the ability to bond together to form extensive branched or unbranched "carbon skeletons."

Answers

Answer: The statement, carbon has the ability to bond with up to six other atoms is false.

Explanation:

Carbon is a group 14 element and it is a non-metal. The atomic number of carbon is 6 and its electronic distribution is 2, 4.

This means that there are 4 valence electrons present in it. Also, in order to attain stability a carbon atom forms only covalent bonds, that is, it shares its valence electrons with its own atoms or atoms of other elements.

Carbon has the capacity to form single and double bonds.

As valency of carbon is four so it can only combine to 4 other atoms vis single bond and it cannot bond with up to six other atoms.

Carbon shows the property of catenation, that is, it forms covalent bonds with its own atoms in a large number. So, carbon has the ability to bond together to form extensive branched or unbranched "carbon skeletons".

Thus, we can conclude that the statement, carbon has the ability to bond with up to six other atoms is false.
