Outline the typical structure of a carbon-zinc battery.

Answers

Answer 1

Answer:

Answer: A carbon-zinc battery, often referred to as a standard zinc-carbon battery or just zinc-carbon battery, is a type of primary cell that has been popular for many years due to its simplicity and low cost. Here's a basic outline of the typical structure of a carbon-zinc battery:

Explanation:

Outer Casing (Container):

Typically made of zinc, which also serves as the anode of the battery.

The casing can be cylindrical for standard AA, AAA, C, D cells, or can be rectangular for 9V batteries and other shapes.

Anode (Zinc Container):

The zinc container itself acts as the anode.

When the battery is discharged, the zinc anode oxidizes to form zinc chloride.

Cathode:

Consists of a mix of carbon (often in the form of graphite) and manganese dioxide (MnO₂).

The central carbon rod, typically referred to as the "current collector", is surrounded by the manganese dioxide mixture.

The carbon rod helps channel electrons from the cathode to the external circuit.

Electrolyte:

A paste made up of ammonium chloride (NH₄Cl) or zinc chloride (ZnCl₂) in water.

This paste facilitates the flow of ions inside the battery, completing the internal circuit.

Separator:

Positioned between the anode and the cathode, it prevents them from directly contacting each other, which would result in a short circuit.

It allows the movement of ions and thereby plays an essential role in the battery's electrochemical process.

Cap and Seal:

The top cap is usually made of brass or another conductive material and serves as the battery's positive terminal.

A seal is used to ensure the electrolyte and other components are kept inside, and to prevent external contaminants from entering the battery.

This battery type, while inexpensive, tends to have a shorter life and lower energy density compared to other primary cell types like alkaline batteries. Furthermore, carbon-zinc batteries are more prone to leakage than their alkaline counterparts.

Answer 2

Answer:

Final answer:

A carbon-zinc battery consists of three main parts: a zinc anode which undergoes oxidation, a carbon cathode which aids reduction, and an electrolyte of ammonium or zinc chloride which transfers ions.

Explanation:

A typical carbon-zinc battery, also known as a Leclanché cell, consists mainly of three components: a zinc anode (the negative terminal), a carbon rod as the cathode (the positive terminal), and an electrolyte composed of ammonium chloride or zinc chloride.

The zinc anode is the zinc can that makes up the body of the battery. When the battery is in use, oxidation occurs at the anode, with zinc losing electrons to form zinc ions.

The carbon rod, which is usually surrounded by a mixture of manganese dioxide and carbon black, acts as the cathode. It facilitates the reduction reaction when the battery is in use.

The electrolyte, typically a paste of ammonium or zinc chloride, serves as a means for the transfer of ions between the anode and cathode.

Therefore, the traditional structure of a carbon-zinc battery consists of a zinc can acting as the anode, a carbon cathode surrounded by a mixture of manganese dioxide and carbon black, and an electrolyte paste in between.

Which of the following species has the greatestnumber of electrons?
1. Cl1−
2. Co4+
3. Fe2+
4. V
5. Sc2−

Answers

Answer: Option (3) is the correct answer.

Explanation:

When there is a negative charge on an atom then we add the charge with the number of electrons. Whereas when there is a positive charge on an atom then we subtract the charge from the number of electrons.

Atomic number of chlorine is 17. So, number of electrons present in $Cl^(-)$ is 17 + 1 = 18 electrons.

Atomic number of cobalt is 27. So, number of electrons present in $Co^(4+)$ is 27 - 4 = 23 electrons.

Atomic number of iron is 26. So, number of electrons present in $Fe^(2+)$ is 26 - 2 = 24 electrons.

Atomic number of vanadium is 23. So, number of electrons present in V is 23 electrons.

Atomic number of scandium is 21. So, number of electrons present in $Sc^(2-)$ is 21 + 2 = 23 electrons.

Thus, we can conclude that out of the given species, $Fe^(2+)$ has the greatest number of electrons.

Among the given species, $\boxed{3.{\text{ F}}{{\text{e}}^(2 + )}}$ has the greatest number of electrons.

Further Explanation:

The arrangement of electrons in various shells and sub-shells of an atom is called electronic distribution. The electron filling is done by keeping following rules and principles in mind:

(i). Aufbau principle

According to this, electron filling takes place in orbitals in the increasing order of their respective energies. The energy order of orbitals is as follows:

$1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7p$

(ii) Hund’s rule

No electron will b epaired until each orbital is singly occupied.

(iii) Pauli’s exclusion principle

It states that two electrons can never have all the four quantum numbers same. The value of spin quantum number for both electrons must b edifferent.

1. According to the periodic table, the atomic number of Cl is 17 so its electronic configuration is $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^7}4{s^2}$ . It gains an electron to form ${\text{C}}{{\text{o}}^(4 + )}$ ion and its configuration becomes $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^5}$ . So it has a total of 18 electrons.

2. According to the periodic table, the atomic number of Co is 27 so its electronic configuration is $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^7}4{s^2}$ . It loses four electrons, two 4s electrons and two 3d electrons to form ion and its configuration becomes $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^5}$ . So it has a total of 23 electrons.

3. According to the periodic table, the atomic number of Fe is 26 so its electronic configuration is $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^6}4{s^2}$ . It loses two 4s electrons to form ${\text{F}}{{\text{e}}^(2 + )}$ ion and its configuration becomes $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^6}$ . So it has a total of 24 electrons.

4. According to the periodic table, the atomic number of V is 23 so its electronic configuration is $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^3}4{s^2}$ . So it has a total of 23 electrons.

5. According to the periodic table, the atomic number of Sc is 21 so its electronic configuration is $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^1}4{s^2}$ . It gains two electrons to form ${\text{S}}{{\text{c}}^(2 - )}$ ion and its configuration becomes $1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}3{d^3}4{s^2}$ . So it has a total of 23 electrons.

Therefore, the maximum number of electrons is present in ${\text{F}}{{\text{e}}^(2 + )}$ (24).

Answers

To solve this we use the equation,

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

65 x V1 = 2 x 200 L

V1 = 6.15 L

Explanation:

Which sample of matter is a mixture?
(1) Br2(ℓ) (3) KBr(s)
(2) K(s) (4) KBr(aq)

Answers

Answer:

KBr (aq) is a mixture.

Explanation:

Mixture is defined as the combination of two non reacting species. Let's discuss each option one by one.

a) Br₂(l):

This Bromine is not a mixture because the bracket specifying the state of Br₂ is liquid. Hence, as bromine is a liquid at room temperature, so this compound is purely Br₂.

b) KBr (s):

KBr is also present in pure form because in bracket solid is written.

c) K (s):

Potassium is also present in pure form as the bracket is specifying solid, as KBr is solid at room temperature.

d) KBr (aq):

This is a mixture of KBr and water. Because KBr being an electrolyte when dissolved in water it is hydrated as follow,

KBr (s) -----water------> K⁺ (aq) + Br⁻ (aq)

$\boxed{\left( {\text{4}} \right){\text{ KBr}}\left( {aq} \right)}$ is a mixture.

Further explanation:

Mixture:

It is formed by the physical combination of two or more different substances. Mixtures do not have any fixed formula and their composition is also variable. There is retention in the properties of constituents even after the formation of mixtures.

(1) ${\text{B}}{{\text{r}}_2}\left( l \right)$

Bromine is present in liquid in its pure state. The “l” written in the parenthesis after denotes its physical state which is the same as that of its pure form. So it is not a mixture.

(2) K (s)

Potassium is present in solid in its pure form. The “s” written in the parenthesis after K describes its physical state which is the same as that of its pure form. So it is not a mixture.

(3) KBr (s)

It is an ionic salt which is solid in nature. The “s” written in the parenthesis after KBr denotes its physical state which is the same as that of its pure form. So it is not a mixture.

(4) KBr (aq)

The “aq” written in the parenthesis after KBr indicates that it is present in the aqueous phase. This means it is formed by the combination of KBr and water so it is a mixture.
