Answer:
C₇H₁₁N
Explanation:
To find the chemical formula, first, let's evaluate the given conditions.
1.Is a primary amine:
This means that the amine is connected to a carbon, like NH₂-R
2.The degree of unsaturation of the five-membered carbon ring is equal to three:
One of the degrees of unsaturation is for the five-membered carbon ring, the other two are for pi-bonds. This means that the five-membered carbon ring has 2 pi-bonds inside.
3.There are seven carbon atoms:
Five of these seven carbons are for the carbon ring and the other two are bonded to the primary amine.
From all of the above, we have that the chemical formula is:
C₅H₅-C₂H₄-NH₂ = C₇H₁₁N
I hope it helps you!

Compounds of carbon and hydrogen
Explanation;
An organic compound is any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
The primary difference between organic compounds and inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not contain carbon. Additionally, nearly all organic compounds contain carbon-hydrogen or C-H bonds.
Organic compounds includes nucleic acids, fats, sugars, proteins, enzymes and hydrocarbon fuels. All organic molecules contain carbon, nearly all contain hydrogen, and many also contain oxygen.

The elements according to the decreasing atomic radius are arranged as-
K, Ca, Sc, Ga, Ge, As, Br, Kr
An atomic radius is half the distance between adjacent atoms of the same element in a molecule. It is a measure of the size of the element’s atoms, which is typically the mean distance from the nucleus centre to the boundary of its surrounding shells of the electrons.
An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. The atomic radius decreases on moving from left to right across a period.
Thus the elements according to the decreasing atomic radius are arranged as -
K, Ca, Sc, Ga, Ge, As, Br, Kr

Answer: The for the reaction is -1052.8 kJ.
Explanation:
Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.
According to this law, the chemical equation is treated as ordinary algebraic expressions and can be added or subtracted to yield the required equation. This means that the enthalpy change of the overall reaction is equal to the sum of the enthalpy changes of the intermediate reactions.
The given chemical reaction follows:
The intermediate balanced chemical reaction are:
(1)
(2)
The expression for enthalpy of the reaction follows:
Putting values in above equation, we get:
Hence, the for the reaction is -1052.8 kJ.

Answer:
1. Co ( s ) - metallic bonding
2. CoCl₂ ( s ) - ionic bonding
3. CCl₄ ( l ) - covalent bonding
Explanation:
Metallic bonding -
It is the type of bonding present between the atoms of the metals , via the electrostatic interaction between the metal and the delocalized electrons , is known as metallic bonding .
For example ,
Mostly metals show metallic bonding .
Ionic bonding -
It is the type of bonding present between the ions i.e. , the cation and the anion is known as ionic bonding .
For example ,
Mostly ionic compound , like salts show ionic bonding .
Covalent bonding -
It is the type of bonding which is present between shared pair of electrons , is known as covalent bonding .
For example ,
Most of the carbon compounds are capable to show covalent bonding .
Hence , from the question ,
1. Co ( s ) - metallic bonding
2. CoCl₂ ( s ) - ionic bonding
3. CCl₄ ( l ) - covalent bonding
Final answer:
Co(s) forms metallic bonds, CoCl2(s) forms ionic bonds, and CCl4(l) forms covalent bonds.
Explanation:
The type of bonding within each substance can be identified by understanding the nature of the substances.
- Co(s): Co (solid) denotes a metal, and metals typically form metallic bonds.
- CoCl2(s): CoCl2 is a compound formed between a metal (Co) and a nonmetal (Cl), making it an ionic compound.
- CCl4(l): CCl4 is a molecular compound composed of carbon and chlorine atoms, so it forms covalent bonds.
