Explanation:

Chemical Bonding refers to the formation of a chemical bond between two or more atoms, molecules, or ions to give rise to a chemical compound.

The subatomic particles that participate are electrons.

Answer:

0.25 moles of COCl₂ are been produced

The element that is oxidized is C, it changed the oxidation state from +2 in CO to +4 in phosgene.

Explanation:

Equilibrium reaction:

Cl₂(g)  +  CO(g)  ⇄  COCl₂(g)

Let's convert the mass of CO to moles:

7g . 1mol /28g = 0.25 moles

As ratio is 1:1, we can say that 0.25 moles of COCl₂ are been produced.

1 mol of chlorine reacts to 1 mol of carbon monoxide in order to produce 1 mol of phosgene.

Chlorine is been reduced:

Cl₂  +  2e⁻  ⇄  2Cl⁻

Change the oxidation state, from 0 (ground state) to -1. Oxidation state decreased.

Carbon is been oxidized.

In CO, carbon has +2 as oxidation state. In phosgene the oxidation state is +4. This oxidation state was increased, that's why it has oxidized.

The element that is oxidized is carbon whose oxidation number was increased from +2 to +4.

The equation of the reaction is;

Cl2(g) + CO(g) ⇄ COCl2(g)

We have been told that the chlorine gas is the reactant in excess hence the carbon monoxide is the limiting reactant.

Number of moles of  CO = 7.0 g/28 g/mol = 0.25 moles

Since the reaction is 1:1, 0.25 moles of COCl2 is produced.

The element that is oxidized is carbon whose oxidation number was increased from +2 to +4.

Answer: Enthalpy is the heat content of a system. The enthalpy change of a reaction is equivalent to the amount of energy lost or gained during the reaction. A reaction is favoured if the enthalpy of the system decreases over the reaction. Entropy refers to the measure of the level of disorder in a thermodynamic system.

The result of the atomic theory was that chemists began to better understand the properties of matter. Therefore, option (D) is correct.

The atomic theory, proposed by John Dalton in the early 19th century, postulated that matter is composed of indivisible particles called atoms. This theory revolutionized the field of chemistry by providing a framework to understand the behavior and interactions of different substances.

By recognizing that matter is composed of discrete atoms with specific properties, chemists were able to explain phenomena such as chemical reactions, the conservation of mass, and the formation of compounds. The atomic theory laid the foundation for modern chemistry, leading to advancements in understanding the structure of atoms, the development of the periodic table, and the ability to manipulate and engineer materials at the atomic level.

Explanation

all are compounds

Yes, as all of these compounds are covalent since they are not conductive. Therefore, the correct option is option D.

A chemical compound is a material made of several similar molecules (as well as molecular entities) joined by chemical bonds and comprising atoms from various chemical elements.

Chemical reactions, which may entail interactions with other molecules, can change a compound into a distinct substance. Atomic bonds may be shattered or new ones created during this process. Yes, as all of these compounds are covalent since they are not conductive.

Therefore, the correct option is option D.

Explanation: Metals are solid at room temp and also are shiny and can be flattened or broken into pieces when hammered and some metals are high and low conductors of electricity.

Metals have a characteristic property of conduction and malleability  and thus  sample 1 is metallic.

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

Answer:

chromosomes is responsible

The reproduction is defined as a process which involves the production of offspring. The genetic instructions are stored in chromosome. The correct option is C.

A chromosome is defined as the DNA molecule which consists of all the genetic material of an organism. It is found to be present in the nucleus of each cell. The DNA inside the chromosome is tightly coiled around special proteins called histones.

All living organisms are composed of chromosomes. Humans have 23 pairs of chromosomes. 22 pairs of these chromosomes are called autosomes. These are same in both males and females. The 23rd pair of chromosomes are called allosomes and they differ between sexes.

The males have one 'X' and 'Y' chromosome, while females have two copies of the 'X' chromosome. The important function of genetic material is to store information needed by the cell to make proteins.

Thus the correct option is C.
