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.

Answer:

Liquid has the following properties -

- Liquids are almost incompressible due to the fact that molecules do not have a lot of space between them so they can not be compressed.

- Liquids have a fixed volume but shape varies according to the container it is placed in. It changes the shape even the volume is the same.

- Liquids flow from higher to lower levels.

- Liquids have their boiling points above room temperature, under normal conditions.

Measure the volume of a liquid sample-

The volume of the liquid can find out by dividing the mass of the liquid by the density of the liquid. D = m/v. The density of water is 1 gram/cubic centimeter.

Now, the problem provides you with a mass of ethane,

, and asks for the volume of carbon dioxide,

, formed by the reaction at STP, Standard Temperature and Pressure.

As you know, STP conditions are defined as a temperature of

C

and a pressure of

100 kPa

. Under these specific conditions, one mole of any ideal gas occupies exactly

22.7 L

- this is known as the molar volume of a gas at STP.

So, what this means is that if you know how many moles of carbon dioxide are produced by the reaction, you can use the molar volume of the gas to find the requested volume.

Use the molar mass of ethane to determine how many moles you'd get in that

Now, notice that you have a

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.
