Which of the following has the highest percentage of carbon?

Anthracite
The correct answer is ​Anthracite. Anthracite is the name of the best variety of coal. The amount of carbon in it ranges from 94 to 98 percent.

What compound contains the most carbon?

There are more carbon compounds than for any other element except hydrogen. The majority of these molecules are organic carbon compounds (e.g., benzene, sucrose), although a large number of inorganic carbon compounds also exist (e.g., carbon dioxide).

What form of carbon has the highest density?

Diamond
Among the following options, Diamond has the highest density. It has density, ranging from 3150 to 3530 kilograms per cubic metre. The density, of a substance, is its mass per unit volume. Diamond is an allotrope of carbon.

Is the coal with the highest percentage of carbon?

Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite.

Which of the coal has highest percentage of carbon?

Anthracite is the type of coal which has the highest percentage of carbon.

Why are the compounds of carbon found to be much more?

Carbon forms numerous compounds because of the following reasons: Catenation – Two carbon atoms readily form covalent bonds, and this bond is more stable than the bonds formed by the other elements. Carbon atoms have varying bond order and hybridisation. That is, they can form double or triple bonds.

Why carbon is a component of most compounds?

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. They can even join “head-to-tail” to make rings of carbon atoms.

Which has the highest density?

Detailed Solution

• Gold has the highest density among the given elements.
• Density of Gold= 19.32 g/cc.
• The density, of a substance, is its mass per unit volume.
• Osmium is the densest element in the periodic table.
• Density of osmium= 22.6 g/cc.

Which of the following materials has the highest density?

The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.

What is the total percentage of carbon present in the human body?

18.5 percent
By mass, about 96 percent of our bodies are made of four key elements: oxygen (65 percent), carbon (18.5 percent), hydrogen (9.5 percent) and nitrogen (3.3 percent).

Why does carbon form a large number of compounds?

Tetravalency: As carbon has 4 electrons in its valence shell and hence can share these electrons with other elements to form large numbers of compounds. It can share its 4 electrons with different atoms or molecules thus generating enormous compounds.

How do you calculate the percentage of carbon in CO2?

For carbon: 1 mass \% C = (mass of 1 mol of carbon/mass of 1 mol of CO2) x 100 2 mass \% C = (12.01 g / 44.01 g) x 100 3 mass \% C = 27.29 \%

How do you calculate the percent mass of carbon in grams?

For carbon: 1 mass \% C = (mass of 1 mol of carbon/mass of 1 mol of CO 2 ) x 100 2 mass \% C = (12.01 g / 44.01 g) x 100 3 mass \% C = 27.29 \%

What is the mass percent composition of a compound?

Percent composition indicates the relative amounts of each element in a compound. For each element, the mass percent formula is: The units of mass are typically grams. Mass percent is also known as percent by weight or w/w\%. The molar mass is the sum of the masses of all the atoms in one mole of the compound.

What is the mass percent of oxygen in CO2 in grams?

mass \% O = (mass of 1 mol of oxygen/mass of 1 mol of CO 2) x 100; mass \% O = (32.00 g / 44.01 g) x 100; mass \% O = 72.71 \%
