What Is The Combined State Of Carbon?

in combined state, carbon occurs as coal. or it can be diamond,graphite or fullerenes.

What is the state of carbon?

Carbon atoms are arranged in a regular pattern, meaning carbon is solid at room temperature.

What is combined state?

Answer: combined state:- A compound consists of at least two dissimilar elements combined in a definite ratio.

Why do carbon exist mostly in combined state?

Carbon is an element that can form many different compounds, as each carbon atom can form 4 chemical bonds with other atoms and because the carbon atom is just the right size to fit in comfortably as parts of very large molecules.

What is the Free state of carbon?

Occurence of carbon : In free state – diamond, graphite, in impure form as coal. In combind state : CO₂ in atmosphere, hydro-carbon as natural gas, petroleum, cellulose in wood and limestone CaCO₃.

How carbon occurs in the Free state and in the combined state?

Q2) State how carbon occurs in the free state and in the combined state. Solution: It occurs as diamond, graphite in impure form as coal, in the free state. It occurs as carbon dioxide in the atmosphere, hydro-carbon as natural gas, petroleum, cellulose in wood and limestone in combined states.

What are the 3 types of carbon?

The three most popular forms or we can say allotropes of carbon are graphite, diamond and fullerene (also known as Buckyball). These three allotropes are found in the form of crystals instead of molecules.

Which of the following occurs combined state?

2. Combined State. The elements which are reactive and have a tendency to combine with oxygen or air, moisture, carbon dioxide, and non-metals like carbon, nitrogen, sulphur, phosphorus, arsenic, halogen, etc., occur in the combined state.

What is native state and combined state?

The term native state refers to metals which are found chemically uncombined in nature. A compound consists of at least two dissimilar elements combined in a definite ratio. This is combined state.

What is combined state of metal?

The metal found in nature occur in the free or combined state it is generally known as pure metals. A native metal is a metal found in metallic state naturally.

Is Coke a free state of carbon?

– Carbon exists in free state as well as combined state. – Allotropes of carbon such as diamond, graphite, and coal occur in free state.- Coke is nearly pure carbon which is formed by heating coal in vacuum. Therefore, the correct answer is (D) Petrol.

What are allotropes of carbon?

When an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite.

Is petrol free state of carbon?

Petrol is not the free state of carbon.
It is present in periodic table in 6th position.

What is the difference between Free state and combined state?

General Science
Free State means that is found as JUST the element. For instance, you can find elemental hydrogen (just H) in volcanoes, the sun, etc. A compound consists of at least two dissimilar elements combined in a definite ratio.

What is the oxidation state of carbon?

So unlike metals, which are almost always in a positive oxidation state, the oxidation state of carbon can vary widely, from -4 (in CH4) to +4 (such as in CO2). Here are some examples. (Don’t forget that this is called a “formalism” for a reason. The charge on the carbon is not really +4 or –4.

Is carbon found in Free state in nature?

In nature, carbon occurs in free state as well as in combined state. In free state it is found as coal, diamond, graphite and fullerenes.

What do you mean by Allotropy?

allotropy, the existence of a chemical element in two or more forms, which may differ in the arrangement of atoms in crystalline solids or in the occurrence of molecules that contain different numbers of atoms.

What are the 4 forms of carbon?

The atoms of carbon can bond together in diverse ways, resulting in various allotropes of carbon. Well-known allotropes include graphite, diamond, amorphous carbon and fullerenes. The physical properties of carbon vary widely with the allotropic form.

What is the English name of carbon?

The name of carbon comes from Latin carbo, meaning charcoal. In many foreign languages the words for carbon, coal and charcoal are synonyms.

What are the 2 types of carbon?

Diamond and GraphiteDiamond and graphite are two allotropes of carbon — pure forms of the same element that differ in structure.

Is iron found in combined state?

Iron is found in the free state in nature.
