How is Carbon obtained and how is it separated from other substances nearby?
Answers
Carbon is a naturally occurring element that can be obtained from various sources, both organic and inorganic. It is separated from other substances by Filtration, Distillation, and Chemical Reactions.
Carbon is the fourth-most abundant element in the universe and is a key component of all known life forms. Here are some common methods for obtaining and separating carbon from other substances:
Organic Sources: Carbon is a fundamental element in organic compounds, which are compounds containing carbon atoms bonded to hydrogen and other elements. Organic sources of carbon include:
Fossil Fuels: Coal, oil, and natural gas are rich in carbon. Carbon can be obtained from these sources through processes like combustion, pyrolysis, or gasification.
Biomass: Plant and animal matter, such as wood, leaves, and agricultural residues, contain carbon. Carbon can be extracted from biomass through processes like carbonization or fermentation.
Inorganic Sources: Carbon can also be obtained from various inorganic sources:
Carbonates: Minerals like limestone (calcium carbonate) and dolomite contain carbon in the form of carbonate ions. Carbonates can be thermally decomposed to release carbon dioxide gas, which can then be captured and processed.
Graphite and Diamond: These are naturally occurring forms of carbon. Graphite can be obtained from certain rocks and is used in various industrial applications. Diamonds, although much rarer, are another crystalline form of carbon.
Separation from Other Substances:
Filtration: If carbon is present in a solid mixture, it can be separated using filtration. A porous material (filter paper or a sieve) is used to separate solid carbon particles from other substances based on particle size.
Distillation: If carbon is mixed with liquids that have different boiling points, distillation can be used. The mixture is heated, and the component with the lower boiling point (liquid) vaporizes first, while carbon remains in the original container.
Chemical Reactions: Carbon can be separated from other substances through chemical reactions. For example, carbonates can be treated with acid to produce carbon dioxide gas, leaving behind other components.

Answer:
Carbon products are obtained by heating coal (to give coke), natural gas (to give blacks), or carbonaceous material of vegetable or animal origin, such as wood or bone (to give charcoal), at elevated temperatures in the presence of insufficient oxygen to allow combustion.

Answer : The volume of a diamond is,
Explanation : Given,
Density of a diamond = 3.52 g/ml
Mass of a diamond = 15.1 g
Formula used :
Now put all the given values in this formula, we get the volume of a diamond.
Conversion used :
Therefore, the volume of a diamond is,
Density of a Material
The density of a material is defined as the mass per unit volume
it formula is given as
For the given exercise the correct answer is 4.28 cm^3
Formula for Density
Density = Mass/Volume
and the unit is g/cm^3
Explanation:
Given data
Mass = 15.1 g
Density = 3.52 g/ml
Volume = ????
Hence the Volume is expressed as
Volume = 15.1 /3.52
Volume = 4.28 cm^3
therefore the Volume is 4.29 cm^3

Substance A is mixed with water and donates 0.4% of its H⁺ ions, therefore given substance is a weak acid & show poor conduction of electric current.
What are acids?
According to the Arrhenius theory of acids and bases, acids are those species which gives H⁺ ion to the solution.
In the question it is given that, substance A is mixed with water and it donates H⁺ ion, from this it is clear that given substance is acid. It is also mention that it donates only 0.4% of its H⁺ ion means partial dissociation is observed, so we conclude that this acid is weak in nature. And due to weak dissociation and less number of available H⁺ ion it did not conduct electricity effectively.
Hence, option (D) is correct i.e. it is weak acid and a poor conductor of electric current.
