(Relative atomic mass: S=32,0=16)
(A) 0.56 g
B) 5.6 g
(C) 56 g
C) 560g
The mass of oxygen gas contains the same number of moles as 56g of sulphur is 56g
Calculation,
Number of moles of sulphur = given mass/ molar mass of sulphur
Number of moles of sulphur = 56/ 32 moles
Number of moles of sulphur = 1.75 moles
According to question,
Number of moles of sulphur = Number of moles of oxygen(O2)
So, Let mass of oxygen be X.
Number of moles of oxygen = X/16×2 = 1.75 moles
Mass of oxygen (X) = 1.75×16×2 grams
Mass of oxygen (X) = 56 grams
The 6.022×1023 of chemical species like an electrons, molecules atoms, ions etc is called moles

Answer:
C. 56 g
Explanation:
56 g S (1 mol S/ 32 g) = 1.75 mol S
1.75 mol O2 (32 g/ 1 mol O) = 56 g O2
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.
