CONTENT ANALYSIS
CARBON AND ITS COMPOUNDS
INTRODUCTION:
Content analysis is a method for studying documents and communication artifacts, which might be texts of various formats, pictures, audio or video. Social scientists use content analysis to examine patterns in communication in a replicable and systematic manner. Practices and philosophies of content analysis vary between academic disciplines. They all involve systematic reading or observation of texts or artifacts which are assigned labels.
The chapter CARBON AND ITS COMPOUNDS include the introduction to carbon compounds, about their bonding and the nature of carbon. The chemical properties of carbon are also well explained.
Terms:
Carbon compounds, charcoal, lamp black, allotropy, diamond, graphite, fullerene, graphene, refractive index, lustrous, lubricant, hexagons, Bucky balls, carbon nanotubes, isotopes, fossils, carbon dating, carbon monoxide, global warming, green house effect, carbonates, bicarbonates, washing soda, baking soda, valency, catination, hydro carbons, homologous series, unsaturated, alkanes, alkenes, alkynes, double bond, triple bond.
Facts:
The compound containing carbon are much larger in number than those containing other elements.
New compounds of carbon are being discovered everyday.
Carbon is seen both in the elemental state and combined state.
Diamond is the hardest allotrope of carbon.
Diamond is not a good conductor of electricity.
Pure diamonds are colourless, chemically and structurally.
Diamond has high refractive index and high thermal conductivity.
Graphite is the most stable allotropic of carbon.
Graphite is lustrous.
Graphite conduct electricity
Graphite is non volatile.
Graphene are two dimensional sheets of hexagonal rings formed by carbon.
Graphenes are the basic units of the allotropes of carbon.
Carbon dioxide is a colorless gas.
Carbon dioxide doesn’t support combustion.
Carbon dioxide is odorless.
Carbon dioxide is formed as a result of combustion of fuels.
Carbon dioxide is formed when carbon compounds are burnt in air.
Carbon monoxide is formed by the incomplete combustion of carbon in a limited supply air.
Methane has one carbon atom and four hydrogen atoms.
Carbon has four electrons in the outermost shell.
The ability for catenation is very high for carbon atoms.
A carbon atom can combine with four different atoms or groups at the same time.
Concepts:
The charcoal residue left behind when substances undergo combustion is due to the presence of carbon.
The black smoke formed when substances burn is due to the presence of carbon.
In diamond, carbon atom is linked by covalent bonds with four other atoms surrounding it.
Diamond does not conduct electricity due to the absence of free electrons.
Allotropy is the phenomenon by which same element exist in different form.
In graphite, each carbon atom is covalently bonded with three other carbon atoms.
The presence of free electrons makes graphite a good conductor of electricity.
Graphenes are the basic units of the allotropes of carbon.
Isotopes are the atoms of the same element having the same atomic number but different mass numbers.
The solid form of carbon dioxide is used as a refrigerant.
Carbon dioxide, carbon monoxide, carbonates and bicarbonates are carbon compounds obtained from inorganic materials like minerals and salt.
Alkanes are known as saturated hydrocarbons.
Definitions:
The phenomenon by which same element exist in different physical forms is called allotropy.
The atoms of same element having the same atomic number but different mass number are called isotopes.
Compounds containing only carbon and hydrogen are called hydrocarbons.
The hydrocarbons having only single bond between carbon atoms are called alkanes.
Hydrocarbons having a double bond between carbon atoms are called alkenes.
Hydrocarbons having triple bond between carbon atoms are called alkynes.
Equations:
C + O2 → CO2
CH4 + 2O2→CO2 + 2H2O
2C + O2→ 2CO
Na2CO3 + BaCl2→ BaCO3 + 2NaCl
Symbols:
Carbon dioxide → CO2
Carbon monoxide→ CO
Washing soda→ Na2CO3 .10H2O
Baking soda→ NaHCO3
Marble→CaCO3
CONCLUSION:
The chapter, carbon and its compounds deals with the bonding in different carbon compounds. Also it mention different types of carbon compounds like fullerene, diamond, graphite etc. Content analysis helps to mention the important terms, facts etc related to the above mentioned chapter.
