Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4 Valence electrons: 4 Property: Non-metal Abundance: Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon: The Covalent Bond

Research Topic The introduction of a carbon tax in Australia would have implications for economic and environmental sustainability. Obviously in the longer term the aim of the tax is to promote environmental sustainability but in the short term there will be implications for economic sustainability for a range of businesses and households. Using a range of current sources including reports and newspaper articles discuss the short and longer term implications of a carbon tax for the tourism and hospitality

How do you keep carbon dioxide from escaping a carbonated drink when the drink’s container has been opened? When you open a carbonated beverage’s container‚ such as a soda can or bottle‚ you may hear a hissing sound from the opening as you do so. That is the sound of the carbon dioxide gas escaping from the sealed container through the new opening. When this happens‚ the process of the beverage losing its so-called "fizz" has already begun. However‚ there are several solutions to this issue. This

and supporting wildlife. During the process of photosynthesis‚ trees take in carbon dioxide and produce the oxygen we breathe. According to the U.S. Department of Agriculture‚ "One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen. This is enough to meet the annual needs of 18 people." Trees‚ shrubs and turf also filter air by removing dust and absorbing other pollutants like carbon monoxide‚ sulfur dioxide and nitrogen dioxide. After trees intercept unhealthy particles
