through a buildup of greenhouse gases – primarily carbon dioxide‚ methane‚ and nitrous oxide. this is what the carbon footprints calls for CARBON FOOTPRINTS A carbon footprint is a measure of the impact our activities have on the environment‚ and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity‚ heating and transportation etc. The carbon footprint is a measurement of all greenhouse gases

Carbon Dioxide is a colorless‚ odorless gas that occurs in small quantities in the earth’s atmosphere naturally. The earth’s ocean‚ soil‚ plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a ’linear molecule’. Carbon dioxide is commonly found as a gas and is never a liquid. It sublimes to

Unit 4: Carbon Nanostructures Carbon Structures: • Carbon contains six electrons with electronic structure: (1s2)‚ (2s)‚ (2px)‚ (2py)‚ (2pz). Outer s orbital together with three p orbitals form the chemical bonds of carbon with other atoms. • Conventionally‚ solid carbon has two main structures called allotropic forms: diamond and graphite: - Diamond is tetrahedrally bonded through sp3 hybrid bonds that form a 3D network. - Graphite has a layered structure with each layer called graphene formed
