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

EFFECT OF THE SYMBIOTIC NITROGEN FIXATION ON SOYBEAN INTRODUCTION Legume plants receive nitrogen from Rhizobium which makes them possible to grow in nitrogen poor soil. In return‚ legume plants supply Rhizobium with carbohydrate‚ which is energy. This process is called nitrogen fixation‚ also known as the symbiosis of legume and Rizobium. However‚ it would be inefficient for plants in nitrogen rich soil to transfer their energy to Rhizobium in exchange of nitrogen when sufficient amount of

endangered by the rise in temperatures and carbon levels. It was then that Carla‚ a carbon atom was born at the Sahara desert. At night‚ Carla and her friends went outside to watch the stars peacefully. It had never occurred to them that the night would bring a sudden kidnap. All of Carla’s friends and Carla were attached to two oxygen atoms. Unfortunately‚ Carla fainted during the kidnap so when she woke up‚ she took the surprise of no longer being carbon but carbon dioxide. Carla then turned around and
