level) The Significance of the noble gas structure in covalent bonding: Atoms that bond covalently produce outer electronic structures that are similar to those of the noble gases‚ i.e.‚ 8 electrons in the outer shell (2.8.8. as in argon and same as helium 2.) Bonding in chlorine Bonding in methane Bonding in oxygen Covalent Bonding Bonding in ammonia‚ NH3 Bonding in carbon dioxide‚ CO2 Carbon has 4 unpaired electrons and so can form 4 covalent bonds.

chromatography was used to analyze the samples. In gas chromatography‚ it puts the solution into two separate phases‚ the mobile (non-polar) and the stationary (polar) phase. The mobile phase is where the solution is carried by an inert gas‚ in this case helium‚ through a column that is heated. For gas chromatography‚ the 3 tubes of solution that we received were individually tested to determine its composition. Next‚ we created a solution of tube A mixed with acetone and tested it through gas chromatography
