Every subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals. This course is designed to expose students to the applications of chemistry in selected important industries. Intended Learning Outcomes: Upon completion of this course students should be able to: • identify the types of polymers and their polymerization mechanisms. • explain the properties of polymers based on their structures. ...In chemistry, 6O2 is six molecules of O2, which equals 12 atoms of oxygen. The “O2” is a molecule of oxygen gas, while the “6” indicates that there are six such molecules. Oxygen is most stable when it is in groups of two atoms, hence O2 is...Chirality. Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions. Figure 4 shows an example of two molecules, chiral ...

Longer distances are often reported in kilometers (1 km = 1000 m = 10 3 m), whereas shorter distances can be reported in centimeters (1 cm = 0.01 m = 10 −2 m) or millimeters (1 mm = 0.001 m = 10 −3 m).Thin layer chromatography (TLC) is an extension of paper chromatography and uses a different stationary phase. Using thin layers of stationary phase for separations is called "thin layer chromatography" (TLC), and is procedurally performed much the same way as paper chromatography. TLC is a common technique in the organic chemistry laboratory ...
