It’s made from Polyvinyl Chloride (PVC). This material was made in 1872 by German chemist Eugen Baumann on accident. Polyvinyl Chloride is made with Chlorine (Cl) and ethylene. When these two are combined ( at extremely high temperatures) they create vinyl chloride monomer. The vinyl chloride monomer can then be polymerized to make polyvinyl chloride. Polyvinyl Chloride is then turned into what we call “synthetic leather”

formulas are written as the smallest whole number ratios of one atom to another‚ whereas molecular shows actual number (sometimes they can be the same as empirical). Common Name Molecular Formula Empirical Formula Hydrogen peroxide H2 O 2 HO Ethylene C 2 H4 CH2 Glucose C6H12O6 CH2O Water H2 O H2 O Steps for Finding Empirical Formula from Mass Percent Values 1. Use the % composition as if it were in grams...like it was a 100 gram sample. 2. Convert from grams to # of mol of each element

any surgical instruments that enter sterile tissue require sterilization before each use. There are different types of sterilization methods; the most reliable technique is using steam under pressure or hot air. Other sterilization methods include ethylene oxide a chemical agent‚ filtration‚ and ionizing radiation. It is important to maintain a sterile field; medical staff can use any amount of medical tools in any procedure. If the infected patient touches a sterile instrument or surface‚ that area
