WebUltraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet ( ultraviolet C or UVC, commonly referred to wavelengths between 200 – 280 nm) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions (17). WebAn ion has 12 protons, 14 neutrons, and 10 electrons. The symbol for the ion is. A student performs an experiment to determine the density of a sugar solution. She obtains the following results: 1.11 g/mL, 1.81 g/mL, 1.95 g/mL, 1.75 g/mL. If the actual value for the density of the sugar solution is 1.75 g/mL, is the student accurate or precise ...
