Problem 1: In one molecule of the compound, determine how many atoms of every element are present for each one of these chemical formulas. HCN – hydrogen cyanide –It’s a toxic gas C18H21NO3 –codeine, a painkilling drug Ca10(PO4)6(OH)2 –Hydroxyapatite, that is present in the enam...
To determine nutrient concentration, the samples were digested in a microwave with 65% H NO3 and H2O2 (Bock 1972). The solutions were then analyzed using an Agilent 5800 ICP optical emission spectrometer. 1 3Vol.: (0123456789) 1 012 Subsequently, the QSM data were combined with the ...
Non-conductive materials are preliminarily coated with gold, which prevents static charge on the surface. The microscope includes an electrical gun, magnification unit, image generator, condensation and objective lenses, electron collector, and vacuum system. Samples of great value can be observed ...
