When you hear the word "normality," science may not be the first thing that comes to mind. "Normal," to most people, means "ordinary" or "typical," and doesn't seem to have a whole lot of scientific weight. But in chemistry, the term normality is closely related to a few core che...

Relative mass is an important concept in chemistry. It exists to simplify the process of working out the mass of an atom or molecule. In absolute units, protons and neutrons have masses on the order of 10−27kilograms, which is a billionth of a billionth of a billionth of a kilogram, ...
Calculate the molarity of a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof the solute first. To convert grams to moles, the molar ...
Despite this feeling that things are not quite right it is impossible to restore normality or wake yourself up. Most of the time we are caught within the illogicality of the dream, unable to identify it as non-sense. Various writers have described this experience. A philosopher woke believing...
A 20% sugar solution has a volume of 500mL. How many grams of sugar does it contain?. Ans: Hint: Assuming the sugar to be glucose, find the mass of sugar in the respective volume of the solvent by calculating it for 20% solution and the correct answe...
were tested for normality (Q-Q plots) and homogeneity (Cleveland dotplots)41. Results Body condition and plasma metabolites No significant differences in body mass were observed between godwits from Fasted, Rice and Larvae groups at any stage (Table2): day of experiment onset (day 1; F2,19...
here's an image you might find interesting from P-92.6 where IUPAC determined by rule (1) that CH3 > H and by rule (5) R>S and called this thing "TRANS" not "E" in the PIN The rest of the chapter is focused giving examples of those 5 sequencing (or priority) rules. ...

Atoms are the building blocks of matter and are responsible for everything we observe in the visible universe. The two main components of an atom are the nucleus and the cloud of electrons. The nucleus contains positively charged and neutral subatomic pa
