Chemical compound formulas provide a shorthand communication for the structure of molecules and compounds. Reading and writing the chemical formula of compounds requires just a little understanding of the language of chemistry. Definitions of Terms Science depends on precision of language to communicate ef...

How do elements combine to form compounds? How are chemical elements classified? How are natural elements formed? How do atoms of different elements differ? How are chemical elements named? What does a chemical change always result in?
Wait until the glycerin has come to a boil, which should take 10 minutes, and then turn the heat down to low. The glycerin will begin to become a liquid and mesh together with ammonia. Add ¼ oz. of ammonia compound to the heated glycerin beaker, and then mix the two compounds toget...
Show activity on this post. The standard example is CrCl3⋅6H2OCrClX3⋅6HX2O, which can have three distinctly different crystalline compounds now known as [Cr(H2O)6]Cl3[Cr(HX2O)X6]ClX3 (violet), [CrCl(H2O)5]Cl⋅H2O[CrCl(HX2O)X5]Cl⋅HX2O (blue-green), and [Cr...

Molarity is a familiar way to express concentration in chemistry. Take the number of moles, which is obtained from the molar mass, and divide by the number of liters. Normality takes into account reactive equivalents. The normality formula is N = Mn, wer
Building Molecules & Compounds When the social atoms and elements hang out together, they might link up to form a molecule. A molecule is comprised of at least two atoms joined together by a chemical bond, like the letters that build different words, the atoms of elements build different mo...

(thank you referee 3! Your suggestion proved one of the most compelling cases we carried out on RoboChem). We once again meticulously isolated the compounds to validate the RoboChem results and submitted a revised version along with a rebuttal addressing all the questions. And then, th...
