Introduction
Methods of characterization aim to calculate the products of a reaction. The level of detail expected depends on the circumstances, and calculates the range of methods required. If the aim has been to build a known compound, one needs to check its purity and identity. Fingerprinting techniques measure some other property or a spectrum and compare it with results published for known compounds and available in literature databases.
Elemental analysis
Elemental analysis is important in establishing identity of a known compound and the purity, or the empirical (stoichiometric) formulae of a new one. Elemental composition is generally quoted as percent by mass, from which the stoichiometry can be, calculate from atomic mass (RAM) values. Calculate a compound (X) with the following composition by mass:
Dividing each mass percent by the corresponding RAM (Appendix 1) gives the following relative molar quantities
These are very nearly in the proportions 1:9:6:3, suggesting a stoichiometric formula CrC9H6O3.
Maximum number of electrons present in N shell is: (1) 18 (2) 32 (3) 2 (4) 8 Ans: 32

CAN SOMEONE PLEASE EXPLAIN TO BE HOW THE LIBERMANNS CHEMICAL REACTION WORKS? I ALSO NEED ALOT ABOUT THE CHEMISTRY BEHIND THE REACTION, AND CANT FIND MUCH ONLINE.. PLEASE HELP ME
Atoms with the different numbers of neutrons and same atomic number are known as isotopes. The chemical properties of an element are determined by wildly the charge on the nucleus,
