-Alchemy is an ancient study or art which attempted to combine science and philosophy to solve worldly problems
. Alchemists used science and philosophy to study how to change basic substances (such as metals) into other substances. They also studied how substances (and how they are changed into other substances) were related to magic and astrology.
Standard equation would be N2(g)+3H2(g)==>2NH3(g), so through stoichiometry, (4 mol N2)(2mol NH3/1 mol N2), assuming excess H2, would yield 8 moles of NH3.
