final practice explaination of stoichiometry
https://www.youtube.com/watch?v=zv-Z-eaE_RE&t=33s Stoichiometry (Greek: stoicheon: element, metrain: measure) is a chemical field that studies the quantitative aspects of an element in a compound or reaction. In other words, stoichiometry is a chemical calculation involving the quantitative relation of substances involved in the reaction. Stoichiometry includes basic chemical laws that indicate quantitative relationships within it. The laws are as follows: Stoichiometry - Basic Law of Chemistry 1. The Law of Conservation of Mass In 1774, a scientist from Francis Lavoiser conducted an experiment by heating Tin and Oxygen gas in a recluse. From the results of his experiment, Lavoiser found that there was no mass change in his experiments. Then he puts the so-called Mass Conservation Law, which reads: "In chemical reactions, the mass of reactants is equal to the mass of the reaction product" 2. Comparable Law of Comparison In contrast to Lavoiser, Prous...
