● Stoichiometry is the use of quantitative relationships between substances that are involved in chemical reactions which determine the amounts of the reactants or the products (Bauer, Birk, & Mar ks, 2019). Stoichiometry - the process of determining the amounts of substances in a chemical reaction (Bauer, Birk, & Marks, 2019). ● It is used to relate the reactants and products by using calculations and balanced equations (Bauer, Birk, & Marks, 2019). ● By knowing the amount of a reactant o...

CHEM 103 MODULE 3 NOTES. 3.1: THERMOCHEMISTRY Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. In order to adequately discuss thermoch...
