● 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...

General Chemistry Semester 1 Exam Review | Latest Update | 2024/2025 | Graded A+ What is the difference between a heterogeneous and a homogeneous mixture, and how can each be separated? A heterogeneous mixture has visibly different components and can be separated by physical means such as filtration or decantation, while a homogeneous mixture has a uniform composition throughout and may require more complex methods like distillation for separation. How do you determine the empiric...
