Vocabulary
- Stoichiometry — The calculation of quantities of reactants and products in chemical reactions.
- Molar Ratio — A ratio between the amounts in moles of any two components involved in a chemical reaction, derived from the coefficients in a balanced chemical equation.
- Molar Mass — The mass of one mole of a substance, typically expressed in grams per mole (g/mol).
- Balanced Chemical Equation — A chemical equation in which the number of atoms for each element and the total charge are the same for both the reactants and the products.
Questions
Watch the video carefully and answer the following questions based on the content presented.
