📚 Quick Study Guide

  • ⚖️ Stoichiometry is the study of the quantitative relationships between reactants and products in chemical reactions.
  • ⚗️ Balanced chemical equations are essential for stoichiometric calculations. Make sure your equation is balanced before proceeding!
  • 🔢 The coefficients in a balanced equation represent the mole ratios between substances. For example, in the reaction $2H_2 + O_2 \rightarrow 2H_2O$, 2 moles of $H_2$ react with 1 mole of $O_2$ to produce 2 moles of $H_2O$.
  • ⚗️ Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). You can calculate it by summing the atomic masses of all atoms in the chemical formula.
  • 🌡️ Standard Temperature and Pressure (STP) is defined as 0°C (273.15 K) and 1 atm pressure. At STP, one mole of any gas occupies 22.4 L (Molar Volume).
  • 📐 Limiting reactant is the reactant that is completely consumed in a reaction. It determines the maximum amount of product that can be formed.
  • 📈 Percent yield is the ratio of the actual yield (experimental) to the theoretical yield (calculated), expressed as a percentage: $\text{Percent Yield} = (\frac{\text{Actual Yield}}{\text{Theoretical Yield}}) \times 100$
