Study Notes
Stoichiometry
- Stoichiometry is the calculation of quantities in chemical reactions
- Chemical reactions involve the rearrangement of atoms
- Stoichiometry involves calculating quantities like moles, mass and volumes
- Balanced chemical equations show mole ratios between reactants and products
- Mole ratios are crucial for calculations
- Chemical formula relates atoms and molecules
- Mole is a unit for measuring amounts of a substance
- Molar mass relates mass to moles for a given substance
- Molar mass is the mass of 1 mole of a substance
- Calculations involve using the mole ratio from the balanced equation
- Limiting reactant is the reactant that is completely consumed first
- Excess reactant is the reactant that remains after the reaction
- Identifying the limiting reactant is important for determining the maximum product amount
- Empirical formula is the simplest whole-number ratio of atoms in a compound
- Empirical formula is derived from percent composition of elements
- Molecular formula shows the actual number of atoms in a molecule
- Molecular formula is a multiple of the empirical formula
- Stoichiometry calculations can involve gases
- Ideal gas law can be used to calculate volumes of gases involved in reactions
- Standard temperature and pressure (STP) conditions are often used
- At STP, 1 mole of any ideal has a volume of 22.4 L
