Practical Applications
## Counting Atoms in Reactions
Stoichiometry lets us calculate the exact amounts of reactants and products in a chemical reaction using balanced equations and molar ratios.
### Steps to Success
1. Balance the chemical equation.
2. Convert quantities to moles.
3. Use mole ratios to find unknowns.
4. Convert back to grams or liters as needed.
## Real-World Applications
- Baking: Recipes are like chemical equations; too much or too little of an ingredient changes the result.
- Industry: Manufacturing processes rely on precise chemical amounts to avoid waste.
Examples
- Determining how much oxygen is needed to completely burn methane.
- Calculating the amount of fertilizer needed for a specific crop area.
