Problem-Solving Patterns

Stoichiometry Problems

1. Write balanced equation
2. Convert given to moles (using molar mass or molarity)
3. Use mole ratio from balanced equation
4. Convert to requested units

pH Calculations

Redox Balancing (Acidic Solution)

1. Separate into half-reactions
2. Balance atoms except O and H
3. Balance O with H₂O
4. Balance H with H⁺
5. Balance charge with e⁻
6. Multiply to equalize electrons
7. Add half-reactions

Common Notation

Lewis Structure Steps

1. Count total valence electrons
2. Draw skeleton structure (central atom)
3. Place bonding pairs
4. Distribute remaining electrons as lone pairs
5. Check octets (or duets for H)
6. Form multiple bonds if needed
