--- FORMULAS & RULES ---
1. Name: Combustion Reaction Formula: Fuel + Oxygen -> Products Variables explained: Fuel (solid, liquid, or gas), Oxygen, Products When to use: To represent a reaction where a substance combines with oxygen to produce heat and light. Common trap: Forgetting the reactants or products.

1. Name: Neutralization Reaction Formula: Acid + Base -> Salt + Water Variables explained: Acid, Base, Salt, Water When to use: To represent a reaction where an acid reacts with a base to form a salt and water. Common trap: Confusing acid and base reactions.

2. Name: Law of Conservation of Mass Formula: Mass of Reactants = Mass of Products Variables explained: Mass of Reactants, Mass of Products When to use: To prove that mass is neither created nor destroyed in a chemical reaction. Common trap: Forgetting to consider the mass of reactants and products.

3. Name: Chemical Energy Formula: Energy = mc?T Variables explained: Energy, Mass (m), Specific Heat Capacity (c), Temperature Difference (?T) When to use: To calculate the energy released or absorbed in a chemical reaction. Common trap: Forgetting the units of energy.

4. Name: Electrochemical Cell Formula: E = E°(cathode) - E°(anode) Variables explained: Cell Potential (E), Standard Electrode Potential (E°) When to use: To calculate the potential difference between two electrodes. Common trap: Confusing the cathode and anode.

--- DIAGRAMS TO KNOW ---
1. Name: Electrochemical Cell Diagram Key labels: Anode, Cathode, Salt Bridge, Electrolyte What it illustrates: The transfer of electrons between two electrodes. Common exam focus: Identifying the anode and cathode.

1. Name: Periodic Table Key labels: Groups (1-18), Periods (1-7) What it illustrates: The relationship between elements and their properties. Common exam focus: Identifying the group and period of an element.

2. Name: pH Indicator Diagram Key labels: pH, Indicator Color What it illustrates: The range of pH values corresponding to different colors of an indicator. Common exam focus: Identifying the pH range of a given solution.
