8.01: Chemical Reactions Cheat Sheet
- Understand the Law of Conservation of Mass - Have you ever heard that mass can't be created or destroyed? In any chemical reaction, the total mass of the reactants equals the total mass of the products, so matter just transforms! Embrace this concept to balance equations like a pro.

- Master Balancing Chemical Equations - Think of chemistry like a game of balance: the number of atoms for each element must match on both sides of the equation. Use coefficients to give every atom its fair share and obey the conservation of mass. Practice with simple to complex reactions and watch your confidence soar!

- Recognize Different Types of Chemical Reactions - Synthesis, decomposition, single replacement, and double replacement are the four "flavors" you need to know (A + B → AB, AB → A + B, A + BC → AC + B, AB + CD → AD + CB). Spotting these patterns makes classification a breeze and turns memorization into a fun challenge. Mix and match reaction cards to test your skills! Wikipedia: Chemical Reaction Overview
- Identify Combustion Reactions - Combustion is chemistry's campfire: a substance burns in oxygen to unleash heat and light, often producing carbon dioxide and water. These exothermic reactions power engines, rockets, and even your barbecue grill. Recognizing the telltale "+ O₂ → CO₂ + H₂O" pattern will light up your reaction radar!

- Understand Exothermic and Endothermic Reactions - Energy in chemistry can be a party guest that either leaves the room (exothermic) or sneaks in (endothermic). Combustion is the life of the party, releasing heat, while photosynthesis is the shy introvert, absorbing energy. Classify reactions by their heat flow and you'll never be left out in the cold!

- Learn About Catalysts and Inhibitors - Catalysts are the party planners who speed things up without getting used up, while inhibitors are the gatekeepers that slow down or stall reactions. Understanding these helpers and blockers can transform your lab experiments from sluggish to spectacular. Master their roles to control reaction rates like a chemistry wizard!

- Explore Acid‑Base Reactions - When an acid meets a base, they throw a neutralization party to produce water and a salt. Look for proton transfers (H❺) to identify these reactions, and remember your pH scale as the guest list. Titrations and everyday antacids are just two examples of this dynamic duo at work! Centre Point Schools: Acid-Base Reactions
- Study Oxidation‑Reduction (Redox) Reactions - Redox reactions are electron transfer dramas where oxidation is the electron-departure event and reduction is the welcome-back party. Tracking electron flow with oxidation numbers helps you predict products and understand batteries, corrosion, and metabolism. Embrace the electron economy to ace these reactions! Centre Point Schools: Redox Reactions
- Understand Factors Affecting Reaction Rates - Temperature, concentration, surface area, and catalysts are like knobs you can turn to speed up or slow down reactions. Think of them as your reaction DJ - tweak the settings to find the perfect rate for your experiment. Learning to control these factors is the secret sauce of chemical kinetics!

- Recognize Indicators of Chemical Change - Color shifts, gas bubbles, precipitate formation, and temperature changes are the neon signs of a chemical reaction. Spotting these clues in the lab or in daily life - like rusting iron or baking bread - will sharpen your observational skills. Keep your eyes peeled and your notes ready!
