Cheat Sheet
- Stoichiometry & Limiting Reactants -
Stoichiometry is the backbone of chemical problem-solving, letting you convert moles of reactants to products using balanced equations. Identify the limiting reagent by calculating the theoretical yield for each reactant; the smaller yield designates the limiting reactant. A quick check: compare the moles available versus the moles required to predict product formation accurately.
- Newton's Laws of Motion -
Newton's laws form the foundation for many physics challenges, with the second law explaining acceleration under force (F = ma). Action and reaction forces always occur in pairs, which is crucial for collision and motion problems. Recall "every action has an equal and opposite reaction" as a handy mnemonic during tense science olympiad questions.
- DNA Replication & Base Pairing -
DNA replication follows a semiconservative mechanism in which each daughter molecule retains one parental strand. Key enzymes like helicase, DNA polymerase, and ligase work in concert to ensure high fidelity. Use the mnemonic "Apples in the Tree, Cars in the Garage" to remember A - T and G - C base pairings for biology scenes in the science olympiad quiz.
- Gibbs Free Energy & Thermodynamics -
Gibbs free energy (ΔG = ΔH - TΔS) predicts whether a reaction is spontaneous under constant temperature and pressure. A negative ΔG indicates a spontaneous process, while a positive ΔG signifies nonspontaneity. NIST chemistry tables provide reliable ΔH and ΔS values to practice calculating ΔG ahead of competition.
- Periodic Trends & Electronegativity -
Electronegativity and ionization energy generally increase across a period and decrease down a group in the periodic table. Remember the mnemonic "FONClBrISCH" (Fluorine, Oxygen, Nitrogen, Chlorine, Bromine, Iodine, Sulfur, Carbon, Hydrogen) to quickly rank elements. Mastering these trends helps you predict bond polarity and reactivity in diverse science olympiad questions.
