Read →⚗️ Mole Concept + Avogadro
Physical ChemistryWhat's happening? n = m/M. Each cell represents 10²² particles. 1 mole = 6.022 × 10²³ particles. This is the foundation of all stoichiometry.
⚛️ Bohr Atomic Model
Atomic StructureWhat's happening? ΔE = 13.6(1/n₂² - 1/n₁²). Electron jumps down = photon emitted. Jumps up = photon absorbed. The photon color depends on energy difference.
⚖️ Le Chatelier's Equilibrium
EquilibriumWhat's happening? N₂ + 3H₂ ⇌ 2NH₃. Increase pressure → shifts to fewer moles (right). Increase temperature → shifts to endothermic direction. This is Le Chatelier's principle in action.
🧪 pH Scale + Strong/Weak Acid
Acids & BasesWhat's happening? Strong acid: pH = -log[H⁺]. Weak acid: pH = ½(pKa - log C). Strong acids fully dissociate, weak acids only partially. Same concentration gives different pH!
⚡ Reaction Rate + Collision Theory
Chemical KineticsWhat's happening? Rate ∝ [A][B] × e^(-Ea/RT). Higher temperature = faster molecules = more collisions. Catalyst lowers activation energy = 10× faster. Watch the collision flashes!
🔥 Enthalpy Diagrams
ThermochemistryWhat's happening? ΔH = H(products) - H(reactants). Exothermic: products lower than reactants, heat released. Endothermic: products higher, heat absorbed. Ea is the energy barrier.
🔋 Galvanic Cell
ElectrochemistryWhat's happening? E°cell = E°cathode - E°anode. Electrons flow from anode (oxidation) to cathode (reduction) through the wire. Salt bridge completes the circuit.
📊 Periodic Trends Explorer
Periodic TableWhat's happening? Atomic radius decreases across a period, increases down a group. Electronegativity and ionization energy do the opposite. The heat-map shows the trend visually.
⚖️ Stoichiometry + Limiting Reagent
Mole ConceptWhat's happening? 2A + B → 2C. Compare moles/coefficient ratios. The smaller ratio is the limiting reagent. It determines how much product forms.
🧫 Titration Curve
Acids & BasesWhat's happening? Strong acid-strong base: equivalence at pH 7. Weak acid-strong base: equivalence at pH > 7. The steep part of the curve is where the indicator changes color.
