## 概述

Interactive visualization of gas preparation in laboratory - Explore experimental apparatus with reaction flask and delivery tube, gas generation through chemical reactions, bubble animation showing production rate, collection methods (water displacement for insoluble gases like H₂ and O₂, upward air displacement for lighter-than-air gases like H₂, downward air displacement for heavier-than-air gases like CO₂), production rate calculation (r = k·[reactant]), volume of gas calculation (V = nRT/P), temperature effect on rate (Arrhenius equation k = A·e^(-Ea/RT)), bubble frequency dependence on surface area (f ∝ r/A_surface), common laboratory gases (hydrogen H₂ from Zn + H₂SO₄, oxygen O₂ from 2H₂O₂ decomposition, carbon dioxide CO₂ from CaCO₃ + HCl), gas properties (formula, solubility, density, typical reaction), real-time apparatus animation with reaction flask, thistle funnel, delivery tube, and collection vessel, bubble visualization with gas molecules, flow direction arrows, and comprehensive educational content covering gas preparation principles, collection method selection based on gas solubility and density, production rate kinetics, safety precautions for flammable gases (H₂), oxygen-supporting combustion (O₂), and asphyxiation hazards (CO₂), and real-world applications in fuel cells, medical respiration, carbonation, and industrial processes. Features adjustable parameters for reactant concentration (0.1-5.0 M), temperature (0-100°C), surface area (0.1-5.0 cm²), rate constant k (0.1-3.0 s⁻¹), bubble size (0.5-2.0x), animation speed (0.2-3.0x), gas type selection (H₂, O₂, CO₂), collection method selection (water/upward/downward displacement), and display options (show gas molecules, show reaction animation, show gas flow direction, enable bubble sound). Multi-language support (en, zh, es, fr, de, ru, pt). Perfect for chemistry education, laboratory training, and understanding gas preparation techniques
