1. Experimental investigation of the rate of effusion of gases, molecular mass and its effect on effusion rate, data collection on different gases with various molecular masses.
2. Laboratory setup for measuring reaction rates, analyzing the effect of temperature on reaction speed, and plotting graphs for visualizing the relationship between reaction rate and temperature.
3. Data collection methods, ensuring consistent conditions across multiple trials, proper volume measurements, and the calculation of reaction rates.
4. Calculation of molar amounts from mass and volume, determination of the oxidation state of lead in various lead oxides, and plotting graphs for visualizing data.
5. Qualitative analysis of anions and cations, using reagents like sodium hydroxide and ammonia for identifying ions in a solution, testing with specific reagents to identify halide ions.
