Exercise 7 Illinois Central College CHEMISTRY 130 Laboratory Section: ________ Page 1 Name ______________________ Evaluation of the Gas Law Constant Objectives In this experiment‚ we will determine the Ideal Gas Constant‚ R‚ which relates the number of moles of gas present to its volume‚ pressure and absolute temperature. Background To see how "R" was derived‚ we must look at the proportionalities defined by the other fundamental gas laws. For example‚ Charles’ Law showed us that the volume

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

F6/7 Chemistry Practical: Enthalpy of hydration of copper(II) sulphate Objective: To determine the enthalpy of hydration of copper(II) sulphate Group size: Individual Introduction This experiment enables an approximate determination of the enthalpy of hydration of copper(II) sulphate to be made. The enthalpy change when one mole of anhydrous copper(II) sulphate is dissolved in water is first determined. Secondly‚ the enthalpy of solution of copper(II) sulphate pentahydrate in water is determined

Chemical Composition of Natural Gas Natural gas is a naturally occurring gas mixture‚ consisting mainly of methane. While most of the gas supplied to Union Gas is from western Canada‚ some gas is supplied from other sources‚ including the United States and Ontario producers. While the gas from these sources has a similar analysis‚ it is not entirely the same. The table below outlines the typical components of natural gas on the Union Gas system and the typical ranges for these values (allowing for

Solar water disinfection Solar water disinfection is a type of water purification system that uses solar energy in order to make contaminated water safe to drink. This is done by eliminating contagious biological organisms such as bacteria‚ viruses‚ protozoa and worms. This process can only be taken place on biological agents non-biological agents such as toxic chemicals or heavy metals disinfection may not make all kinds of water safe to drink. Therefore additional steps away from disinfection
