produced‚ applying Dalton’s Law and the Ideal Gas Equation along with the application of the stoichiometric ratio between the electron and the gases‚ the fundamental electronic charge will be determined. THEORY H+ ions will join together at the cathode (the negative electrode) to produce H Atoms‚ and the H atoms will join to form molecules of H2 gas. At the positive electrode (the anode)‚ H20 molecules will decompose to replace the H+ ions lost and release O2 gas. The reactions appear below

The Gas Laws The Gas Laws 1. Boyle’s Law – P-V Relationship the pressure of a fixed amount of gas maintained at constant temperature is inversely proportional to the volume of the gas. The Gas Laws 2. Charles’ Law – T-V Relationship the volume of a fixed amount of gas maintained at constant pressure is directly proportional to absolute temperature of the gas. The Gas Laws 3. Gay-Lussac’s Law – P-T Relationship the pressure of a fixed amount of gas maintained

Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation ‚ where p is pressure‚ v is specific volume‚ c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel pressure vessel is discharged to the atmosphere

moles-stoichiometry-practice-problems Now you’re ready to use what you know about conversion factors to solve some stoichiometric problems in chemistry. Almost all stoichiometric problems can be solved in just four simple steps: 1.Balance the equation. 2.Convert units of a given substance to moles. 3.Using the mole ratio‚ calculate the moles of substance yielded by the reaction. 4.Convert moles of wanted substance to desired units. These "simple" steps probably look complicated at first
