Document Summary

It is possible to rewrite the ideal gas laws equation in terms of mass (m) and molecular weight (m) instead of moles of gas (n) Under the conditions that the reactants and products are the same p&t, the volumes produced are proportional to the coefficients in the chemical equation. Gases react in volumes proportional to ratios of small whole numbers. The volumes of gasses involved in the reactions are proportional to the equation stoichiometry. The total pressure exerted by a gaseous mixture is equal to the sum of the partial pressures of each individual component in a gas mixture. The total pressure of two partial pressures is the direct sum of both of them. Gas has internal energy only due to kinetic energy of particles. Multiple connections can be made between the different parts of the equation: The temperature depends on the kinetic energy of the particles. Gas molecules at the same temperature have the same kinetic energy.
