Document Summary

Filling most of the space is the electron. Isotopes: know the cations and anions ex: sulfate, phosphate, carbonate, hydroxide, ammonia, balance the charge of the cation and the anion. How many of each unit you have. Balanced chemical equation: 2h2 + o2 2h2o. Heat of reaction: 2h2 + o2 2h2o, delta h rxn. Ideal gas equation: pv = nrt, n = pv/rt. Empirical formula: total of moles, divide by smallest amount of moles. Deltah rxn = deltah (products) deltah (recatants) Use given reaction to make-up the desired reaction. Pv = nrt: v liters, p atmospheres, n moles, t - kelvin. D = p (mm) / rt: given on the formula sheet. Another formula you can use: p1v1/t1 = p2v2/t2. **molar volume: volume of one mole for any gas is 22. 4 l. Average kinetic energy of any gas is equal at the same temperature. Ex: h2so4 (aq) + 2naoh (aq) 2h2o + so4 2-(aq) + 2na+ (aq)
