Calculate the work done in joules by the reaction when 0.35 g of Na reacts with water to form hydrogen gas at 5°C and 2.5 atm. 2 Na(s) + 2 H2O(l) 2 NaOH(aq) + H2(g)
Describe the preparation of 250 mL of 0.6 M triethanolamine buffer, pH 7.2, from the free amine and 1.0 M HCl (pK for the amine hydrochloride is 7.80).
When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV1.4 = C, where C is a constant. Suppose that at a certain instant the volume is 600 cm3 and the pressure is 80 kPa and is de..
