What actions should an exposed person take during the immediate aftermath of the explosion?
how to predict whether a precipitate reaction will occur when aqueous solutions of PbCl2 and (NH4)2S are mixed.
Consider an ideal gas which is allowed to expand slowly under constant temperature conditions. Derive an expression for the heat change for such a process, explaining any key stages in the derivation.
Many metals pack in cubic unit cells. The density of a metal and length of the unit cell can be used to determine the type for packing. For example, gold has a density of 19.32 g/cm3 and a unit cell side length a of 4.08 Å. (1 Å = 1. 10-8 cm.)
