Aranda, Alfonso; Rodriguez, Maria del Prado – Journal of Chemical Education, 2006
The practical scenarios discussed in a chemistry or chemical engineering course that use solid or liquid reactants are presented. Important ideas to be considered when handling pressurized fluids are provided and three typical examples are described to enable students develop secondary skills such as the selective search of data, identification of…
