Competition for oxygen
This experiment involves the reaction of a metal with the oxide of another metal. When reactions like these occur, the two metals compete for the oxygen. The more reactive metal finishes up with the oxygen (as a metal oxide). If the more reactive metal starts as the oxide then no ...

Resource
Stability and reactivity
Chemistry is a conceptual subject and, in order to explain many of these concepts, teachers use models to describe and explain the microscopic world and relate it to the macroscopic properties of matter. This resource is designed to provide strategies for dealing with some of the misconceptions that students have ...
