Chemical Changes, Physical Chemistry and Materials
A reaction-to-materials sequence with quantitative and particle-level explanations.
How can patterns in reactions help us choose, extract and engineer useful materials?
Reactivity, equations, energy and collision theory connect observable chemical change to particle explanations and decisions about materials.
