Re:act Nuffield Advanced Chemistry
The Re:act Nuffield Advanced Chemistry website has now closed. However many of the resources are still available free of charge from RSC ChemNet , the Royal Society of Chemistry’s student network, including the Question & Answer service.
To access these resources, please visit the RSC ChemNet ReAct page  on MyRSC. To access the resources you will need to register for RSC ChemNet , which is free to join for students studying chemistry aged between 14-18.
The RSC are continuing to add more React resources to the RSC ChemNet site.
