Class Notes
... The law of conservation of mass (aka: the law of conservation of matter) says that during a chemical reaction or a physical change mass is conserved; mass is neither created nor destroyed. This implies that the atoms that were there in the reactants (before the chemical change) must be there in the ...

... Transition metals exhibit variable oxidation states of differing stability. Compounds of the same transition metal but in different oxidation states may have different colours. Oxidation can be considered as an increase in oxidation number and reduction can be considered as a decrease in oxidation n ...
