Reversible Reactions & Dynamic Equilibrium Reversible reaction Some reactions go to completion where the reactants are used up to form the products and the reaction stops when all of the reacta...
Oxidising & Reducing Agents Oxidising agent An oxidising agent?is a substance that?oxidises?another atom or ion by causing it to lose electrons An oxidising agent itself gets?reduced – gains el...
Balancing Redox Reactions Oxidation numbers can be used to balance chemical equations Roman numerals between brackets are used to show the ox. no. of an atom that can have multiple oxidation states...
Oxidation Numbers The oxidation numbers (also known as oxidation state) is a number given to each atom or ion in a compound to keep track of how many electrons they have In a single ion or molecula...
