chemistry-balanced redox equations
posted by princess .
Use the following steps to balance the redox reaction below:
Mg + Au+ Mg2+ + Au
a. Write the oxidation and reduction half-reactions. Make sure each half-reaction is balanced for number of atoms and charge
b. Multiply each half-reaction by the correct number, in order to balance charges for the two half-reactions.
c. Add the equations and simplify to get a balanced equation.
You need to learn how to do these yourself. What exactly do you not understand so we can get you started on th right foot.
Mg to Mg2+ loses 2 electrons
Au+ to Au gains one electron. So 2Au for each Mg
Mg yields Mg+ +2e
Au+ + e yields Au
so multiply the second equation by 2
