Question

how to balance a equation ​

Answer 1

Balance charge. Add e- (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It's fine to change coefficients as long as you change them on both sides of the equation

Answer 2

Explanation:

First, see the number of molecules of elements on either side in the equation. To find out the number of molecules in the equation, see number of each molecule and then start balancing them at same time. While balancing an element, cross-check what are the changes being made into other elements as a result.
