Question 1

If the electrons in both half equations are the same, what can you do to form the full equation?

Answer 1

Add the two half-equations together

Question 2

What happens to the electrons?

Answer 2

They cancel out

Question 3

What about if the electrons are not balanced initially?

Answer 3

You have to multiply one (or both) half-equation by a constant so the electrons match
