Question: what is balancing equations? 

Answer: if you mean in chemistry, it refers to making sure that there is an equal amount of mass on both sides of the equation, so that none is lost during the reaction. all of the matter has to somehow get through to the other side, even if it winds up being a different state of matter (such as a solid precipitate being formed, or a gas given off.) if you need more help ask a teacher.
