0 a chemical equation that has an equal amount of each element on the left and right sides -- 平衡的化学方程式（方程式左右两边每种元素的数量相等）
For zipped monads, is a taut presentation given by balanced equations in which both sides have the same number of leaves necessarily a shaped presentation?
A properly balanced equation would take these factors into account.
Therefore, the same charge must be present on both sides of the balanced equation.
