Answer 1 To balance an equation means that there are the same number of each element on each side. The reason a subscript cannot change is that it represents the amount of an â¦ element within a certain compound in relation to any other elements. If that ratio changes, it is no longer the same compound.Changing a subscript changes a formula so that it no longer stands for the correct substance. Answer 2 The point of balancing an equation is to find the ratios in which chemicals will react or be produced. By changing the equation, you change the reaction.Therefore you are not trying to balance the same reaction. Answer 3 A balanced chemical equation is the standard way of writing equations for chemical reactants because it follows the LAW OF CONSERVATION OF MASS. subscript in the formula can not be changed when balancing an equation because changing a subscript would make the formula describe a different compound, or rather more likely a non-existent compound.
Chemical equations do not come already balanced. This must be done before the equation can be used in a chemically meaningful way. All chemical calculations to come must be done with a balanced equation. A balanced equation has equal numbers of each type of atom on each side of the equation.The The Law of Conservation of Mass is the rationale for balancing a chemical equation.his must be done before the equation can be used in a chemically meaningful way. All chemical calculations to come must be done with a balanced equation. A balanced equation has equal numbers of each type of atom on each side of the equation.
