A ___________ ____________ tells the story of a chemical reaction. __________ are the starting substances in the reaction while ________ are the new substances that are formed. The large numbers in front of some of the formulas are called _____________. These numbers are used to _______ the equation because chemical reactions must obey the Law of ______________ of Matter. The number of atoms of each element on both sides of the equation must be ________ because matter cannot be ________ or ___________. When balancing equations, the only numbers that can be changed are ________; remember that __________ must never be changed in order to balance an equation.
I know this is a long question but I really need help. Thanks so much. ❤️

Answer:
A Chemical Equation tells the story of a chemical reaction. Reactants are the starting substances in the reaction while Products are the new substances that are formed. The large numbers in front of some of the formulas are called Coefficients. These numbers are used to Balance the equation because chemical reactions must obey the Law of Conservation of Matter. The number of atoms of each element on both sides of the equation must be Equal because matter cannot be Created or Destroyed. When balancing equations, the only numbers that can be changed are Coefficients; remember that Subscripts must never be changed in order to balance an equation.
