Formulas for the substances undergoing the change (reactants) and substances generated by the change (products) are separated by an arrow and preceded by integer coefficients indicating their relative numbers. In a chemical reaction, the total number of each type of atom is conserved, and thus the mass does not change. Want to cite, share, or modify this book?

However, matter has other properties that you can observe only when the matter changes from one substance to another. How does the balanced equation relate to the law of conservation of matter? To begin, check that Reactant 1 is Sodium and Reactant 2 % If you are redistributing all or part of this book in a print format, A (n) chemical property is a characteristic of matter that can be observed as it changes to a different type of matter. What in the formula indicates that a reaction has taken place? 8pAH2:Id0Q@+ Q`RARLBG\)Hx`\+0 Introduction: It is important to distinguish chemical changes, in which new substances are formed, from physical changes, which do not create new substances. In a physical change, the substances remain the same.
