RULES FOR WRITING AND BALANCING CHEMICAL EQUATIONS. Count the number of atoms of each element that appears as a reactant and as a product. If a polyatomic ion is unchanged on both sides of the equation, count it as a unit. Balance each element one at a time by placing coefficients in front of the formulas. No coefficient is written for a 1.

Experimental evidence can be used to identify products in a reaction. All reactions follow the Law of Conservation of Matter (balancing equations). Symbols are used to identify different aspects of a chemical reaction (states of matter, catalysts, heat, etc.). Collision theory describes characteristics for a successful reaction.

Chemistry Equations – Worksheet #1 Name _____ We have learned symbols for elements and to write formulas for compounds. Now we must learn to write equations to represent chemical reactions. Chemical reactions obey the Law of Conservation of Matter: matter is neither created nor destroyed during a chemical reaction.
