Pick an element that is not equal on both sides of the equation. Add coefficients in front of the element and adjust your counts. Continue adding coefficients until you get the same number of elements on each side. Balance each equation. Be sure to show work. Remember you cannot add subscripts of place.

To balance the chemical equation, you must add COEFFICIENTS in front of the chemical formulas in the equation. You cannot ADD or CHANGE subscripts! Step 1: Determine number of atoms for each element. Step 2: Pick an element that is not equal on both sides of the equation.

Balancing Equations Practice (pdf) - A new version of Balancing Act that includes questions about subscripts and coefficients. An answer key is provided. Balancing Equations Challenge (pdf) - A worksheet to use after the Balancing Equations Practice to reinforce what the students have learned about balancing equations. An answer key is provided.

Balance each equation. Be sure to show your lists! Remember you cannot add subscripts or place coefficients in the middle of a chemical formula. Challenge: This one is tough! CO2 + H2O. 2 CaO. 2 NH3. 4 Cu + CO2. 2 H2O + O2. Hint: Add the O atoms on the product side together when doing the counts. 2 Na + MgF2 2 NaF + Mg.

Balancing Act ‘Overhead Key. Atoms are not CREATED or DESTROYED during a chemical reaction. Scientists know that there must be the SAME number of atoms on each SIDE of the EQUATION. To balance the chemical equation, you must add COEFFICIENTS in front of the chemical formulas in the equation.

How to Use the Balancing Act Worksheets. The worksheets are designed with a clear and concise format, providing an example followed by practice equations that increase in complexity. Here’s how students can use them effectively: Start with the Basics: Begin by identifying the number of atoms for each element present in the reactants and products.
