Balancing Reactions
![Page 2: Balancing Reactions. Choose the largest compound Make its coefficient 1 Choose any element in that compound that appears in only 1 other location.](https://reader035.fdocuments.us/reader035/viewer/2022062518/5697bf8f1a28abf838c8d471/html5/thumbnails/2.jpg)
Balancing Reactions• Choose the largest compound
• Make its coefficient 1
• Choose any element in that compound that appears in only 1 other location
![Page 3: Balancing Reactions. Choose the largest compound Make its coefficient 1 Choose any element in that compound that appears in only 1 other location.](https://reader035.fdocuments.us/reader035/viewer/2022062518/5697bf8f1a28abf838c8d471/html5/thumbnails/3.jpg)
•Balance that element with coefficients where that element appears
•Repeat until all elements are balanced
•Double if on half-unit
