Advice on balancing chemical reactions Takes practice. The quickest approach can vary. General guidelines: 1. Leave the more complicated formulas “as is”, and use the less complicated formulas to try to “fill in.” 2. Keep polyatomic ions as intact units. Practice : C 12 H 22 O 11 + O 2 CO 2 + H 2 O

Chemistry 101 Fall 2010 2 Review of Chapters 1-3: Ratios within a compound The compound CO 2 has these ratios … 1. 1 atom of C for every 2 atoms of O. 2. 6.022 x 10 23 atoms of C for every 12.044 x 10 23 atoms of O. 3. 1 mole of C atoms for every 2 moles of O atoms. 4. 12.0107 grams of C for every 32.9988 grams of O. The chemical formula CO 2 tells us all this information. Saying it another way, 1 CO 2 : 1 C : 2 O, or _1 C_ _ _2 O _ _1 C _ 1 CO 2 1 CO 2 2 O *N A and Molar Mass (MM) allow us to convert between atoms <--> moles <--> grams.
