Write it out on a piece of paper and underneath each side of the equation write out how many of each atom there are. C 6 H 14 O 2- CO 2 H 2 O Step 1 balance carbon. Multiply the two half-reactions by the number that yields the lowest common number of electrons in each half-reaction.
Balancing is adding BIG numbers.
Look for elements you have been given a balancing number for Look elements that are changing oxidation number Look for elements that only appear once in reactants and products Mg 3Si 2O5OH 4 CO 2MgCO 3 SiO 2 H 2O Example 1 In this example we know the reactant Mg 3Si 2O5OH 4 has a balancing number of 1 so. These are the numbers we determine when balancing equations Your steps are. You see 6 carbons on the left so you know it will produce 6 CO 2. The instructions will examine balancing simple equations that contain 2 molecules for reactants and for products.
