Predicting Products – Single Replacement Reactions

A  +  BC   Arrow-3.png   AC  + B

Step 1 – Write the formulas of the reactants on the left side of the yield sign

Step 2 – Look at the Activity Series table to determine if the replacement can happen

Step 3 – If the replacement can occur, complete the reaction and balance it. 

If the reaction cannot occur, write NR (no reaction) on the product side.  Write complete BALANCED equations.
