PREDICTING PRODUCTS REVIEW SHEET
For each of the following reactions, write the type of reaction. Then predict the
products and write the overall balanced equation. For single and double
replacements reactions, use the attached activity series and solubility information
to predict whether or not they occur. Write "NR" if no reaction will take place and
explain why doesn’t occur.
