Part 3 - Single vs. Double Replacement Reactions
In the chart below, pick the correct chemicals to perform a reaction. If a Single Replacement reaction occurs, type "SR" in the box. If a Double Replacement reaction occurs, type "DR" in the box. If nothing happens, type "NR" in the box. When finished, make sure to type your answers to the questions below! (Hint - record under any conditions!)

What did you look for to determine if a reaction was a single replacement reaction?
What did you look for to determine if a reaction was a double replacement reaction?
Some reactions in this demonstration did not immediately work, so what did they do to "force" some reactions to occur?
