2. part 3: double-displacement reactions: for each double-displacement reaction, describe what happened in each well, including the colors of any products that formed. if a chemical reaction occurred, write a balanced equation for it. then use the a, b symbols to write a general equation for a double-displacement reaction. here are the chemical formulas of the reactants for each reaction:

• sodium chloride – nacl

copper sulfate – cuso4

• sodium hydroxide – naoh

copper sulfate – cuso4

• sodium phosphate – na3po4

copper sulfate – cuso4

• sodium chloride – nacl

silver nitrate – agno3

• sodium hydroxide – naoh

silver nitrate – agno3

• sodium phosphate – na3po4

silver nitrate – agno3
