3. Using the four steps used in the examples, determine what happens when a blue copper(II) nitrate (Cu(NO3)2(aq)) solution is mixed with a colorless solution of sodium sulfide (Na2S(aq)) Step 1: List the ions in the solutions Step 2: List the two possible products of the double replacement reaction Step 3: Determine which, if either, of the possible products will be a solid, liquid, or gas, and put (s). (1), (g), or (aq) to indicate what you have decided. Step 4: Write the three forms of the reaction equation: Molecular equation: Complete ionic equation: Net ionic equation
