Remember to include the state (i.e. (s) ). If no precipitate is formed, write NO REACTION. --------- Write the formula for the precipitate (if any) from the reaction of CoCl2(aq) and Na3PO4(aq). Write just the precipitate (not the whole reaction). Remember to include the state (i.e. (s) ). If no precipitate is formed, write NO REACTION. ---------- Write the formula for the precipitate (if any) from the reaction of CuNO3(aq) and (NH4)2S(aq). Write just the precipitate (not the whole reaction). Remember to include the state (i.e. (s) ). If no precipitate is formed, write NO REACTION.

You are in lab and ready to mix a beaker containing a solution of sodium cyanide with a beaker containing a solution of cobalt (III) acetate. You mix 45.0 mL of a 6.32 M solution of the sodium cyanide with an excess amount of cobalt (III) acetate. 1. Write out the balanced molecular reaction (including all physical states) for this reaction. 2. Calculate the amount of moles of sodium cyanide that was added into the mixture. 3. Calculate the minimum amount of moles of cobalt (III) acetate required to completely react the sodium cyanide. 4. Calculate the mass, in grams, of the solid produced from the reaction.
