1. Balance equation _Ag2+ ______Al —->Ag+ ___Al2S3

     1a) Explain how the above chemical reaction relates to the activity series of metals

 

2. If 1.356mol of Ag2S reacts with 0.772mol of Al, determine the theoretical yield of aluminum sullied using the steps :

- determine the limiting reactant

- determine made of aluminum sulfide

1. Balance the equation

___P2O2 + ___H2O —> __H3PO4

A) If 82.6 g of P2O5 reacts with 26.6 g of water, determine the theoretical yield phosphoric acid using the following steps: (Convert mass to moles for the reactants^^)

2. Determine the limiting reactant

3. Determine the mass of phosphoric acid (H3PO4) produced (the theoretical yield).

4. If the actual yield of H3PO4 was 80.6 g, determine the percent yield.
