For the following problems, show all work (as done in previous homework) to: 
a)Determine if reaction occurs or show balanced chemical reaction 
b)Do a net ionic reaction 
c)Perform stoichiometric problems as if the reaction did (or does) occur 
 
 
1) If 32.5g sodium sulfide is added to copper (II) acetate (as much as needed to react), how many grams each product do you have? 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
2) If you react 56.3L of fluorine gas (@STP) with calcium chloride (enough for reaction), how many liters of the gas product and grams of the solid/liquid/aqueous product do you make? 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
3) If you react 72.3g ammonium nitrate with potassium carbonate (enough to react), how many grams of each product do you make?
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
1) Products: <nowiki>NaC</nowiki>2H3O2(aq) , <nowiki>CuS</nowiki>(s), Coeff: 1,1,2,1, Net Ionic: 1 S2- + 1 Cu2+ --> 1 Cu1S1(s), 40.0g <nowiki>CuS</nowiki> and 68.3g <nowiki>NaC</nowiki>2H3O2.

2) Products: <nowiki>CaF</nowiki>2(aq), Cl2(g), Coeff: 1,1,1,1, Net Ionic: 1 F2(g) + 2 Cl1- --> 2 F1- + 1 Cl2(g), 56.3 L Cl2 @STP, 196g <nowiki>CaF</nowiki>2

3) Products: <nowiki>KN</nowiki>O3(aq), (NH4)2<nowiki>CO</nowiki>3(aq), Coeff: 2,1,2,1, Net Ionic: All cancel out, No Reaction, 91.3g <nowiki>KNO</nowiki>3, 43.3g (NH4)2<nowiki>CO</nowiki>3(aq)
