A. Argh! You've got to be kidding. This looks like your homework, not like you have a question about something you don't understand. I, and others on this forum, will be glad to help you to understand something you don't, but I'm not about to do your work for you. You need to dust off your solubility rules to do these. For instance, in the first one you have a double replacement reaction where silver ion will combine with iodide ion to make insoluble silver iodide. AgNO3(aq) + KI(aq) --> AgI(s) + KNO3(aq) Don't forget to include the state symbols.

NaPO4 + NiCl2 ------Balancing Ionic Equations?
Q. NaPO4 + CuSO4 ---> NaSO4 + Cu3(PO4) 2 CoCl2 + NaCO3 ---> CoCO3 + NaCl NaPO4 + NiCl2 ---> NaCl + Ni3(PO4)2 I have been trying to balance these equations to no avail. What am I missing? No matter what I have balanced there is always one that is coming back to bite me. What gives?! An instructions as to what I did wrong will be appreciated. I just need a new set of eyes at this point. I think I maybe be overlooking something Thanks!!

A. they're not random letters, those are the symbols of each element. like for number one, Cu is copper, and O is oxygen. all you have to do is make sure theres the same number of each element on each side of the yield sign (the arrow). thats how u balance. so Cu(s) + O2(g) -> CuO(s) is 1 Cu and 2 O on the left side, and 1 Cu and 1 O on the right side. There's an uneven number of O's on each side. so to balance it, just put a 2 in front of the CuO on the right side, so itll become: Cu(s) + O2(g) -> 2CuO (s) but now theres 1 Cu and 2 O on theh left side, and 2 Cu and 2 O on the right side. so now you have to balance out the Cu. just put a 2 in front of the Cu on the left side and you'll get: 2Cu(s) + O2(g) -> 2CuO(s) so now you have 2 Cu on… [cont.]

Last minute HELP!!! Balancing Double Displacement Reactions???
Q. I want to make sure I am doing them correctly. I have tried a few these on my own, but I'm not sure if there right? Directions: According to the solubility rules, predict whether a double displacement reaction will occur in each example below. If reaction will occur, complete and balance the equation, properly indicating gases and precipitates. If you believe no reaction will occur, write "no reaction"as the right-hand side of the equation. All reactants are in aqueous solution. a.) K2S + CuSO4 ---> b.) NH4OH + H2C2O4 --> c.) KOH + NH4Cl --> d.)NaC2H3O2 + HCL --> e.)Na2CrO4 + Pb(C2H3O2)2 ---> f.)(NH4)2SO4 + NaCl ---> g.)BiCl3 + NaOH --> h.)KC2H3O2 + CoSO4 --> i.)Na2CO3 + HNO3 ---> j.)ZnBr2 + K3PO4 -->
