Predicting and balancing? Single replacement, double replacement, combustion, decomposition and synthesis... ex question my teacher did question:Sr(OH)2+H3PO4-> answer: 3Sr(OH)2+2H3PO4->Sr3(PO4)2+6H2O DOUBLE REPLAVEMENT
1) HCL+Ag->
2)Zn+HCL->
3)Na2SO4+CaBr2->
4)NaCLO3+H2->
5)Mercury(II) Oxide->
6)Sodium bromide reacts with chlorine to produce...
7)Iron(II) + Hydrochloric acid to produce...
8)Barium chloride + magnesium sulfate->
9)Hydrogen sulfate and barium hydroxide react to produce...

1. 2HCl + 2Ag -> 2AgCl + H2 single displacement
2. Zn + 2 HCl -> ZnCl2 + H2 single displacement
3. Na2S04 + CaBr2 -> CaSO4 + 2NaBr double displacement
4. 2NaClO3 + H2 -> 2HCl03 + 2Na single displacement
5. 2HgO -> 2Hg + O2 decomposition
6. 2NaBr + Cl2 -> 2NaCl + Br2 single displacement
7. Fe + 2HCl -> FeCl2 + H2 single displacement
8. BaCl2 + MgSO4 -> BaSO4 + MgCl2 double displacment
9. H2SO4 (sulfuric acid) + Ba(0H)2 -> BaS04 + 2HOH (water) double displacement
What! No synthesis?
3Zr + 2N2 -> Zr3N4

Uh, did you just do this student's homework for her? I'm new here, but I'm not sure that's the point.
