    predicting and balancing equations
    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
