Which equation represents a redox reaction 2AgNO3aq Cus CuNO32aq 2Ags BaCl2aq Na2CrO4aq BaCrO4s 2NaClaq H3PO4aq 3KOHaq 3H2Ol K3PO4aq CaCO3s CaOs CO2g?
The redox reaction can be identified by the transfer of electrons. In this case, the correct redox equation is: 2Ag(s) + 2NO3^-(aq) + 2BaCl2(aq) + Na2CrO4(aq) + 3H3PO4(aq) + 6KOH(aq) + 3CaCO3(s) -> 2Ag^+(aq) + 2NO3^-(aq) + Cu(NO3)2(aq) + BaCrO4(s) + 6NaCl(aq) + 3H2O(l) + 3K3PO4(aq) + 3CaO(s) + 3CO2(g).
