Complete and balance the following chemical equations. Include the correct state

Question

Complete and balance the following chemical equations. Include the correct state notations for each of the products. Each reaction results in only one precipitate and only one soluble compound: a) Sr(NO3)2(aq) + (NH4)2C2O4(aq) b) Ba(NO3)2(aq) + H2SO4(aq) c) Ca(NO3)2(aq) + K2CrO4(aq) d) Pb(NO3)2(aq) + Na3PO4(aq) e) AgNO3(aq) + LiBr (aq) f) Mg(NO3)2(aq) + Na2CO3(aq)

Explanation / Answer

a)Sr(NO3)2(aq) + (NH4)2C2O4(aq) --> SrC2O4(s)? + 2 NH4NO3(aq) The total ionic equation Sr+2(aq) + 2 NO3-1(aq) + 2 NH4+1(aq) + C2O4-2(aq) --> SrC2O4(s) + 2 NH4+1(aq) + 2 NH4+1(aq) The net ionic equation(CANCELLING SPECTATOR IONS) Sr+2(aq) + C2O4-2(aq) --> SrC2O4(s) b) H2SO4(aq) + Ba(NO3)2(aq) ? BaSO4?(s) + 2HNO3(aq) c)K2CrO4(aq) + Ca(NO3)2(aq) ---> 2KNO3(aq) + CaCrO4(s)? Ion : 2K(+) + CrO4(2-) + Ba(2+) + 2NO3(-) --> 2K(+) + 2NO3(-) + BaCrO4 Net Ionic: CrO4(2-) + Ba(2+) --> BaCrO4 d)3 Pb(NO3)2(aq) + 2 Na3PO4(aq) --> Pb3(PO4)2(s)? + 6 NaNO3(aq) Ion:3Pb(2+)(aq) +2 PO4(3-)(aq) --> Pb3(PO4)2(s)? e)LiBr(aq) + AgNO3(aq)--> LiNO3(aq) + AgBr(s)? f)Mg(NO3)2 (aq) + Na2CO3 (aq) ? MgCO3 (s)? + NaNO3 (aq)
