What will be the the net ionic equations for the following ones:- a) AgNO3 + KCl b) Ni(NO3)2 + Na2S c) CaCl2 + Na2CO3. 2) Write out the total ionic equation and cancel anything that is common on both sides Ca+2(aq) + 2Cl-(aq) + 2Na+(aq) + CO3-2(aq) --> CaCO3(s) + 2Na+(aq) + 2Cl-(aq)

Respuesta :

The molecular equation is

AgNO3(aq]+HCl(aq]→AgCl(s]+HNO3(aq]

How did I get this equation? Consider each reactant or product separately:

1 mole of AgNO3 contains 1 mole of Ag+ and 1 mole of NO−3 ions.

Ag+(aq]+NO−3(aq]+H+(aq]+Cl−(aq]→AgCl(s]⏐⏐↓+H+(aq]+NO−3(aq]

The net ionic equation is

Ag+(aq]+Cl−(aq]→AgCl(s]⏐⏐↓

Now try some of the others on your own
