balance ionic equatioons please really need these answers.

try harder. combine ions and see whether it will work. detailed answers cannot be given here. see forum rules

[zeshkani]

assign charges to the ions, and see what works together, and take out the spectator ions

something like this example:

CaCl2(aq) + 2AgNO3(aq) → Ca(NO3)2(aq) + 2AgCl(s)

Ca2+ + 2Cl- + 2Ag+ + 2NO3- → Ca2+ + 2NO3- + 2AgCl(s)  fully ionic equation

 and from this you can see whatever remains in solutions are spectator ions, so this equation can be reduced even more, try harder.

Try them yourself and if you don't get them, then people will help you. Dont expect people to do your homework.
