1. First look up the formulas involved

$AgNO_3$

$CaCl_2$

You need to know the valences of the metal ions. Normally treat the nitrate or other groups such as sulfate, carbonate, etc. as a single ion and not separate atoms

Then

$AgNO_3 \rightleftharpoons Ag^+ + NO_3^-$

$CaCl_2 \rightleftharpoons Ca^{+2} + 2 Cl^-$

$Ag^+ + Cl^- \right AgCl(s)$

Then put them together

$2AgNO_3 + CaCl_2 \,\rightleftharpoons\, 2Ag^+ + 2NO_3^- + Ca^{+2} + 2Cl^- \,\rightarrow\, 2AgCl(s) + Ca(NO_3)_2$

And you need to know the solubility of your main salts.

Most chlorides are soluble (with the exception of lead (II) chloride and silver chloride)
All nitrates are soluble.
Most sulfates are soluble (with the exception of barium sulfate, lead (II) sulfate and calcium sulphate)
All sodium, potassium, and ammonium salts are soluble.

There are others you need to know, but these are the basics.

Excel running balance formula [ 5 Answers ]

In Excel's help they have a running balance "how to" (below) but it requires the entry of a zero for fields not used. I'd like to do it like a checkbook register. How can I do it so that whether I enter a deposit or a withdrawal, the balance column will be updated? Thanks!
