Writing Net Equations

Before we start with out net equations, we have to be able to identify its states.

Now, how do we do that??

WELL . . . 

u can use the table of Solubities, which was given by Ms Chen.

The anions can be found in the left hand column, the cation in the second column and then you can continue buy following its presense of absense to the word soluble or non-soluble.

if the result is soluble: then its aqueous

if the result is non soluble: then its solid

( Now were on the exciting part)

WRITING NET EQUATIONS!

FINALLY!

(woooh)

So, for starters there is only a net equation when you have a precipitation.

( keep that in mind)

Also, MAKE SURE ( when ur balancing) that aq ions that are the same on BOTH SIDES gets cancelled out.

Here are some practices.

( Like what Ms Chen once said  " Practice makes u better, but not PERFECT" )

so PRACTICE EVERYONE! (:

Fe(s) + 2AgNO₃(aq) ® 2Ag(s) + Fe(NO₃)₂(aq)

Net Ionic Equation: Fe(s) + 2Ag⁺(aq) ® 2Ag(s) + Fe²⁺(aq)

CaCO₃(s) + 2HCl(aq) ® CaCl₂(aq) + H₂O(l) + CO₂(g)

Net Ionic Equation: CaCO₃(s) + 2H⁺(aq) ® Ca²⁺(aq) + H₂O(l) + CO₂(g)

2Na3PO4 (aq) + Ca9NO3)2 (aq) -> 6NaNO3 (aq) + Ca3(PO4)2 (S)

Net equation: 3Ca 2+ (aq) + 2 PO4 3- (aq) -> Ca3(PO4)2 (s)
