Need help chemistry ionic and net ionic equations.?

Question

These are the equations I am having troble writing as ionic and net ionic equations.

1. NaBr + AgNO3 -- NaNO3 _ AgBr(s)

2. NiCl2 + 2KOH -- Ni(OH)2(s) + 2KCl

3. K2CrO4 + Pb(NO3)2 --PbCrO4(s) + 2KNO3

4. 3BaCl2 + Al2(SO4)3 --3BaSO4(s) + 2Alcl3

5. AgNO3 + Kl -- Agl(s) + KNO3

6. 2HCl + Ca(OH)2 -- H2O + CaCl2

Please help thanks!

Answer 1

Ionic equation:

break the reactants up into their two ions; don't forget to put the charges on the ions and use the coefficients from the balanced equation for both ions. Subscripts (unless part of a polyatomic ion) become coefficients. (see the example below)

the product that is the solid or water stays the same; break up the other compound into its two ions

Net ionic equation:

Look at your ionic equation. Find any ions that don't become part of the solid or the water. These are called "spectator" ions; cross them out. The remaining equation is the NET ionic equation.

ex. #2
Ionic equation:

Ni(2+) + 2Cl(1-) + 2K(1+) + 2OH(-1)=Ni(OH)2 +
2 K(1+) + 2(Cl(1-)

notice: the subscript for Cl in the NiCl2 became a coefficient
notice: the coefficient in front of the KOH goes in front of both the K and the OH in the ionic equation (same for the 2KCl).

Net ionic equation:
The K starts as an ion and ends up as an ion, unchanged. It is a spectator ion so cross it out on both sides of the equation. Same for the Cl. That leaves:

Ni(2+) + 2OH(-1)= Ni(OH)2(s)

Answer 2

Molecular Equation: FeCl3 (aq) + Na3PO4 (aq) -----> FePO4 (s) + 3NaCl (aq) total Ionic Equation: Fe3+ (aq) + 3Cl- (aq) + 3Na+ (aq) + PO43- (aq) ------> FePO4 (s) + 3Na+ (aq) + 3Cl- (aq) internet Ionic Equation: Fe3+ (aq) + PO43- (aq) ------> FePO4 (s) the only components which you harm up into ions are the soluble (aq) components. Be specific to incorporate the fee on each ion in the finished and internet ionic equations. components that are actually not broken aside are (s), (l), and (g). the internet ionic equation includes simplest the ions aggravating in forming the (s), (l), or (g). Ions that could be the comparable on the two area of the equation (spectator ions) are skipped over from the internet ionic equation.

1. Na+ + Br- + Ag+ + NO3- ===> Na+ + NO3_+ AgBr(s)
