Translating Equations

Translating equations just basically means converting a formula to a word equationa and vice versa. 
Let's review.

Step 1: write the formula of the reactants and the products.
silver nitrate + potassium chromate --> silver chromate + potassium nitrate

  +  
AgNO3 + K2CrO4 --> Ag2CrO4 + KNO3

Step 2: balance the equation.
2AgNO3 + 1K2CrO4 --> 1Ag2CrO4 + 2KNO3

Step 3: write in the states.
2AgNO3(aq) + 1K2CrO4(aq) --> 1Ag2CrO4(s) + 2KNO3(aq)

Step 4: add all other values if neccessary(enthalpy)
Complete ionic equation:
-all the reactants and all the products
Take this example:
Ba(NO₃)₂ + CuSO₄ BaSO₄ + Cu(NO₃)₂
the complete ionic equation is
Ba²⁺ + 2 NO₃^- + Cu²⁺ + SO₄^2- BaSO₄ + Cu²⁺ + 2 NO₃<sup>-
Often however, you won't have to write this all out.
Net ionic equation
-only looks at the elements forming a solid.2Na1+_(aq) + SO₄2-_(aq) + Ba2+_(aq) + 2Cl1-_(aq) -----> 2Na1+_(aq) + 2Cl1-_(aq) + BaSO_4(s)
- we can all agree that this is the complete ionic formula, but what is the net ionic formula?
Ba2+_(aq) + SO42-_(aq) -----> BaSO_4(s)</sup>

^{Try several of these problems! List the type of reaction and write a net ionic equation for each.}

1)         ____ NaBr + ____ Ca(OH)₂ à

2)           ____ NH₃+ ____ H₂SO₄ à

3)           ____ Pb + ____ H₃PO₄ à

4)           ____ Li₃N + ____ NH₄NO₃ à

^{The optimist sees the glass half full.
The pessimist sees the glass half empty.
The chemist see the glass completely full, half in the liquid state and half in the vapor state.}
