Bringing Balance To the Force... And Equations

What are phase symbols?

Phase symbols are subscripts that indicate the phase of the chemical.


    Ex. Al(s) - Solid      H20(l) - Liquid     H2(g) - Gas     AgNO3(aq)Aqueous


Chemical equations from word equations


Solution means something dissolved in water and therefore is an aqueous phase.

1.     Chemical equations must include phase symbols and a balance of the equation.
2.     Diatomic molecules : H2, N2, O2, F2, Cl2, Br2, I2
3.     Polyatomic molecules : P4, S8

Examples:


1) A solution of barium phosphate is mixed with aqueous sodium sulphate to yield solid barium sulphate and aqueous sodium phosphate.


Ba3(PO4)2 (aq) + 3Na2SO4 (aq)   =>  3BaSO4 (s) + 2Na3PO4 (aq)


2) A solution for aluminum chloride, carbon dioxide, and water can be prepared mixing pure aluminum carbonate with a solution of hydrochloric acid.

Al2(CO3)3 (s) + 6 HCI (aq)  =>  2 AlCI3 (aq) + 3 CO2 (g) + 3 H2O 


If you seek balancing beyond chemical equations young Jedi, perhaps it is time for you seek out the force.

When you are your done doing that, try honing your skills on the beautiful planet of Alderaan. Oh wait... Just go to the Dagobah system.
