Chem Lab Experiments

Need subroutines for:
 - select lab (A, B, C, D)
 - information (list target substance, show chemicals available, show formulas)
 - get equipment ( beaker, flask, stopper with gas line or burner)
 - get burner (light and extinguish)
 - add chemical (solid, liquid or gas; input name OR formula; pass value to check for reaction)
 - reaction (phase change, color change, or explosion with reaction message pop-up)

General chemical behaviors UNLESS reaction occurs ...
solid + solid = bigger lump of solid in beaker or flask
solid + liquid = liquid
liquid + liquid = greater volume of liquid in beaker or flask
solid or liquid + gas = no visible difference (hissing sound may be needed)
gas + gas = no visible difference (hissing sound if possible or no change)
heating solid - no change or melt
heating liquid - bubbling
heating gas - increased pitch of hissing sound if sound used


Reaction possibilities ...
Phase change (solid to liquid, liquid to solid, liquid to gas)
Color Change
Explosion


Specific reactions detailed for each lab


A.  Chalk It Up

Raw materials:
calcium hydroxide (solid) CaOH
carbonic acid (liquid) H2CO3
nitrogen (gas) N2
hydrogen (gas) H2

Target substance: calcium carbonate (solid) CaCO3
Reactions:
calcium hydroxide (solid) + carbonic acid (liquid) = calcium carbonate (solid)
liquid combination turns back into white solid
no other combinations yield reaction

Message:
Just in time to save us from the sound of fingernails scraping on the chalkboard!
You made chalk!

B.  Pinch Hitting

Raw materials:

sodium hydroxide (solid) NaOH
hydrochloric acid (liquid) HCl
water (liquid)H2O
hydrogen (gas) H2
nitrogen (gas) N2

Target substance: sodium chloride (solid) NaCl
Reactions:  
sodium hydroxide (solid) + hydrochloric acid (liquid) = sodium chloride (solid)
liquid combination turns back into white solid
no other combinations yield reaction

Message:
Finger lickin' good!  You added just the right touch of sodium chloride.

C.  RATS!

Raw materials:

carbon (solid) C
lead (solid) Pb
sulfur (solid) S
nitric acid (liquid) HNO3
sulfuric acid (liquid) H2SO4
cardon dioxide (gas) CO2

Target substance: carbon disulfide (liquid) CS2
Reactions:
1.  carbon + sulfuric acid + heat from bunsen burner = sulfur dioxide and carbon dioxide
     liquid combination boils and produces some gas

2.  carbon + nitric acid + heat from bunsen burner = nitrous acid and carbon dioxide
     liquid combination boils and produces some gas

3.  sulfur + carbon dioxide + heat from bunsen burner = sulfur dioxide and carbon disulfide
     liquid combination boils and produces some gas 

Message:
1.  Ugh, cough.  You're polluting the air with sulfur dioxide and making CO2.  The rats keep coming.
2.  Nitrous acid eats holes in your lab coat and CO2 warms the air, but neither will get the rats!
3.  Sulfur dioxide smells rotten, but the carbon disulfied kills the rats.  Congratulations!

D.  Feed For Thought  - This one may be an extra ...  more on it later


Raw materials:

sulfur (solid)  S
sodium chloride (solid)  NaCl
iron oxide (solid)  Fe2O3
nitric acid (liquid)  HNO3
ammonium hydroxide (liquid)
fluorine (gas) Fl

Target substance: ammonium nitrate (solid)
Reactions:
