I'm not sure if berillium oxide is readily soluble in ammonium acetate
http://en.wikipedia.org/wiki/Beryllium_oxide
If it is, then the products are Be(CH3COO)2, NH3 and H2O

Separate your equation into independent reactions and balance each. After that you can mix these reactions in any required proportions. C5H32 + O2 = CO2 + H2O C5H32 + O2 = CO + H2O Add nitrogen in required proportion: it is not participating in burning process, so it should be equal and unchanged in...

Iron in metal form is not found in nature. If the clay was found on a site of former construction, then it's certainly possible. Still, it's most likely that the magnetic particles are not Fe but Fe3O4 that forms during welding. Also, there is natural Fe3O4 (magnetite) http://en.wikipedia.org/wiki/M...

1) So what is going on with SuperIron out if it is not reduction for increased solubility? Both EDTA and citric acid form soluble chelates with iron II and III. Moderate acidic pH required for both cases. No need to reduce Fe III to II 2) Any thoughts on the amount of EDTA vs. clay? EDTA is very eff...

Ethanol azeotrope is 96% http://en.wikipedia.org/wiki/Azeotrope
If your distillation is ideal, 96% will be collected first and the rest (if you distill longer) will be pure water
