Re: Impossible? Reactants of this Equation?

Phosphoric acid + Calcium hydroxide.

What are the reactants of this equationa and how would I balance them?
You need to write an unbalanced equation:
H3PO4 + Ca(OH)2 = Ca3(PO4)2 + H2O
and then balance this equation here

Al + KOH + H2SO4 + H2O ---> KAl(SO4)2 * 12H2O + H2
You should enter it as:
Al + KOH + H2SO4 + H2O = KAl(SO4)2(H2O)12 + H2

Just rewrite Na2S2O3•5H2O as Na2S2O3(H2O)5:
S8 + Na2(SO3) + H2O = Na2S2O3(H2O)5
and balance it here:

It's not possible to balance it AS IS, because there are 2 mistakes:
Al2Cl3 -> AlCl3
Ba2(SO4) - > BaSO4
Anyway here is the answer:

Rb & Cs explosion

Here is a nice video showing how Rb and Cs react with water: Alkali metals in the water: Li, Na, K, Rb, Cs Although the show looks really nice, I do not believe that demonstrated explosions can be really produced by reaction of Rb or Cs with water. It seems to me that they used industrial explosives...
