Why is stoichiometry important? Stoichiometry: Stoichiometry is a part of chemistry that tells us the relationship between the reactants and products in a chemical reaction or process. Stoichiometry is a basis for calculating many related parameters and allows a quantitative relationship these reactant...

CaSO4·2H2O + heat → CaSO4·0.5H2O + 1.5H2O I have seen variously, 140-180C, 600F, 600C, 650C, etc, It's all over the map. Wikipedia says "about 150C" -- but is is that even right and is there a more specific temperature, derived from the formula for the reaction itself?
(A) CaO, Ca(OH)2 e CaSO4.(B) Na2O, NaOH e Na2SO3.(C) Na2O2, NaOH e Na2SO4. <--- this is the answer(D) Al2O3, HalO2 e Al2 (SO4)3.(E) K, KOH e K2SO4. I know reactions with peroxides; so, if I add both equations, it is very easy to see which one is the ans...
