In order to calculate the molar mass of any compound, we only need to know what elements are contained in the compound and what the molar mass of the elements are. Answer and Explanation: The molar mass of sucrose is 342.2965 g/mol. Let's look at the math. ...
Raman spectra showing some of the chemical species within a suspected counterfeit tablet. We identified the red spectrum as CaSO4 by searching against Renishaw's inorganic materials and minerals library. Raman spectra of two polyethylene samples showing differences in intensities and band widths. These ...

(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...
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?
