Dear sirs, I've detected an error in my post. I am sorry. I mixed up mineral and gas. 1) Determine mineral A and gas B I also want to say that gas and matter have the same meaning - it is B. I think that problem says that B has different structures in liquid and gaseous phase. All the...

Points 2), 3) and 4) of this task I can solve if I know what the matters A and B. So it is necessary to solve point 1). I tried to use Mendeleev-Klapeiron equation, through density it becomes following: M = ρRT/p But for each occasion I've got... different molar masses! Explain please if...

One hundred thousands denarii (or 423 kg of gold) cost a vase from mineral A in Ancient Rome. A Painter in 17th century occasionally got from it gas B and Physicist in 19th told an assumption of its composition. There are experimental data of pressure of its saturated steam and density over a...

Okay, thank you very much. May be, somebody has another point of view?

But the problem asks to calculate the "maximal" pressure in ampule. Doesn't it mean exactly transient pressure at the moment?

Yes, I consider that all Lithium is converted to T and He, but it is incorrectly to think that we can use Mendeleev-Klapeiron equation in this case. This is simply equation for perfect gas but you must take into account that nuclear reaction gives us huge energy (9,21×105 kJ) and exactly this...

A Lithium-6 sample (m = 12,0 mg) which was isolated in ampule V = 200 cm3,was loaded in nuclear reactor and irradiated by neutrons for a long time. Calculate the maximal pressure in reactor, T = 400 K. The equation is Li + n = T + α I calculated the energy of this reaction using formula...
