over heated iron wool.If the total pressure is 866 mmHg, calculate the partial pressures of N2 and H2.
How do u solve this equation, can u plz explain on wht to do with these type of equations. n also if u can show fully how u got ur answer so i know how to do it . thanks in advance

2NH3->N2+3H2
Ptotal=pH2+pN2
as pV=nRT
p is directly proportional to the amount of moles!
so 3 mol of Hydrogen and 1 mol of nitrogen resulted
divide Ptotal by 4
and then 1/4 => pN2
and 3/4=>pH2
866mmHg/4=216.5mmHg=pN2
216.5*3=649.5mmHg =pH2

2NH3 = N2 + 3H2
So if the ammonia is fully decomposed to nitrogen & hydrogen, then there is 4 molar ratios of product gas. One molar ratio of nitrogen and 3 molar ratios of hydrogen.
pN2 : pH2 :: 866/4 : 866 x 3 / 4
pN2 : pH2 :: 216.5 mmHg : 649.5 mmHg

2 NH3 >> N2 + 3H2
we have 1 mole of N2 and 3 moles of H2 => total = 4
n1 / nt = p1 / pt
1 / 4 = p1 / 866
p1 = partial pressure N2 = 216.5 mmHg
n2 / nt = p2 / pt
3 / 4 = p2 / 866
p2 = partial pressure H2 = 649.5 mm Hg

ok i'm going to easily enable you realize what you need to do those properly you will desire to apply (P_i)(V_i)/(T_f)=(P_f)(V_f)/(T_i) the place P is rigidity, V is quantity, T is temperature in Kalvin ( °C + 273) and cancel out any variables that are consistent (or not pronounced in problem), _ shows subscript, i indicated preliminary, and f shows very final. different element you need to renowned is PV=nRT, the place P, V, and T are same as in the previous, n is form of moles, and R is gasoline regulation consistent it is .082 if P is in atm or sixty two.4 if P is in torr/mmHg. For the partial rigidity it is like dilution, in case you do not understand what I advise for this or any of what I wrote remark and that i'll edit answer. sturdy success fixing and enable me understand in case you nonetheless want help.
