Its B- a mixture.
Because I don't think you could separate and atom by distillation or filtration.
Actually I don't think you could separate an element by them.
I'm pretty sure compound can't be separated by them either.
I haven't done these in some time, so I'm not sure if they are 100% right.
1) 6.3 moles of H2( 2 mol of NH3 / 3 mol of H2)= 4.2 mol of NH3
6.3 moles of H2( 2 mol of NH3/ 3 mol of H2)(17.04 g of NH3/1 mol NH3)= 71.57 g of NH3
2) 2.5 moles of N2(2 mol of NH3/1 mol of N2)= 5 moles of NH3
2.25 moles of N2(2 mol of NH3/ 1 mol of N2)(6.02x10^23 particles/ 1 mol of NH3)= 3.01x10^24 particles of NH3
3) 425 g of NH3(1 mol of NH3/17.04 g NH3)= 24.9 moles of NH3
425 g of NH3(1 mol of NH3/17.04 g of NH3)(1 mol of N2/2 mol of NH3)(28.02 g of N2/1 mol N2)= 349 g of N2
425 g of NH3(1 mol of NH3/17.04 g of NH3)(1 mol of N2/2 mol of NH3)= 12.5 mol of N2
4) 10 moles NH3(3 moles of H2/2 moles of NH3)= 15 moles H2
10 moles NH3(3 mol of H2/2 mol of NH3)(2.02 g of H2/1 mol of H2)= 30.3 g of H2
30.3 g = .0303 liters of H2
In order to determine if compounds X and Y are the same, the mole percentages of the elements present should be equal in both compounds.
For compound X
number of moles H = 15/ 1 =15 mol H
number of moles O = 120/ 16 = 7.5 mol O
total moles = 22.5 mol
mole percentages
% mole H = 67%
% mole O = 33%
For compound Y
mole of H = 2 /1 = 2
mole of O = 32/16 = 2
total mole = 4 mole
mol %
% mol H = 50%
% mol O = 50%
there the two compounds are not the same.
