Question

Va rooooooooooooog!!!!!!!

Answer 1

I

mCu impur = 1600kg

p = 80%

mH2SO4 = ?

mCuSO4 = ?

mgaz = ?, Vgaz = ?

II

p=mp*100/mimp => mp = p*mimp/100 = 80*1600/100 = 1280kg Cu pur

III

Cu + 2H2SO4 => CuSO4 + SO2 + 2H2O

Reactanti: Cu si H2SO4

Produsi de reactie: CuSO4, SO2 (se degaja), H2O

IV

MCu = 64

MH2SO4 = 98

MCuSO4 = 160

MSO2 = 64

MH2O = 18

V

1280kg.....x................y..............z

Cu + 2H2SO4 => CuSO4 + SO2 + 2H2O

64kg........2*98kg......160kg......64kg

x = 1280*2*98/64 = 3920kg H2SO4 => mH2SO4 = 3920kg

y = 1280*160/64 = 3200kg CuSO4 => mCuSO4 = 3200kg

z = 1280*64/64 = 1280kg SO2 => mgaz = 1280kg SO2

nSO2 = m/M = 1280000/64 = 20000 moli SO2

Vgaz = nSO2*Vm = 20000*22,4 = 448000 L = 448 kL
