Question

Calculati compozitia procentuala a HCL si H₂SO₄.

Answer 1

HCl+H2SO4=Cl2+H2O+SO2

Answer 2

MHCl=AH+ACl=1+35,5=36,5 g HCl                                                                     36,5gHcl...1gH....35,5gCl  
100gHCl....x g H....y g Cl
x=100/36,5=2,73 %H
y=100*35,5/36,5=97,26% Cl

MH2SO4=2AH+AS+4AO=2+32+64=98 g H2SO4 
98gH2SO4...2gH...32gS...64gO
100gH2SO4...x g H...y g S....z g O
x=100*2/98=2,04 g H
y=100*32/98=32,65 g S
z=100*64/98=65,30 g O
