2Al + 6H2O + 6NaOH → 2Na3[Al(OH)6] + 3H2
n(H2)=14.78l/22.4l/mol=0.66mol
n(Al)=n(H2)/3*2=0.66mol/3*2=0.44mol
m(Al)=n(Al)*M(Al)=0.44mol*27g/mol=11.88g
2AI+2H2SO4-->AI2(SO4)3+3H2
Fe+H2SO4-->FeSO4+H2
m(H2SO4)=V*p*w%=806*1,07*0,1=86,2g
n(H2SO4)=m/M=86,2g / 98g/mol=0,889mol
n(AI)=n(H2SO4)=0,44mol
m(H2SO4) реакция с AI=0,44mol*98g/mol=43,12g
m(H2SO4) реакция с Fe=86,2g-43,12g=43g
n(H2SO4)=m/M=43g/98g/mol=0,439mol
n(H2SO4)=n(Fe)=0,439mol
m(Fe)=n*M=0,439*56=24,57g
m(общ AI и Fe)=11,88+24,57=36,45g
w(Fe)=m(вещ)/m(общ) *100%=24,57/36,45*100=67,4%

1.Ba3(PO4)

Ba +2H3PO4 =Ba3(PO4)2 +3H2
Ba(0) +6H+ +2PO4(3-)=Ba3(PO4)2 +3H2
3BaO+2H3PO4 =Ba3(PO4)2 +3H2O
3BaO + 6H+ +2PO4(3-) =Ba3(PO4)2 +3H2O
3Ba(OH)2 + 2H3PO4=Ba3(PO4)2 +6H2O
3Ba+2 +6H+ +2PO4-3 +6Cl- =Ba3(PO4)2 +6H+ +6Cl-
3Ba+2 +2PO4 -3 =Ba3(PO4)2
3BaCl2+2 Na3PO4=Ba3(PO4)2 + 6NaCl
3Ba+2 +6Cl- +6Na+ +2PO4-3=Ba3(PO4)2 +6Na+ +6Cl-
3Ba+2  + 2PO4-3=Ba3(PO4)2
2.NaCl
Na2O  +2HCl =2NaCl +H2O,  Na2O +2H+ +2Cl-=2Na++2Cl- +H2O,  Na2O +2H+=2Na+ =H2O
NaOH +HCl=NaCl +H2O
Na+ +OH- +H+ +Cl-=Na+ +Cl- +H2O,H+ +OH-=H2O

3Ba+2 +6OH- +6H+ 2PO4-3 =Ba3(PO4)2 +6H2O
3BaCl2  +2H3PO4 =Ba3(PO4)2 +6HCl
