Question

Сделать ОВР H2S+H2SO4=SO2+S=H2O Zn+HNO3=N2+Zn(NO3)2+H2O AL+BaCO3=BaO+C+AL2O3 AL+H2SO4=S+AL2(SO4)3+H2O HNO3+HI (Йод)=HI(Йод)O+NO2+H2o

Answer 1

Думаю, так:

H2S(-2) + H2S(+6)O4 = 2H2O + S(+4)O2 + s(0)

S(-2) - 2e = S(0) окисление/восстановитель

S(+6) + 2e = S(+4) восстановление/окислитель 

5Zn + 12HNO3 = 5Zn(NO3)2 + N2 + 6H2O

Zn - 2e = Zn(+2) восстановитель окисляется 

2N(+5) + 10e = N2(0) окислитель восстанавливается 

2Al+ 3H2SO4 = Al2(SO4)3 + 3H2

Al0 - 3е = Al+3   окисляется, восстановитель

2H+  + 2е = 2H0    восстанавливается, окислитель

HI + 6HNO3 = HIO3 + 6NO2 + 3H2O

I(-1) - 6e = I окисление, восстановитель
N(+5) + 1e = N восстановление, окислитель

Balanced Chemical Equations:

1. H2S + H2SO4 = SO2 + S + H2O - The balanced equation for the reaction between hydrogen sulfide (H2S) and sulfuric acid (H2SO4) is: H2S + H2SO4 = SO2 + S + H2O.

2. Zn + HNO3 = N2 + Zn(NO3)2 + H2O - The balanced equation for the reaction between zinc (Zn) and nitric acid (HNO3) is: Zn + HNO3 = N2 + Zn(NO3)2 + H2O.

3. Al + BaCO3 = BaO + C + Al2O3 + Al + H2SO4 = S + Al2(SO4)3 + H2O - The balanced equation for the reaction between aluminum (Al) and barium carbonate (BaCO3) is: Al + BaCO3 = BaO + C + Al2O3. - The balanced equation for the reaction between aluminum (Al) and sulfuric acid (H2SO4) is: Al + H2SO4 = S + Al2(SO4)3 + H2O [[4]](https://pnu.edu.ru/media/filer_public/1e/03/1e032ed6-4aa9-4dd5-8fa4-2502baef0caa/panasuk_mnogovar_zadachi.pdf).

4. HNO3 + HI (Iodine) = HI (Iodine)O + NO2 + H2O - The balanced equation for the reaction between nitric acid (HNO3) and hydrogen iodide (HI) is: HNO3 + HI = HI2O + NO2 + H2O.

Note: Please make sure to double-check the balanced equations and consult reliable sources for further verification.
