C+H2SO4=CO2+SO4+H2O
Ag+HNO3=AgNO3+NO+H2O​

Объяснение:

C + 2H2SO4 = CO2 + 2SO4 + 2H2O

0            +4

C - 4e  = C   окисление     С - восстановитель ║ 1

+6          +4

S  + 2e = S восстановление  H2SO4  - окислитель║ 2

3 Ag  + 6 HNO3 =  3AgNO3  +  3NO  +  3H2O​

0              +1

Ag  -1e  = Ag  окисление  Ag  -  восстановитель ║ 3

+5            +2

N  + 3e  = N  восстановление  HNO3 - окислитель║1
