Fe203+H2SO4=
H2SO4+NaOH=

CuSO4+H2S=

Answer 1

Ответ:

Объяснение:

Pb(OH)2 = H2O + PbO

2Ni(OH)3 → Ni2O3 + 3H2O

SiO2 + 2 NaOH → Na2SiO3 + H2O

Cr2(SO4)3 + 6 NaOH → 2 Cr(OH)3 + 3 Na2SO4

2 NaOH + Co(NO3)2 → 2 NaNO3 + Co(OH)2

2 Al + 6 HCl → 2 AlCl3 + 3 H2

BaO + 2 HNO3 → Ba(NO3)2 + H2O

Fe2O3 + H2SO4 = Fe2(SO4)3 + H2O

2NaOH + H2SO4 → Na2SO4 + 2H2O

H2S + 2NaOH → Na2S + 2H2O

AgNO3 + HCl → AgCl + HNO3

H2S + CuSO4 → CuS + H2SO4
