Р = n/V = m/(MV) = 0.025 г / (331.69 г/моль * 1 л) = 7.54 · 10^-5 моль/л
Ag2CrO4 = 2Ag(+) + CrO4(2-)
[CrO4(2-)] = P = 7.54 · 10^-5 моль/л
[Ag(+)] = 2 [CrO4(2-)] = 1.51 · 10^-4 моль/л
ПР = [Ag(+)]² [CrO4-] = ( 1.51 · 10^-4 ) ² · 7.54 · 10^-5 = 1.71 · 10^ -12
Cl2 + H2 = 2HCl
2HCl + CuCO3 = H2CO3 + CuCl2
2H + 2Cl + CuCO3 = 2H + CO3 + Cu + 2Cl
CuCO3 (в осадке) = CO3 + Cu
CuCl2 + Zn = ZnCl2 + Cu
ZnCl2 + 2AgNO3 = 2AgCl + Zn(NO3)2
Zn + 2Cl + 2Ag + 2NO3 = 2AgCl + Zn + 2NO3
2Cl + 2Ag = 2AgCl (в осадке)
1) 2Al + 6HCl = 2AlCl3 + 3H2
AlCl3 + 3NaOH = Al(OH)3 + 3NaCl
2) 2Al(OH)3 (t)= Al2O3 + 3H2O
3) Al2O3 + 3H2 = 2Al + 3H2O
4) 2Al + 3S = Al2S3
5) Al2S3 + 6HNO3 = 2Al(NO3)3 + 3H2S
2Al(NO3)3 = Al2O3 + 6NO2 + 3O2
Al2O3 + 3H2 = 2Al + 3H2O
6) 2Al + 6HCl = 2AlCl3 + 3H2
2NaOH + N2O5 = 2NaNO3 + H2O
