Химия: 1)al-al2o3-alcl3-al(oh)3-al2(so4)3 | naalo2 2)nacl-hcl-h2-h2s-so2-so3-h2so4-h2s | cl2-i2

amina327 · Answer

2AL+3O2=2Al2O3Al2O3 + 6HCl = 2AlCl3 + 3H2OAlCl3 + 3NaOH = Al(OH)3 + 3NaCl Al2(SO4)3+6NaOH = 2Al(OH)3+3NaSO4 Na2SO4 + Al2(SO4)3 + H2O = 2 NaAlO2 + 4 H2SO4 NaCl + H2SO  = NaHSO4 + HCl  2HCl + Mg = MgCl2 + H2 H2 + S  = H2S 2H2S + 3O2 = 2H2O + 2SO2 2SO2 + O2 = 2SO3 SO3 + H2O = H2SO4 2H2SO4 + 2S = 3SO2 + 2H2O 4Mg + 5H2SO4 = 4MgSO4 + H2S↑ + 4H2O    ...
