София · Answer 1

2AL+3O2=2Al2O3

Al2O3 + 6HCl = 2AlCl3 + 3H2O

AlCl3 + 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
