Question

Составьте молекулярные и краткие ионные уравнения : Al2O3 + 6HCl = KOH + HCl = Fe(OH)3 + HCl = Ag2O + HCl =

Answer 1

1) Al2O3 + 6HCl = 2AlCl3 + 3H2O
Al2O3 + 6H(+) + 6Cl(-) = 2Al(3+) + 6Cl(-) + 3H2O
Al2O3 + 6H(+) = 2Al(3+) + 3H2O
2) KOH + HCl = KCl + H2O
K(+) + OH(-) + H(+) + Cl(-) = K(+) + Cl(-) + H2O
OH(-) + H(+) = H2O
3) Fe(OH)3 + 3HCl = FeCl3 + 3H2O
Fe(OH)3 + 3H(+) + 3Cl(-) = Fe(3+) + 3Cl(-) + 3H2O
Fe(OH)3 + 3H(+) = Fe(3+) + 3H2O
4) Ag2O + 2HCl = 2AgCl + H2O
Ag2O + 2H(+) + 2Cl(-) = 2AgCl + H2O

Answer 2

Molecular equation: Al2O3 + 6HCl = 2AlCl3 + 3H2O KOH + HCl = KCl + H2O Fe(OH)3 + 3HCl = FeCl3 + 3H2O Ag2O + 2HCl = 2AgCl + H2O

Ionic equation: Al2O3 + 6H+ + 6Cl- = 2Al3+ + 6Cl- + 3H2O K+ + OH- + H+ + Cl- = K+ + Cl- + H2O Fe3+ + 3OH- + 3H+ + 3Cl- = Fe3+ + 3Cl- + 3H2O 2Ag+ + O2- + 2H+ + 2Cl- = 2Ag+ + 2Cl- + H2O
