Question

ionic equations please thank you

2Al(s) + 6H2O(l) → 2Al(OH)3 + 3H2(g)
2Al(s) + 6HCl (aq) → 2AlCl3 (aq) + 3H2(g)
Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g)
2KBr(aq) + Cl2(s) 2KCl + Br2(s or l)
Br2 (s or l) 2 KBr(aq) + I2(s)

Answer 1

2Al(s) + 6H₂O(l) → 2Al(OH)₃(s) + 3H₂(g) ‒ Al(OH)3 doesn’t dissociate to the ions in water solution, that’s why there is no ionic equation for this reaction

2Al(s) + 6HCl(aq) → 2AlCl₃(aq) + 3H₂(g)
2Al(s) + 6H⁺(aq) + 6Cl^-(aq) → 2Al³⁺(aq) + 6Cl^-(aq) + 3H₂(g) ‒ full ionic equation
2Al(s) + 6H⁺(aq) → 2Al³⁺(aq) + 3H₂(g) ‒ net ionic equation

Fe(s) + 2HCl(aq) → FeCl₂(aq) + H₂(g)
Fe(s) + 2H⁺(aq) + 2Cl^-(aq) → Fe²⁺(aq) + 2Cl^-(aq) + H₂(g) ‒ full ionic equation
Fe(s) + 2H⁺(aq) → Fe²⁺(aq) + H₂(g) ‒ net ionic equation

2KBr(aq) + Cl₂(g) → 2KCl(aq) + Br₂(g)
2K⁺(aq) + 2Br^-(aq) + Cl₂(g) → 2K⁺(aq) + 2Cl^-(aq) + Br₂(g) ‒ full ionic equation
2Br^-(aq) + Cl₂(g) → 2Cl^-(aq) + Br₂(g) ‒ net ionic equation

2KI(aq) + Br₂(l) → 2KBr(aq) + I₂(s)
2K⁺(aq) + 2I^-(aq) + Br₂(l) → 2K⁺(aq) + 2Br-(aq) + I₂(s) ‒ full ionic equation
2I-(aq) + Br₂(l) → 2Br^-(aq) + I₂(s) ‒ net ionic equation
