Question

1) lead + water

Note: lead will be lead(II) if there is a reaction

a) Pb(s) + H₂O(l) ⟶⟶ No Reaction

b) Pb(s) + H₂O(l) ⟶⟶ PbOH(aq) + H₂(g)

c) Pb(s) + H₂O(l) ⟶⟶ Pb(OH)₂(aq) + H₂(g)

d) Pb(s) + 2 H₂O(l) ⟶⟶ Pb(OH)₂(aq) + H₂(g)

2) barium + water

a) Ba(s) + 2 H₂O(l) ⟶⟶ H₂(g) + Ba(OH)₂(aq)

b) Ba(s) + H₂O(aq) ⟶⟶ H₂(g) + Ba(OH)₂(aq)

c) 2 Ba(s) + 2 H₂O(l) ⟶⟶ H₂(g) + Ba₂OH(aq)

d) 2 Ba(s) + H₂O(l) ⟶⟶ H₂(g) + Ba₂OH(aq)

e) Ba(s) + H₂O(l) ⟶⟶ No Reaction
