Ionic equations for the following
4Li(s) + O2(g) → 2Li2O(s)
2Li (s) + 2H2O (l) 2LiOH (aq) +H2 (g)
Ca(s) + 2H20(g) Ca(OH)2(aq) + H2(g)
2Ca(s) + O2 (g) 2CaO (s)
4Al(s) + 3O2(g) → 2Al2O3(s)

4Li(s) + O2(g) → 2Li2O(s)
2Li (s) + 2H2O (l) → 2Li+(aq) + 2OH-(aq) + H2(g)
Ca(s) + 2H2O(l) → Ca2+(aq) + 2OH-(aq) + H2(g) *Usually Ca(OH)2 is almost insoluble in water, so another way is to assume that it's a solid, then the net ionic equation would be different: Ca(s) + 2H2O(l) → Ca(OH)2(s) + H2(g)
