Ionic equations for the following thank you for your help
4Li(s) + O2(g) → 2Li2O(s)
4Na(s) + O2(g) → 2Na2O(s)
2Ca(s) + O2 (g) 2CaO (s)
Ca (s) + 2HCl (aq) CaCl2 (aq) + H2 (g)
4Al(s) + 3O2(g) → 2Al2O3(s)
2Al(s) + 6H2O(l) → 2Al(OH)3 + 3H2(g)

4Li(s) + O2(g) → 2Li2O(s) ‒ all substances in this reaction do not dissociate to the ions in water solution, that’s why there is no ionic equation for this reaction
4Na(s) + O2(g) → 2Na2O(s) ‒ no ionic equation for this reaction
2Ca(s) + O2(g) → 2CaO(s) ‒ no ionic equation for this reaction
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
