Question #56276
Would these equations be correct and are the states correct
4Al(s) + 3O2(g) 2Al2O3(s)
2 Al + 6 H2O → 2 Al(OH)3 + 3 H2
2Al(s) + 6HCl (aq) → 2AlCl3 (aq) + 3H2(g)
Ca (s) + 2HCl (aq) CaCl2 (aq) + H2 (g)
2Mg(s) + O2(g) 2MgO(s)
Mg(s) + 2H20(g) Mg(OH)2(aq) + H2(g)
2Li (s) + 2H2O (l) 2LiOH (aq) +H2 (g)
