Balance the reaction of Ca + H2O = Ca(OH)2 + H2 using this chemical equation balancer! its not an oxidation reduction as its oxidized - Ca is oxidized by the adding of O which makes it CaO,its not a ppt coz Ca is solid in state but if ur talkin bout Ca being dissolve in water or any solution then it could be a ppt but depends on what solution it is. d.no reaction. Science. The balanced stoichiometric equation is 2 Ca + O2 equals 2 CaO. For instance, iron (very thin wire, as in steel wool) will undergo combustion. O2 having an initial oxidation state of 0 becomes -2 whenever the CaO is produced. It is not a precipitation, though, since one of the reactants is already a solid. So Ca goes from zero on the left to 2+ on the right; therefore, it had to lose two electrons to do that which makes Ca oxidized and O2 is reduced. Similar Questions.
