text: skelton equation for copper chloride and lead nitride? write a skelton equation with the corrected formula for each chemical in the reaction. this is difficult, as there may be more than one formula for the compounds you listed.  copper (i) chloride is cucl copper (ii) chloride is cucl2 lead nitride is usually used to mean "yellow lead" which is lead (ii) nitride, which is pb3n2; but it could also be used for lead (iv) nitride which is pb3n4.  one possible reaction: pb3n2 + 3 cucl2  -->  cu3n2 + 3 pbcl2  this is a double replacement with no redox.
