A chemist must prepare 900.mL of 131μ M aqueous zinc oxalate ZnC2O4 working solution. He'll do this by pouring out some 168μmolL aqueous zinc oxalate stock solution into a graduated cylinder and diluting it with distilled water. Required:
Calculate the volume in of the zinc oxalate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
