Wyckoff was formed as a township by an act of the New Jersey Legislature on November 2, 1926, replacing Franklin Township, based on the results of a referendum held that day. Portions of Wyckoff were ceded to Midland Park based on the results of a referendum held on June 9, 1931.
The IV in lead IV oxide means that the lead ion has a 4+ charge. The oxide ion has a 2- charge. The charges must cancel out to zero, so there are 2 oxide ions for every 1 lead â¦ IV ion, which is what the formula PbO2 shows.
Solid V 2 O 5 is reduced by oxalic acid, carbon monoxide, and sulfur dioxide to give vanadium(IV) oxide, VO 2 as a deep-blue solid. Further reduction using hydrogen or excess CO can lead to complex mixtures of oxides such as V 4 O 7 and V 5 O 9 before black V 2 O 3 is reached.
