The latter gas remains in the eudiometer, together with the50 volumes of oxygen that were employed in excess. From this analysis it is seen that two volumes of ammoniacontain three volumes of hydrogen and one volume of nitrogen,a composition which is expressed by the formula Nff. Chemical Properties.—Ammonia gas is decomposed by ahigh temperature, as by a series of electric sparks. The experi-ment may be made by passing the gas through a porcelain tube
