WebPhosphine is a colorless, flammable, and toxic gas with an odor of garlic or decaying fish. It can ignite spontaneously on contact with air. The gas is shipped as a liquefied, compressed gas. Aluminum phosphide (Celphos, Phostoxin, Quick Phos) and zinc phosphide are solids used as grain fumigants and as a rodenticide, respectively. Zinc phosphide is often mixed … WebApr 2, 2024 · Specific gravity is the ratio of the object's density to the density of water, i.e.: The units cancel out in the ratio. Therefore, the specific gravity is a unitless number. The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit.
WebJan 1, 2024 · Phosphine has the trigonal pyramidal geometry ( Forsyth, Rankin, & Robertson, 1990; Hansen & Bartell, 1965) ( Fig. 26.1) and its chemical formula is PH 3.
