Chemical Properties of Arsenic
Under ordinary conditions of temperature and pressure, arsenic does not coine directly with hydrogen unless the latter is in an activated or nascent condition. Three hydrides are known, however, two of which, hydrogen monarsenide, AsH or As 2 H 2, and the di-arsenide, As 2 H or As 4 H 2, are solid at ordinary temperatures, the third being the gaseous hydride, arsine, AsH 3, which is the most

Physical and Chemical Changes - Chemistry | Socratic
Acting upon matter can cause it to change, but it is useful to separate these changes into two different egories: physical and chemical. A chemical change describes a process that changes one material into another. Burning wood causes it to turn into ash, a different material. A physical change is simply changing the shape or state, such as cutting a piece of wood into two pieces.
