The correct answer among the choices given is option B. The name of the compound GaAs is gallium arsenide. It is a compound of the elements gallium and arsenic. It found an application in the manufacture of devices such as microwave, infrared LED, laser diodes and solar cells.
The abbreviation or formula GaAs refers to the chemical compound gallium arsenide, that as indicated by its name contains gallium, which is a metal, and arsenic, which is a metalloid. This compound is more commonly used as part of the manufacturing processes of multiple devices such as microwaves or computers because this is a semiconducting material, and due to this, it is ideal for creating circuits. According to this, the compound GaAs refers to Gallium arsenide.
The reaction occurs in a similar way as magnesium does, but much less vigorous. Strong heating is required to make iron powder burn in oxygen. The reaction gives out a yellow showery sparks and produces a black solid. iron reacts with dilute hydrocloric acid to give iron chloride and hydrogen gas.
