Arsine is an inorganic compound with the formula AsH3. This flammable, pyrophoric, and highly toxic gas is one of the simplest compounds of arsenic. Despite its lethality, it finds some applications in the semiconductor industry and for the synthesis of organoarsenic compounds. The term arsine is commonly used to describe a class of organoarsenic compounds of the formula AsH3−xRx, where R = aryl or alkyl. For example, As(C6H5)3, called triphenylarsine, is referred to as "an arsine."
At its standard state, arsine is a colorless, denser-than-air gas that is slightly soluble in water (20% at 20 C) and in many organic solvents as well. Whereas arsine itself is odorless, owing to its oxidation by air it is possible to smell a slight garlic or fish-like scent when the compound is present above 0.5 ppm. This compound is generally regarded as stable, since at room temperature it decomposes only slowly. At temperatures of ca. 230 °C decomposition to arsenic and hydrogen is rapid. Several factors, such as humidity, presence of light and certain catalysts (namely aluminium) facilitate the rate of decomposition.

Maybe we're just getting older
But the songs, they ain't the same
I'm tired of living from day to day
You're still playing them fucking games
I just don't look at things the same
But my mind's growing more every day
In my mind I've started to see things clearer
Now I know who I am when I look in that fuckin mirror
In the mirror
It's too bad we've had to go through so much pain
But that pain, it made me go
That pain, it kept me moving
That pain, it helped me grow
I just don't look at things the same
But my mind's growing more every day
In my mind I've started to see things clearer
Now I know who I am when I look in that fucking mirror
In the mirror
It's too bad we had to go through so much pain
But that pain it made me go
That pain it kept me moving
That pain is what will always help me grow and grow and grow
