Know These Gases
You all learned to count to ten. Well most of you. Lets add some other gases that you just need to know. Some we have gone over and I am adding a few.
C2H2 is Acetylene or you see me draw it as a C with three dashes. It's a triple bond hydrocarbon. Oh and it's super mad about being one. So he has a tendancy to want to explode.

CO carbon monoxide
CO2 carbon dioxide

IC4 isobutane
NC4 normal butane

C2= ethylene
C3= propylene​​​​​​​​​​

H2S hydrogen sulfide & when you burn it you get
SO2 sulfur dioxide​​​

He helium
H2 hydrogen​​​
