Carbon comes in many forms
Hard as diamond, soft as soot
Coal or graphite when we write
And fancy fullerine to boot.
Carbon chains are straight or branched
Or closed to form a ring
Organic compounds these are called
Parts for life they bring.
Coal and oil and fuel gas
Once mined they have much worth
These reservoirs of energy
Were once alive on earth.
When carbon joins with oxygen
It's either two or one
The double causes drinks to fizz
The single one? you're gone.
I mean carbon dioxide's fairly good
Most days it is our friend
But carbon monoxide's something else
One miss can mean the end.
