Organic Chemistry

The cold on the surface
no longer penetrates.
How dry can
dry ice be?

I was melted once,
frozen thrice,
wafted away
in disguise.

When I met the one
that completed me,
you said you
wouldn't be able to breathe.

I was named,
a million adverse effects;
most abundant
my lease.

I am aerated.
I am fizz.
Yet no longer
does my carbon cease.

I am compounded,
within so confounded.
Yet, up to no avail
does my dryness ease.
