It's an element. Ordinary methods of breaking down chemicals, like catalysts and enzymes, can only get a contaminant down to its constituent elements - if you want to break down carbon monoxide, for instance, you'd wind up with a pile of carbon and some oxygen which would go off into the air as all gases do. Chlorine's already an element so you can't go any farther.
CFC's are unstable. they break down to deplete ozone.
babies with PKU cannot break down phenylalanine
No. Helium is inert; it will not break down or combine with other substances. Since it is an element, it cannot be broken down by chemical means.
chlorine and bromine
Cellulose. It is so tough even we humans cannot break it down.
CFC's are unstable. they break down to deplete ozone.
They break down ozone into oxygen atoms.

It cannot Break down Urea
Yes, it can broken down into two elements: copper & chlorine
Do you mean elemental chlorine, or the "chlorine" that's used in swimming pools?Sunlight can break down swimming pool "chlorine". For that matter, it can break down elemental chlorine also, into two chlorine free radicals, which are much more reactive than elemental chlorine (which is, itself, kinda reactive). Sunlight can cause a mixture of elemental chlorine and elemental hydrogen to explode.Free radical chlorine is serious business. It's one of the prime culprits in the degradation of the Earth's ozone layer.
Potassium and Chlorine. Lead and nitrogen were recently proven to not really be elements, because you can break them down into potassium and chlorine. :)
No, 11 is a prime number, you cannot break it into factors.
Humans cannot break down cellulose because it contains beta glucose and the enzymes that humans have cannot break down beta glucose.
No you cannot because it is hard to break down
an element
Urea
