Scientific laws are universal.
The hallmark of ideal physical laws is that they would apply everywhere, all the time, under all circumstances, and some laws of physics come close. The laws of chemistry, being properties of materials, cannot meet that stringent criterion. For example, the chemical equation telling how hydrogen and oxygen combine to form water is correct for most terrestrial circumstances, but becomes utterly meaningless inside the sun, where the temperature is high enough to dissociate water molecules, or indeed to strip the electrons from atoms. The Nobel Prize in Chemistry was given in 1995 to Sherwood and Molina for showing the chemical equations that describe the destruction of ozone by chlorine in a sort of catalytic cycle. The ozone doomsayers take the Sherwood-Molina equations as if they are written in a stone slab.
