Question

2 things in the universe that doesn't contain chemistry/

Answer 1

Space and Vacuum

Well, Space itself can be defined as co-ordinates of specific region from the origin (Earth), acting as boundary around that co-ordinate (an massless container) .

Absence of an object or a particle in that co-ordinate will create an Empty space called vacuum

They both are in the universe and do not contain chemistry (do not take up space and have no mass)
