18
Q

monosaccharide

A

a sugar that has a ring structure in water

19

20
Q

vitalism

A

the theory that the origin and phenomena of life are dependent on a force or principle distinct from purely chemical or physical forces

21
Q

falsification of vitalism

A

urea crystal was produced in a lab which proved vitalism false

22
Q

what was wohler trying to produce in the process of accidental falsification

A

ammonium cyanate

23
Q

catalyst

A
