- How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love - Albert Enstein
- Chemistry is like cooking (Just don´t lick the spoon) -
Matter: anything that take up space and has a mass
Trace elements: elements that are required by an organism in only minute quantities.
Hydrogen bonds: the attractions between water molecules.
Isomer: molecules that have the same molecular formula but differ in their arrangement of these atoms.
