chemistry was the worst subject back then

It sounds to me as if you are interested or concerned about the decomposition of sulfur-containing amino acid during hydrolysis.  Is that correct?  If so, what have you learned so far?

I'm curious how these substances would be categorised..

Graphite - molecular?

Graphene - network solid?

Diamond - network solid?

C60 - molecular?

network solid being a macro-molecule

molecular being composed of molecules

network solid and molecular are mutually exclusive I think.. Is that right?

Graphene is a sheet of carbon bonded covalently..  That's a network solid (so, a macromolecule).

Graphite consists of sheets of Graphene, and the sheets are not bonded together covalently. So you have covalently bonded entities, connected together with ("intermolecular") - VDW forces..

With C60 it's molecular because one formula unit is a molecule but there'd be lots of C60 formula units.. each connected together with VDW forces.

Diamond is a network solid because it's all the atoms are in one group bonded covalently.  (not like with Graphite).  So it's a macromolecule. Like Graphene.

So do you agree with those categorisations?

Graphite as molecular?

Graphene as network solid?

Diamond as network solid?

C60 as molecular?

I understand that all of them consist of carbon and carbon only..  Graphite Graphene and Diamond having the same formula (C), but    buckminsterfullerene  having formula C60.  All allotropes of Carbon?

Thanks

This value is 90% , calculate how much is 100%. The difference is the mass of Vitamin C.

If I have a fluid oz of water and I wanted it to have a potency of 10% vitamin C but my vitamin C was in powder form how would I figure out how much powder to add (I’m sorry if this ain’t the place to ask such questions
