thats very nice lol, things stuck in amber are very cool
The formula for the molecular formula is molar mass/ empirical formula
So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 + 7. Then use the molecular formula = 86 / (12*3+7) = 2
Therefore, the molecular formula is 2 times the empirical formula which is C6H14.
Based on our knowledge of strong and weak acids, we can confirm that the Ka value for acetic acid will be relatively low since it is a weak acid.
Acids can be strong or weak. This is determined by its <u><em>tendency to break apart into ions or stay together to form molecules.</em></u> Although somewhat counter-intuitive, strong acids are those that are most likely to break apart and therefore contain a <em><u>high number of </u></em><em><u>ions </u></em><em><u>within their solutions</u></em>.
Weak acids, on the other hand, are those that<em><u> tend to stay together in the form of </u></em><em><u>molecules </u></em><em><u>and therefore possess very </u></em><em><u>low ion counts </u></em><em><u>in their solutions.</u></em> The acid dissociation constant, Kₐ, is used to measure whether an acid is weak or strong and how much so. In the case of Acetic acid, the ka measurement will offer a low value, indicating a weak acid.

Answer:
A inhibitor structure resembles substrate structure B inhibitor binds non covalently at site other than active site.C inhibitors bind covalently and permanently at active site.
Explanation:
A Reversible competitive inhibitors structurally resembles the substrate and competes with the substrate to bind to the active site of the target enzyme.
B Reversible noncompetitive inhibitors binds no covalently at site of the target enzyme that is different from the active site.
C irreversible inhibitors interacts very tightly to the active site of an enzyme by covalent bond which cannot be overcome.
