1 How long does it take for an ear piercing to heal? ...I got a second ear piercing at claireâs about two months ago. 2  I kept the earring on for 6 weeks and cleaned it with the antiseptic like they said to.
For instance, suppose we believe our sample is benzene (C 6 H 6). We can compare the following: 1  The empirical formula (CH) obtained from the molecular formula of benzene (C 6 H 6). 2  The empirical formula obtained from a elemental analysis of the sample.o do this, we need to determine the empirical formula from the molecular formula. To determine the empirical formula of a known substance, such as glucose, we take the subscripts of the molecular formula (C 6 H 12 O 6) and reduce then to the simplest whole number ratios. If we divide this by 6, we get C 1 H 2 O 1.
Below are the pi-orbital diagrams of benzene, the most identifiable aromatic compound. Each of the three double bonds contributes 2 pi-electrons over 6 atoms, for a total of 4*1+2=6 electrons, in a ring, in a pi-orbital that is planar.Therefore it is aromatic. In contrast, hexatriene meets all of these criteria as well, but is not in a closed ring. Hexatriene is therefore non-aromatic.he Huckel aromaticity rules are: 1  Molecule is cyclic. 2  Have one p orbial per atom of the ring. 3  Be planar, in an sp2 hybridized orbital, over every atom of the ring. 4  Have a closed loop of 4n+2 pi-bond electrons, where n is equal to any integer (0,1,2,3,â¦).
