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.
Benzene is an organic chemical compound sometimes known as benzol. It has a particularly sweet smell and is a colorless, flammable liquid. Benzene is a major industrial solvent and is used in the production process of plastic, oil, synthetic rubber and many dyes.The scientist Michael Faraday discovered benzene in 1825.d. Commonly, benzene is used as an additive to other chemicals. It is used to make styrene, which is used to make plastics and polymers, and in the manufacturing process of nylon. Small amounts are used in the manufacturing processes of drugs, detergents, pesticides and explosives.
