3.Long-lasting concentrated, strong taste, good effect with just a little additives. 2) Please use it as soon as possible after opening, if you can not use it out at one time, please keep the left sealed in time from deterioration. It belongs to normal phenomenon and will not affect the flavor of the products.
Feb 25, 2010 · Express your answer as a chemical formula.? Butanedione, a component of butter and body odor, has a cheesy smell. Elemental analysis of butanedione gave the following mass percent composition: C, 55.80%; H, 7.03%; O, 37.17%. It is present in many California chardonnays known as "Butter Bombs," although there is a growing trend back toward the more traditional French styles.; Diacetyl (IUPAC systematic name: butanedione or 2,3-butanedione) is a natural byproduct of fermentation.
Feb 12, 2012 · is 2,3-butanedione an aldehyde or ketone? Answer Save. 2 Answers. Relevance. Anonymous. 8 years ago. Its a ketone. A The empirical formula—Ca 3 (PO 4) 2 —indicates that the simplest electrically neutral unit of calcium phosphate contains three Ca 2+ ions and two PO 4 3− ions. The formula mass of this molecular unit is calculated by adding together the atomic masses of three calcium atoms, two phosphorus atoms, and eight oxygen atoms. The structural formula can be written as e.g. CH 3 CH 3 (ethane), CH 3 CH 2 CH 2 CH 2 CH 3 or CH 3 (CH 2) 3 CH 3 pentane. CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 CH 2 CH 3 or CH 3 (CH 2) 6 CH 3 octane etc.. More on molecular representations in 1.1.2., but the style of molecular representation above would be described as an abbreviated or condensed structural formulae. Apr 10, 2008 · the 2, 3, 1 refers to the carbon chain. 2 and 3 signify that the two chlorines are on the 2nd and 3rd carbon. 1- ....ol means OH on the first carbon. Alcohols take priority when determining which way to go on the chain, so you put the alcohol on the 1 position first, and then 2 and 3 become relative to the alcohol. 2,3-Dimethylpentane is notable for being one of the two simplest alkanes with optical isomerism. The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2.
