AQA GCSE Chemistry Unit 1 C 1: Fundamental ideas: C 1.1. Atoms‚ elements and compounds: * All substances are made up of atoms. * Elements contain only one atom. * Compounds contain more than one atom. * An atom has a tiny nucleus in its centre‚ surrounded by electrons. C 1.2. Atomic structure: * Atoms are made up of protons‚ neutrons and electrons. * Protons and electrons have equal and opposite electrical charges. Protons are positively charged‚ and electrons are negatively

APPLICATIONS OF ORGANIC COMPOUNDS IN LASER TECHNOLOGY WHAT IS AN ORGANIC COMPOUND? An organic compound is any member of a large class of gaseous‚ liquid‚ or solid chemical compounds whose molecules contain carbon. Organic chemistry is the science concerned with all aspects of organic compounds. Organic synthesis is the methodology of their preparation. APPLICATIONS OF ORGANIC COMPOUNDS clothing of cotton‚ wool‚ silk‚ and synthetic fibres; common fuels‚ such as wood‚ coal‚ petroleum‚ and natural

for a 25 000 kilogram order of the private brand compound. While the chemical composition of the Taylor compound differs from that of Fertikil‚ the manufacturing process is very similar. The Taylor compound would be produced in 1000 kilogram batches. Each batch would require 60 direct labor hours and the following chemicals: The first three chemicals (CW-3‚ JX-6‚ MZ-8) are all used in the production of Fertikil. BE-7 was used in a compound that Swift has discontinued. This chemical was not

chemistry. In organic chemistry‚ we all have different kinds of compounds. In addition‚ alkanes‚ alkenes‚ and alkynes are the parts of the organic and inorganic compounds. We also can learn about the structural formula they all have in different form. Polymerization is another type of chemical reaction that we get to know. There is also a difference between the saturated and unsaturated compounds. All distinguish particular compounds have all kind of formula‚ structural form‚ and many other ways to

Based on the spectra generated by C5H12O‚ the identity of the compound was 2-pentanol. The first step in identifying the compound was finding the degree of unsaturation. For C5H12O‚ the degree of unsaturation was zero‚ which means that the compound only has single bonds. Knowing that there were only single bonds led to the assumption that the O in the compound was either an alcohol or an ether. The IR spectrum helped in determining which functional group was present. The peak that determined the

analysis of organic compounds determine the elements present in them but they do not give the actual structure or the functional groups present. Since all organic compounds contain hydrogen and carbon‚ most tests consist of only the determination of oxygen‚ sulfur‚ nitrogen and halogens – elements that are most of the time the only ones involved in organic compounds. The experiment focused on the Sodium Fusion test‚ which tested for all elements except oxygen. In the test‚ the test compound is broken down

evidence that contains inorganic compounds. Paint tends to be inorganic in nature. The white‚ red‚ yellow pigments of paint is inorganic by nature. Organic compounds are based on carbon these are found only on living things. Inorganic is the opposite it doesnt come from living things its from synthetic fibers like polyester or nylon are carbon based but are not found in plants or animals. From a forensics science point of view both inorganic and organic compounds are very important when found

applying heat). During column chromatography‚ a solution is passed through a filtration system of silica‚ sand‚ and cotton. This creates colored or colorless bands‚ dependent on the type of chemical compound‚ and is comparable to a reverse TLC test. The differences in polarity pull down the compounds at different rates‚ allowing for the separation. Experimental: Dry‚ sublimed ferrocene (93 mg) was added to a reaction tube.

chemistry came from the word organism. Prior to 1828‚ all organic compounds had been obtained from organisms or their remains. The scientific philosophy back then was that the synthesis of organic compounds could only be produced within living matter while inorganic compounds were synthesized from non-living matter. A theory known as "Vitalism" stated that a "vital force" from living organisms was necessary to make an organic compound. 1828‚ a German chemist Friedrich
