GASES 7. Organic Chemistry: concerns with structures and reactions of organic compounds. Analytical Chemistry: concerns with the determination of chemical compounds, their quantities Physical Chemistry: investigation of the effects of various physical parameters temperature, pressure, concentration, etc. Proteins, nucleic acids are biopolymers composed of organic molecules. Bioanalytical chemistry Bioinorganic chemistry. Bioorganic chemistry Theoretical chemistry: without any experimentation, based on calculations Chemical Engineering: processes and operations in industrial scale, design for chemical tecnologies. Biotechnology: progress related with biochemistry, biology, medicine pharmacy; production of pharmaceuticals, gene therapy, industrial scale production of pharmaceuticals. The quantity of matter is measured by its mass. The characteristics that we can use to identify samples of matter and distinguish them from one another are called properties. Extensive properties capacity properties : depend on quantity of matter: mass, volume Intensive. Chemical properties: paper burns, iron rusts, wood rots. In each case the object changes not only in physical apparence but also in its basic composition. In a chemical change, a sample of matter is transformed into completely different materials. Element: a substance comprised of just a single type of atom. Elements cannot be decomposed into simpler substances, not by heating, crushing, exposure to acids. H, O, F,C, Cl Compound: Atoms of different elements can combine with one another to form more complex substances called chemical compounds. H2O, SO2. Matter is conserved during chemical reactions. According to this law, mass balance can be written for every chemical reaction. Each chemical element is composed of minute, indestructible particles called atoms. Atoms can be neither created nor destroyed during a chemical change. All atoms of an element are alike in mass and other properties, but the atoms of one element are different from those of all other elemnents. In chemical Rudolf Clausius Cosmic Casino, atoms of different elements combine in simple numerical ratios: for Rudolf Clausius Cosmic Casino, one atom of A to one of B ABone atom of A to two of B AB2. John Dalton. Dalton modern kimyann en nemli kurucularndan biri. Madde iin atom kuramn nermitir. Dalton Kuram ktlenin korunumu ve sabit oranlar yasalarna ve Dier gzlemlere dayanlarak nerilmitir.

Dalton Dalton atom theory chemistry laws. Faraday: ran an important series of experiments on chemical electrolysis. In the experiments, compounds are decomposed by electricity. He studied the relationship between the amount of electricity used and the amount of compound decomposed. Stoney : proposed that units of electrical charge are associated with atoms. Then, he suggested that these units be called Further information on electrons at the end of 19th century using Cathode-Ray tubes. Attempts to pass an electric current through a vacuum led to the discovery of cathode rays. Two electrodes are sealed in a glass tube from which air is completely removed.
Application of the law to the entire universe, first proposed in the s, led to the prediction of a future 'heat death', where all life has ceased and all organization dissolved.
