Inorganic compound

the prefix "stereo-" signifies "three-dimensionality". The primary investigation of stereochemistry is on stereoisomers and traverses the whole range of natural, inorganic, organic, physical and particularly supramolecular science. Stereoisomers are isomeric molecules that have the same sub-atomic recipe and arrangement…

and carries upward with the fracked gas ‘produced waters’ containing radioactive materials, heavy metals, hydrocarbons such as BTEX (benzene, toluene, ethylbenzene, and toluene), bromide, highly concentrated salts, and many other organic and inorganic compounds that, when exposed to our environment, are dangerous health hazards--many are known carcinogens and toxic to biological life,” (Carluccio). When these toxins get into a humans system the effects can be deadly. BTEX, can cause harmful…

In August 1945, the most horrific events occurred in Hiroshima and Nagasaki: the dropping of the atomic bombs. The whole creation of this highly destructive item began in 1939 with the splitting of a uranium atom. Scientists believed that the energy harvested could be useful to making such powerful weapons. The Manhattan Project was a code name given in 1941 for the devising of the atomic bomb. At one point, there were over 120,000 Americans that were employed in this project, and almost two…

radioactive carbon atoms. Scientists anticipated that if there were life-forms, they would use up the nutrients and in response, release carbon dioxide or methane gas. The LR was equipped with a radiation detector to identify any of these chemical compounds. To limit the chance of outlying factors, several controlled experiments were designed. The rovers treated some samples with fluctuating heat and some with different exposure to light, leaving some samples in the dark for several months. In…

Oxyanions are anions which contain oxygen. Part 5. Determination of % of Fe (II) in a salt redox titration. A titration is a quantitative analysis. From a titration the concentration of a given sample, in this case Fe(II) can be found by using a standard compound of whose concentration is known, in this example: 0.02M of KMnO4. A redox titration involves an oxidation-reduction reaction, hence the name redox. Redox reactions involve the transfer of electrons, i.e. the loss and gain of electrons.…

point. In the treatment of water for Brisbane, the water is first filtered, and then ammonia and chlorine (in the form of hypochlorous acid, HOCl) are added to form chloramine, which kills any remaining bacteria and viruses. Chloramine (NH2Cl) is a compound made from chlorine and ammonia.The concentration of chloramine is maintained in the water to ensure bacteria do not re-grow in the distribution system. HOCl + NH3 → NH2Cl + H2O. These substances, while safeguarding the water, may cause a…

CHAPTER 1 TIN OXIDE 1.1 Introduction Tin dioxide, also known by the systematic name tin(IV) oxide and stannic oxide in the older notation, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is the most important raw material in tin chemistry. This colorless, diamagnetic solid is amphoteric. 1.2 Structure It crystallises with the rutile structure, wherein the tin atoms are six…

organisms are made of cells and their products. • New cells are created by old cells dividing into two. • Cells are the basic building units of life. The development of the microscope was vital for all 3 points. Without the invention and founding of compound microscopes and electron microscopes as well as new stains and techniques to look at specimens discoveries such as ʻnew cells are created by old cells dividing into twoʼ would not have…

Silver nanoparticles have unique antimicrobial properties. They have a variety of applications: diagnostics, wound healing, pharmaceuticals, etc. These nanoparticles destroy bacterial cells walls and interrupt membrane integrity by their electrostatic attraction to the negatively charged bacterial cell walls [10]. Metal nanoparticles are usually synthesized by chemical techniques which is costly and highly toxic. Currently, there is a growing demand for alternative methods that would limit the…

•Background and aim Soil salinity is one of the major environmental obstacles that limit the crop productivity. A pot experiment was conducted with an aim to explore the ameliorative effects of exogenously applied sodium nitroprusside (SNP) concentration against salinity stress in Brassica napus (L.) cv. Pactole. Methods Plants were grown under greenhouse conditions in plastic pots and were exposed to ***** mM NaCl. Further, ***** days old plants were sprayed with sodium nitroprusside (SNP,…
