Introduction: Alka-Seltzer is a medication used to alleviate ailments such as heartburn and acid indigestion1. The ingredients that the tablet is made up of helps explain the name of the medication, the sodium bicarbonate is used to balance stomach acid, help spread the aspirin which allows the speed of absorption to increase, and reacts with citric sodium which produces carbon dioxide2. One initial observation of the Alka-Seltzer tablet and water is that when the tablet was dropped into the…

Rare earths are very significant when it comes to the development and use of technical equipment as they can be very important to the performance of the unit. An example of an everyday piece of technology that uses rare earths is the IPhone. Apple has said that the IPhone uses eight rare earths, from everything from the colored screen, to speakers, to the miniature circuits inside the phone. Although the amount of rare earths in the phone is very little, the demand for rare earths will continue…

The question my group tried to answer was “Which protein solution contained protein, starch, and sugar, and if so how much?” The protein supplements we had were supplments 4 (Kroger Whey & Soy Protein- Vanilla),6 (Vega Protein and Greens) ,and 8 (Pure Protein Natural Whey Protein). We also had 3 reagents (Biuret’s, Lugol’s ,and Benedict’s). We had two different experiments, the first experiment was to get qualitative data. The second was to get quantitative date. The first experiment we tested…

4-5 SCIENCE 2015-2016 Science Units The fourth- and fifth-grade social studies theme of explorers and colonial America naturally lends itself to an in depth study of oceans and marine life. The year’s themes include: SALTWATER ECOLOGY THE HUMAN BODY ELECTRONICS AND ROBOTICS The children begin the year by studying plants and animals of the Long Island Sound through several field trips to Cove Island Park, where the students become immersed in the various habitats it provides. They work with…

Cassamajor, Kimberly P1 R1 S4 Science Fair Research Paper Honors Chemistry Group Number 8 Research Paper The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the…

charged electrons. Here, the electrons represents the plume in the pudding of positive charge. Hence his model was known as plum pudding model. It was also known as watermelon model where the positive charge was the flesh of the watermelon and the electrons were the sects. a) J.J. Thomson who discovered the electron in 1897, proposed the plum pudding model of the atom in 1904 before the discovery of the atomic nucleus in order to include the electron in the atomic model. b) In Thomson’s model,…

• What are the strategic choices available? Biocon India Group is a Bangalore-based organization that began in 1978 with the enzyme business. An enzyme, by the way, is a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction. That said, the Biocon India realized that growth is imminent and various strategic choices are available. The first strategic choice available to Managing Director, Kiran Mazumdar-Shaw’s Biocon India is expansion…

Paragraph 1 For α-Quartz, its lattice symmetry is trigonal, and for β-Quartz, its lattice symmetry is hexagonal. For α-FePO4, its space group is P3121 and thus its lattice symmetry can be inferred to be also trigonal, just like α-Quartz. Similarly, β-FePO4 space group is P6422 and its lattice symmetry can be inferred to be hexagonal, just like β-Quartz. Although the chemical structures of quartz and FePO4 are different, with quartz having a formula of SiO2, they can actually be in the same…

Introduction: Solubility is the “ability for a given substance, the solute, to dissolve in a solvent” . The effect of temperature on solubility is that when heat (energy) is added, it increases the speed on which molecules and particles move, therefore making it a quicker process. Where as with cooler temperatures there aren’t as many particles because the solvent doesn’t contain as much energy as warmer temperatures, therefore not dissolving as well as it could if it was warmer. To make jelly…

Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…
