Introduction Analytical chemistry was used for this project to determine the level of the reaction Fe3+ + SCN- ↔ FeSCN2+. According to ACS Chemistry for Life, “analytical chemistry is the science of obtaining, processing, and communicating information about the composition and structure of matter” (Analytical Chemistry). In this experiment the interaction of iron(III) (Fe3+) and thiocyanate (SCN-) formed, which was processed and now being communicated through the quantitative data collected. Chemical

List and define the six main branches of chemistry ORGANIC CHEMISTRY Organic chemistry involves the study of the structure, properties, and preparation of chemical compounds that consist primarily of carbon and hydrogen. organic chemistry the study of most carbon containing compounds INORGANIC CHEMISTRY Inorganic chemistry is the study of the properties and behaviour of inorganic compounds. It covers all chemical compounds except organic compounds. Inorganic chemists study things such as crystal

INTRODUCTION Osmosis is the “diffusion of water across a selectively permeable membrane” (Raven et al. G-16). In this experiment, dialysis tubing was used to mimic the selectively permeable membrane to show what osmosis does when placed in different solute concentrations. We filled the dialysis tubes with different percentages of solute and placed them in beakers full of another percentage of solute. Through this experiment, I saw what happens when the tube becomes hypertonic, hypotonic, and isotonic

BIODIESEL: A POTENTIAL RENEWABLE FUEL? 1. Introduction. The American philosopher, ecologist and scientist, Aldo Leopold introduced in his book ‘A Sand County Almanac’ in 1949 the idea of ‘thinking like a mountain’. This basic and simple phrase was later analysed and further explored by environmentalist philosopher Arne Naess. He stated that thinking like a mountain consisted mainly in realizing that humans are part of the biosphere, therefore, mankind should be able to recognize several responsibilities

Vent-pipes in cars contain small amount of Platinum-rhodium alloy that transforms toxic emission such as Carbon Monoxide and Nitrogen Dioxide to harmless gas such as Carbon Dioxide. During that process, Catalyst plays an important role in accelerating the gas transformation, in which lowers the activation energy. As an important element in the chemical reaction, catalysts are required in different types of chemical reactions to increase the speed for reaction. During the process of speeding up reaction

Chemical formulas are used to show how new compounds are formed by chemical reactions. In order to learn how chemical formulas are written, we must first learn to understand the different symbols used to identify compounds that are formed.

To define Stoichiometry, it is “the calculation of the quantities of chemical elements or compounds involved in chemical reactions.” Excess Reagent and Limiting Reagent are key terminology that will be crucial to understand for this experiment. Excess Reagent are “reactants that are not used up when the reaction is finished” Limiting Reagent is “the reagent that is completely used up or reacted because its quantity limit the amount of products formed.” There are two types of filtration processes

The Effect of Gibberellic Acid on the Germination of Seeds Authors Bijin Johnson, Veronica Razon, Harmony Juanta, Charlee Parr and Cathleen Castro. Introduction In this practical, six bags containing twelve histrix cactus seeds each were taken and another six bags containing twelve rocket salad seeds in each bag. Each bag was experimented with different concentrations of gibberellic acid to see how fast each would grow. Gibberellic Acid is an organic molecule whose chemical formula is C₁₉H₂₂O₆

An Introduction to Chemiluminescence Chemiluminescence is the is the production of light without heat from a chemical reaction. In this reaction, energy is released as electromagnetic radiation in the visible light spectrum. It does not require the absorption of electromagnetic energy to excite molecules into a higher energy state. Instead, the energetics of the reaction itself releases energy as light. This means that there there is an intermediate molecule in an excited state which returns to
