Chemical compound

A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The evolution of energy as heat and light, production of gas, formation of a precipitate, and color change are 4 indicators of a chemical reaction. Two out of the six types of reactions are the single and the double replacement reactions. During single replacement, one element replaces another element in a compound. There…

“Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total…

special type of solution involving the chemical Luminol that glows blue in the dark. The topic of this experiment is to determine what other liquids can react with Luminol to make the solution glow blue in the dark. The independent variable would be the types of chemicals used (in cups) and the dependent variable would be duration of blue glow (in seconds). The scientist began by researching the chemical. The scientist found that Luminol, or C8H7N3O2, is a chemical that exhibits…

the effect of the manganese oxide catalyst, a similar compound to Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its placement on the periodic table between Chromium (24) and Manganese (25), it is believed to have a similar atomic and electronic structure to these two elements, and hence similar chemical properties. This means that Chromium or…

You have recently reached out to our firm Nittany Chemical Analysis to assist you in assigning the correct empirical formula for Manganese ( ) Chloride. On the 14th of September 2015, we carried out an experiment and we were able to accurately determine that manganese had an oxidation number of III. From this finding we are confident that the empirical formula for the compound in question is Manganese (III) Chloride. Throughout the entire course of this letter, we will further explain our…

quantity of benzene rings on the compound. The rotational direction of the phenyls depends upon the side that is being analyzed. A 180-degree flip will cause the rotation to flip from counterclockwise to clockwise or vice versa. When the compound is aligned in a way that it can be rotated clockwise it behaves in a way that mimics a propeller. It can be noted that if the enantiomer of the compound analyzed was what was to be analyzed every chiral center in the compound would display the opposite…

CHANGES IN CHEMICAL REACTIONS INTRODUCTION This practical experiment is based is based on the theory of Law of Conservation of Mass stated by Antoine Lavoisier. Antoine Lavoisier was a French nobleman who had a major influence on the history of chemistry and biology. Today he is considered to be the “father of modern chemistry.” In all his experiment he supported the Law of Conservation of Mass. Antoine stated this in his theory, “The law of conservation of mass states that mass can neither be…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

A chemical reaction’s rate is described by the amount of product formed. Substances that increase that rate are called catalysts. Catalysts are often proteins called enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points. Enzymes are effective by reducing the activation energy. The enzyme tyrosinase is located in melanocytes. These are cells that produce the pigment melanin. Melanin gives skin, eyes,…

hydrate salt” (Sanders). This will be achievable after finding the masses of chlorine, copper, and water. Introduction In this experiment, the students are using the law of multiple proportions to find the chemical formula for the compound (Sanders). The students will be working with a compound that contains chlorine, copper, and water (Sanders). The empirical formula that is provided to the student is 〖Cu〗_a 〖Cl〗_b∙xH_2 O, and it stands for the copper chloride hydrate (Sanders). I believe…
