Chemical element

are all Hydrogen atoms. Instead of the zero neutrons Hydrogen has in its Protium form, Deuterium and Tritium have two and three neutrons respectively. This change in neutron number and therefore atomic weight classify these atoms as isotopes of the element Hydrogen. An ion is an atom with a charge due to changes in the number of electrons (negatively charged particles) in the atom. Ions that have lost electrons have a positive charge, and are called cations. Ions that have gained electrons have…

Benzalknoium salts are acknowledged as benzalknoium chloride, also known as BZK, BKC, BAC, alkyldimethylbenzylammonium chloride and ADBAC. These salts are known to have several names and are also considered as cationic surfactants. Surfactants are compounds that subordinate the surface tension among two liquids or among a liquid and a solid. Surfactants have the availability to act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants. Benzalknoium salts are used in…

Content Stoichiometry is the relationship of the masses of the reactants and products in a chemical reaction. For a given mass of a substance in a reaction, the mass of any other substance in the reaction can be obtained using the coefficients of the balanced chemical equations and the molar masses of the substances involved. The amounts obtainable from a balanced chemical equation are called stoichiometric amounts (Villamar Jr., 2004). As what was said in the introduction, the first topic that…

In the days of asymmetrical warfare: chemical weapons are a mainstay. Chemical warfare has introduced a powerful weapon called blood agents; considered one of the most deadly. No one organization is a primary source of blood agents, but they are a threat of the destruction of organs within a living organism; the human body. The reduced cost of warfare by these agents increases the bang for the buck with less quantity storage or hiding in plain sight made accessible. Past events such as the Tokyo…

with many different elements. A Monomer is an atom or small molecule that may bind chemically to other monomers to form a Polymer Different monomers make up a polymer. Polymers combine to make a molecule, and molecules combine to make macromolecules. Carbohydrates Carbohydrates are molecular compounds made from just three elements: carbon, hydrogen and oxygen, usually in a ratio of 1:2:1. Monosaccharides (like glucose) are relatively small molecules. They…

Iodine: During the course of this project, I have learned many things about the element Iodine and it's contributions to the world. In the early 1800's, Bernard Courtois manufactured potassium nitrate and used seaweed ash as his mains source of potassium. one day in 1811, Courtois added sulfuric acid and saw purple fumes which condensed to form crystals with a metallic luster. Courtois suspected that this was a new element and showed it to Charles-Bernard Desomes and to Nicholas Clement who…

then the ionic compound’s empirical formula can be found using this equation by calculating the masses of magnesium and oxygen in this equation: Mg + O2 → MgxOy Since an ionic compound is the hopeful result of this lab, an ionic compound is a chemical compound comprising ions, which ions are an atom or molecule with a net electric charge due to the loss or gain of an electron. Ions can be negatively charged and called anions, or positively charged and called anions. But in this lab, many…

1. Discuss how the measurements in Part I (Small Things) relate to the terms accuracy and precision. 2. What is the width of a single DNA molecule in units of centimeters? [The width of the DNA molecule is given by the distance between any two phosphorus atoms recorded in Part II.] 3. Based on your answer to (2), how many DNA molecules would fit across the smallest dimension of the smallest item (from Part I) measured in lab? Write the number in scientific notation. 4. Using the…

Reactions 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…

Part one Make a 3 list of chemical safety hazards? The three chemical safety hazards are: Poison Toxic Corrosive Reactive Environmental hazards 2. What is Amalgam? Amalgam is mixture of metals of mercury with another metal and other metal. Almost all metal can be an amalgam with a form of mercury. 3. If you had to train someone on how to separate the mercury from the amalgam, what training would they need? WHY? If I had to train someone on how to separate the mercury…
