measurement scales and why they matter we should first explain what they are. A compound measure allows us to measure different aspects of a topic people would find complex. This topic could range from stem cell research to abortion to gun control. The good thing about compound measures is they have a general reliability to them. What I mean is, if an error is made it often does not make the whole measurement go wrong. Compound measures should have several different characteristics in common…

Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…

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 water. The constants are the surface being…

Comparison of Organometallic Compounds of Transition Metals and Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne,…

3-triazole hybrids is demonstrated in Scheme 1. Compound 2 was prepared by treating propargyl bromide with 1H-indole-3-carbaldehyde (1) in presence of potassium carbonate in dry acetone at reflux temperature [26]. Compound 2 was further reacted by heating at reflux temperature with o-phenylenediamine (OPDA) in chloroform for 6 h afforded compound 3. Compound 3 coupled with variously substituted azides by Azide-Alkyne Cycloaddition reaction to afford title compounds 4a–j. The variously…

which was about 10,000 years ago in the Fertile Crescent. However, pesticides have not always been an organic compound. The first generation of pesticides was composed of inorganic substances, such as sulfur, mercury, lead, arsenic (calcium arsenate and lead arsenate), and ash. The modern era of pesticides was developed in 1940, around the time of World War II. Organochlorine compounds, such as dichlorodiphenyltrichloroethane (DDT), was the first synthetic organic pesticide to be introduced.…

feels right to you. When you make decisions you should trust your instincts. Eli the main character from, The Compound, written by S.A. Bodeen, did this well. He knew his dad was trying to hide something from him. When he started finding clues in his dad´s office, he started to realize his dad has been keeping secrets from his own family for the last six years while they were in the compound. Eli found evidence in his dad’s office like the Cd and then he found that his dad was lying about…

CaBr2 is an ionic compound, because the second element is a non-metal so it will form an ionic compound. The next step in naming an ionic compound, is to name each component as if they were ions. The first component is a cation so you leave the name alone. The second component is an anion, so you change the ending of bromine to "-ide" and it’s becomes bromide. The last step is to combine the names so, CaBr2 becomes Calcium bromide. The first element of the formula NBr₃ is nitrogen a nonmetal,…

this lab is the compound light microscope. During this lab you will check the microscopes by drawing what you see to make sure the high and low powers work properly. After you tested your microscope you take a toothpick and scrap it on the side of you mouth and examine what you see through the microscope, your final results should be a drawing of what you saw through both the high and low powered lens. Introduction- This lab is based on the compound light microscope. “A compound light…
