I am almost done with my General Chem I class, and a requirement of the class is that I pass a nomenclature exam. The exam will have 30 compounds on it, 15 with the formula (requiring me to write the name), and 15 with the name (requiring me to write the formula). I have tried...
When naming chemicals, special terms and abbreviations are common. The cation or positive ion uses the element name, with a Roman numeral if the element has more than one possible charge. If only one element forms the anion or negative ion, the second term is the "root" element name with ...
Chemical testing determines the levels of minerals and organic compounds that affect the quality of water. Chemical parameters include pH, acidity, alkalinity, anions such as chlorides, sulfates fluorides, nitrates, hardness, metals such as iron, manganese, copper, and zinc, BOD, COD, and other ...
The name of a compound usually gives you all the information you need to write its chemical formula. The first part of the name denotes the cation, or positively charged ion that forms the molecule, while the second part denotes the anion, or negative ion. A balanced chemical formula also ...
Naming Ionic Compounds Given The Ionic Formula Given the formula, write the name. Use of the Stock System is outlined. Try the freeMathway calculator and problem solverbelow to practice various math topics. Try the given examples, or type in your own problem and check your answer with the ...
The correct formula is therefore written as follows. Al2O3 Naming Binary Ionic Compounds The nomenclature, or naming system, of binary ionic compounds involves combining the names of the compound's positive and negative ions. The name of the cation is given first, followed by the name of ...
Several phases are referred to in this article by their nominal chemical formulae expressed using this notation form, where C=CaO, M=MgO, A=Al2O3, S=SiO2, W=FeO and F=Fe2O3. E.g. C2S=2CaO·SiO2=Ca2SiO4=di-calcium silicate. To avoid confusion with standard chemical formulae, sub...
Naming Covalent Compounds First element whole name with the appropriate prefix, except mono Second element, -ide ending with appropriate prefix Practice Electornegativity Lecture 3 Is it Covalent or ionic Nonpolar-Covalent bonds (H2) Electrons are equally shared Electronegativity difference of 0 to 0.5...
In contrast to taxonomies, however, they often have multiple relationship types and are really designed to provide a formal naming of the types, properties and interrelationships of entities or concepts in a specific discipline, domain or field of study [2, 3]. Moreover, ontologies provide a ...
We need to start with the structure of water. Now, you might imagine that a molecule with the formula H2O would have its atoms arranged in a straight line, like this: H–O–H. But it doesn’t, and the reason it doesn’t is that the oxygen atom in the middle has two pairs of el...
