The Differences and Similarities of a Dog and Cat Two domestic animals that share many common and different elements are dog and cat. Despite being different species they exhibit many surprising similarities. By examining these characteristics of each animal can become helpful when selecting a pet. Domestic dogs and cats share many common elements. They both make great companions as pets and are very loyal to their handlers and family members. Dogs and cats also have over two hundred breeds

Define and describe ionic and covalent bonds. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. A covalent bond is the chemical bond that involves the sharing of pairs of electrons between atoms. A compound is made when two or more atoms form a chemical bond‚ linking them together. The two types of bonds are ionic bonds and covalent bonds. In an ionic bond‚ the atoms are bound together by the attraction between oppositely charged

Alison McWeeny Midterm Question #1 William and Dorothy Wordsworth not only have a connection through marriage‚ but also through Literature. Both have their own significant way with their own writing containing few similarities‚ but also a few differences. In reading over their material‚ you see that they both have written on the topic of daffodils next to a lake. After reading these two poems thoroughly you will start to notice that they are writing about the same time and place‚ but in total

The Ionic Lattice In most ionic compounds‚ the anions are much larger than the cations‚ and it is the anions which form the crystal array. The smaller cations reside in the holes between the anions. Basic Concepts: 1. Ions are assumed to be charged‚ incompressible‚ nonpolarizable spheres. 2. Ions try to surround themselves with as many ions of opposite charge as closely as possible. Usually in the packing arrangement‚ the cation is just large enough to allow te anions to surround it without

Ionic Radius: Definition‚ Calculation‚ and Trends Atoms are microscopic particles that constitute all matter. Despite their tiny size‚ however‚ they can be measured. One way that certain atoms‚ called ions‚ are measured‚ is by ionic radius. The radius is different from an atomic radius and is influenced by the particles’ charges. Use the following information to understand this important measurement in chemistry. What is Ionic Radius? Ionic radius is‚ simply put‚ the radius of an ion. An ion is

Chapter 1: Introduction Chapter 1: Introduction Ionic liquids (ILs) can be viewed as a new and remarkable class of solvent. They are also a type of materials that have a long and useful history‚ where the earliest material that meets the current definition of IL was observed in the mid-19th century when a separate liquid phase called the “red oil” was observed in Friedel-Crafts reaction [17]. Over the following years‚ there has been a rapid growing of interest in ILs due to the realization

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance

Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is
