180 Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write net ionic equations for

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

Two things that comes to mind whenever people say the name Barry Bonds is the most homeruns ever hit in a players major league career and the use of steroids. As we all know or at least should know Barry Bonds is the all-time leader in homeruns with 762 in his career. It only took Bonds 22 years to hit those 762. Most players are luck to hit 500 in that amount of time. Questions began to rise when Bonds was not only breaking records but putting stats up such as. Although 1998 belonged

Purpose: The purpose of the lab was to observe what happens when two ionic compounds are combined in a small area and to be able to record the type of precipitate that is formed. Background: An ionic compound is formed when ions “transfer‚” or lose or gain electrons. The ions in an ionic compound are held together by ionic bonds in a lattice shaped structured. They are packed tightly together to maximize the attraction between the ions. When two compounds are mixed together‚ they form a precipitate

Response to the deal was divided‚ even if the bonds had been there in the past‚ the level of debates on the matter raised the danger of debt payment ability of the debtors. The affiliation was viewed as a plus to Walter Disney Corporation and U.S economic system where its quest doubled up from $150 million to $300 million.

2. I noticed that all of the ionic compounds are soluble in water. This is due to the fact that water molecules are polar. Meaning that they have dipole bonds‚ which have a slightly positive and slightly negative end due to electronegativity differences between atoms. When ionic bonds are placed in water‚ they dissociate into their ions (positive and negative) due to the process of dissociation. These ions are then attracted to different dipoles present in the water molecule‚ in other words the negative

He’s got a goofy personality- Harry’s 21‚ but 6 at heart. For example Harry started twerking to the host of the show beatboxing‚ then later that night he tweeted “Note to self. Don’t ’twerk’.” Then after that he was casually sitting behind Rihanna peeling and eating an orange‚ you would think an 18 year-old would be more sophisticated at an award show‚ not Harry! On the topic of being sophisticated at award shows he‚ and the whole band‚ decided to eat hot dogs instead of drinking champagne. What

Paragraph 1 In this paper‚ we take a look at the different phases of the Cs3H(SeO4)2 polymorphs. There are 3 different phases that is observed and each of them is influenced by the temperatures. In addition‚ in each phase‚ the polymorph exhibits different crystal structure. At the room temperature of 298K‚ it will be in phase 3 whereby it takes the structure of monoclinic-C2/m

Can a strong bond last throughout many hardships? In Of Mice and Men by John Steinbeck‚ a strong bond lasted between two migrant workers during the Great Depression‚ the time period in which Steinbeck grew up. After struggling at a past job‚ two migrant workers have finally found a ranch to work at that will help them in the future but many problems caused this plan to downfall. Although George and Lennie are two totally different people‚ throughout the story they have created a strong family connection
