iLab‚ Week #2 CATIONS AND ANION LAB Introduction In this experiment we will be mixing two ionic compounds: potassium chromate and lead nitrate; both are soluble in water. This will be demonstrating a double-replacement reaction/reactions between cations and anions. If a reaction does occur it will form a precipitate due to one of the newly formed compounds not being soluble in water. Once the experiment was completed there was what appears to be a “solid” substance remaining in the

Explain why fluorine has an oxidation number of −1 in all its compounds other than fluorine gas‚ F2(g). 4. When atoms of one element combine with atoms of another element‚ is the reaction a redox reaction? Explain your answer. 5. a) Use the oxidation number rules to find the oxidation number of sulfur in a thiosulfate

Adriana Zuniga LAS 377‚ Making a life vs. Making a Living When comparing the processes of making a living and making a life both differ very much‚ but both play a role in the process of finding true success as an individual. Making a living is geared towards plain survival. In our society plain survival would be to pay the bills‚ buy food‚ buy clothes‚ pay the rent…etc. The idea is to settle for the least possible in order to get by‚ or as we call it survival. Making a life is geared towards knowing

Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

thin-layer chromatography. BACKGROUND REQUIRED You should be familiar with extraction‚ evaporation‚ and thin-layer chromatography techniques. You may wish to review the TLC lab from earlier in the semester! BACKGROUND INFORMATION In organic molecules‚ carbon may exist in several different oxidation states. In typical organic compounds‚ the oxidation number for carbon may vary from –4 (a very reduced form of carbon‚ such as carbon in methane) to +2 (a very oxidized form of carbon‚ such as carbon in

Light Microscopy Lab Lab write-up 1 Parveen Rajper Biology 101 Principles of Biology 1 September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult

study a set of metals and their reactions reactions using different metals in an ordered activity series‚ the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing

Ions are charged molecules or an atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons. Conductivity is the measurement of the ability of an aqueous solution to carry an electric current. In this lab we produced conductivity tests to discover the differences between molecules and ions of various solutions such as Glucose‚ Sucrose‚ Ethanol‚ Sodium Chloride‚ Calcium Chloride‚ distilled‚ tap‚ pond and ocean water. The main point of the experiment was

Introduction An appropriate decision making has played a major role in the success of any business management. The success of the business and projects is depending on the decision making of the management and leadership. Making good decisions is fundamental to obtain a good performance in organisation. There are some decision that make huge consequences that can change the role in the organisations and can changes the process of operation of the companies‚ the choices that the organisations daily
