Will it Precipitate? Precipitation occurs when two aqueous (soluble solids) solutions are combined and the reaction forms an insoluble solid. When insoluble solids are formed the process is known as a precipitation. An insoluble solid is a solid that cannot dissolve unlike a soluble solid. Therefore only insoluble solids can form precipitates. In the following experiment six solutions were mixed with each other (groups of twos) in test tubes to test which reaction will result in an insoluble solid

Experiment 3: Stoichiometry of a Precipitation Reaction Abstract: In this experiment the objectives were to try and predict the amount of product that was produced in the precipitation reaction of calcium carbonate by using stoichiometry. Then learn how to figure out the actual yield‚ theoretical yield and percent yield of the experiment. Experiment and Observation: The first step in the experiment was to weigh 1g of CaCl2 +2 H2O‚ then pour it into the 100mL

Secondly‚ the experiment accurately measures the reactants and products of a reaction. Also‚ the experiment is to determine actual yield vs. theoretical yield and to calculate the percent yield. For example in this

How Organizational Size Affects HR Outsourcing Name Subject Name of the Lecturer Date Introduction In the world of today mainly ravaged by competition‚ organizations are left with no otherwise but to look and search for new ways of generating value. The universe has clinched the outsourcing phenomenon and companies have incorporated its principles in helping them expand into unreached markets (Abdul-Halim et al.‚ 2009). Strategic outsourcing management is perchance the most significant

to do my Psychology project on does the color of paper affect memory? I chose this question because i thought it would very interesting and intriguing seeing the end results. My research question does in fact relate to the specialized area i chose. I chose the Experimental Psychologist because‚ it is broken down into a few branches one known as the cognitive psychologist. These Psychologists observe sensation‚ perception‚ learning‚ memory‚ thinking‚ and motivation. My research question relates because

The precipitation allows the trees to grow and does not affect the animals very much. The precipitation does not affect the animals very much because when the rain forest started growing they were already adapted and were fine with the environment as it was or they had to adapt or leave. The trees had no problems

Caffeine...Does it truly affect the body? Everyday millions of Americans go through cups of coffee a day and most people don’t even know how it affects your body. I am one of those people and I have always wondered what caffeine does to my body. This topic interest me a lot because I drink coffee on a daily about 2 times a day and I want to know if there are any short term effects and long term effects and if I should be worried about drinking too many drinks with caffeine in them. I want to find

Precipitation Titration Mohr Method Experimental The chloride ion (Cl-) is an important anion found in solids and solutions. In this experiment‚ the amount of chloride ion in an unknown sample J (NaCl + KCl mixture) of water using the Mohr method is determined‚ which relies on the solubility differences of two anions and the titration endpoint of a precipitate. The net ionic reaction during the titration is as follows: Ag+ + Cl- → AgCl(s) The Ksp for AgCl is 1.8 x 10-10 and

LDoes Globalization Affect Growth? Axel Dreher§ First version: October 2002 This Version: January 2003 Abstract The paper presents an index of globalization covering its three main dimensions: economic integration‚ social integration‚ and political integration. Using panel data for 123 countries in 1970-2000 it is analyzed empirically whether the overall index of globalization as well as sub-indexes constructed to measure the single dimensions affect economic growth. The results show that

Does Music Affect Teens? Can the Music Youth Listen to Affect Their Behavior? Music is often blamed for influencing particular behaviors‚ but does it really do so? Why is music sometimes associated with negative behavior and actions? With music being such a staple in youth culture‚ it seems that each teenager has a “soundtrack to their life.” But‚ are they just innocently listening to their favorite tunes? Or are they in for something more? In the media it seems that certain groups that
