Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order. Using this information‚ the rate constant was determined to be 0.408 M-1S-1‚ the units indicating that the reaction was a second order

1.0 Introduction of Investigation Investigation can be defined quite simply as a systematic fact finding and reporting process. It is derived from the Latin word vestigere‚ to “track or trace‚” and encompasses a patient‚ step-by step inquiry. Investigation is finding facts; it is akin to research conducted in the academic arena. Investigation is a multi-disciplined field of study. It encompasses law‚ the sciences‚ communications‚ and a host of other things. Investigation requires an inquisitive

Competency Goal VI To maintain a commitment to professionalism Functional Area #13: Professionalism As a professional I attend regular trainings both in and out of work. Some training is provided for me by my employer‚ while others I seek out on my own. In June I attended training for 2 weeks before children started attending class. These trainings focused on areas such as health‚ routines and transitions‚ environments‚ goals/objectives and school readiness. One way I apply these trainings

Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

In this essay‚ it will be discussed how the Kinetic Molecular Theory explains many gas law specifically Boyle’s gas law‚ Charles’ gas law‚ and Avogadro’s gas law. To understand what will be talked about is to first know what the Kinetic Molecular Theory is. In our textbook is says it is “A simple model for gases that predicts the behavior of most gases under many conditions.” First off‚ we will take a look at Boyle’s Law. As stated in our lab manual “at constant temperature the pressure which a given
