ABSTRACT The experiment deals with determining the standard reduction potentials of different electrochemical half-cells through pairing it with Cu2+(0.1 M)|Cu half-cell and then comparing it with the theoretical value. Galvanic or voltaic cells contain the anodic and cathodic cell reactions‚ and in order to get the value of Ecell‚ we add both half-reactions. The more positive the Ecell‚the more negative ΔG would be‚ thus‚ giving us a spontaneous reaction. After comparing the cell potentials

rate change over time? How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a real enzyme because an enzyme’s job is to speed up the reactions and as time allotted. That did happen since the enzyme in our lab was able to make more chainobeads as time progressed. 4. Graph 5.

If the oxidation number of an atom decreases in a reaction‚ it indicates a gain of electrons. • You can balance an equation by finding the coefficients that make the number of electrons lost by one atom of one element equal to the number of electrons gained

Gun Control and Crime Reduction Solution The solution I propose is to deregulate firearm laws and eliminate criminal protection zones through the Buckeye Firearms Association in the State of Ohio. Problem To focus on violent crime or crime reduction in Ohio‚ this paper will offer evidence from other states and countries around the world. Without analyzing firearm laws and crime statistics from other regions‚ a solution cannot be held plausible to reduce crime in Ohio. We must also disregard

Since I started the MSW program‚ stress has been no stranger and during my first semester I was introduced to mindfulness-based stress reduction (MBSR) in one of my classes. MBSR began over 30 years ago at the University of Massachusetts Medical School by Dr. Jon Kabat-Zinn (Noonan‚ 2014). MBSR was originally developed as an 8-week course designed to teach students’ basic relaxation and breathing strategies‚ along with mediation and simple yoga (Noonan‚ 2014). Till this day the course is being used

went to sleep‚ the emotions would send all the memories created during the day down to long-term memory. The emotions could then recall these memories whenever they needed them by requesting them to be sent up to headquarters. Drive-Reduction Theory Drive-Reduction Theory refers to an internal state of tension that motivates an organism to engage in activities that should reduce the tension. In the movie‚ Rylie was unhappy after her move to San Francisco. This creates an internal state of tension

print“We are being advised to reduce our carbon footprint. Discuss the significance of this for the individual and for industry” When talking about climate change‚ footprint is a metaphor for the total impact that something has and carbon is shorthand for all the different greenhouse gases that contribute to global warming (1). The term carbon footprint is a measure of the impact our activities have on the environment‚ and in particular climate change. It relates to the amount of greenhouse gases

Heading: John Francis101 Honors Biology 5/14/15 Title: Classification of Species Purpose: The purpose of this lab is to understand the concept of taxonomic classification and to practice using dichotomous keys for classification. Procedure: To start the experiment with exercise 1‚ I gathered all of the needed supplies‚ both from around my house and from the lab paq CD. I then began exercise one by printing the images in Figure 5 from my labpaq. I then proceeded to cut out each shark. Next

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
