Potential error could result in when quantitatively transferring in any step and spillinng or not transferring all of any given solution. When diluting each flask has a different level for where its specific volume is, so overfilling the flask is possible when not being focused on. The condition of each penny can impact the results by if some copper was chipped off, or if anything attached to the pennies could impact test results. All of these could result in a different than desired copper percentage. It is important that the absorbance of each penny be within the range of absorbance the calibration curve has. This is because the curve created for this lab was made with 0.00 – 10.00mL of Cu^(2+)stock solution when using those values idealy this curve should therefore be 0-100% copper percentage. If values were found outside of this calibration curve then there would be problems with either calculations or a different curve would be needed to properly record

I would guess that the surface area has been decreased and the diffusion distance for gas

A few sources of potential error are as follows: loss of product on glassware throughout the experiment, inadequate measuring of chemicals, "impure" chemicals being worked with, and loss of final product during crystallization processes.

Here I am captured in this irritating street where all I can do is listen to music and look at Facebook. I am waiting for cars to start moving and continue with their destination. Little do I know that ahead of me is a two hour traffic. I am already tired, bored, and furious. I cannot believe I took this road home instead of my usual route. Why do I have to try new things? I should stick to what I know. While I sit in the drivers’ sit I am still wondering why I had the bright idea of taking a new way home, a way that I had little knowledge of.

At this time, there is no known value for the volume of carbon dioxide, so % error and accuracy

The Beers Law calibration experiment used many concentrations of crystal violet solutions. Each of these solutions were test and analyzed in order to determine the absorbance of each concentration The results were than graphed and produced a slope of 1.00E05 with an intercept of -2.21E-02.

Caleb Logan Bratayley had a big smile and a heart of gold. The member of the Bratayley family was seen by viewers around the world as he performed on video for the masses to watch YouTube fans and pop culture junkies were devastated to hear that the promising entertainer has died. According to US Weekly on Monday, Caleb Logan passed away over the weekend from natural causes.

Like many communities in Tennessee, Briceville's founding was tied to coal mining. Originally known as Slatestone Hollow, early miners used wagons to haul coal to Knoxville until the railroad connected Knoxville and Coal Creek. In 1888, Calvin Brice, who was then the president of the Lake Erie and Western Railroad and would later serve a single term in the U.S. Senate, requested the construction of a spur connecting Slatestone Hollow with Coal Creek. Upon completion of the spur, the community was renamed in Brice's honor. Although the population of Briceville has risen and fallen since the community's founding, residents have never been short of pests. Two common pests found in the area are bed bugs and fleas.

At Brewton-Parker College, the campuses community is quite small. I cannot decide if it is a good thing that everyone knows each other. Because the school’s population is not quite as high as a big university, everyone knows everyone’s business. No matter what someone does, good or bad, it gets out, but for me the size in beneficial. The less people there are, the less chance I have of getting distracted. I love how small the classes are, too, because my teachers actually knows who I am. Also, when I need help with what we’re learning or I just have a simple question, I can easily ask my teacher, and he or she can help me better understand what is going on. The teachers here, at Brewton-Parker College, are kind and beyond willing to help me, no matter how long it takes; help is always there when I need it. For instance, the library has become my best friend. I like how I can go and have my own table to get a good amount of work done, and the books are such a useful resource for

The town of Bannack was established on July 28, 1862 due to gold strike at Grasshopper creek. The city was small and put together quickly with logs, but briefly served as the capital of Montana Territory in 1864 (Bannack, Montana, 2017). Bannack was very remote and it was only connected to the rest of the world by the Montana Trail which lead to extremely high crime rates and a low population. The miners in Bannack earned $8 a day which is equivalent to a pound of chewing tobacco and a dollar as change. In 1865, the residents relocated to more productive gold sites situated along Alder Gulch.

Bronfenbrenner Analysis Name: Course: Tutor: Date: Urie Bronfenbrenner is today credited and known in the psychology development field for the development of the ecological systems theory constructed to offer an explanation of the way everything in a child and their environment affects the whole child development. Bronfenbrenner ecological theory has levels or aspects of the environment containing roles, norms, and rules defining child development namely the microsystem, the mesosystem, the exosytem, the macrosystem and the chronosystem. The subsequent discussion offers an analysis of these levels and their influence to child development, and then offers a personal analysis of the influence of the ecological theory in decision making.

In this lab an attempt was made to determine the concentration of a Ba(OH)2 solution by using the conductimetrically determined equivalence point of the reaction between Ba(OH)2 and H2SO4 and by gravimetric determination. The molarity using the equivalence point was determined to be 0.076 M, with a percent error of 24% (actual value was 0.100 M). The molarity using gravimetric determination was 0.0835, an error of 17%. One possible error is the presence of bubbles in the buret. Bubbles would have caused the buret reading to be too high, resulting in a larger equivalence point. Another possible error deals with the colloidal nature of barium hydroxide due to its relatively low solubility. The colloidal barium hydroxide would make it
