Pros And Cons Of Weathering Lab

Throughout the course of the experiment, the weight of the beaker and liquid, the weight of the Alka-Seltzer tablet, the weight of the beaker with liquid plus the weight of the tablet, and the weight of the beaker with all of the contents after the bubbling ceased remained roughly constant and did not vary widely. However, a trend is able to be seen in Figure 1. It is clear that as the mL of vinegar used in each experiment run increased, the mass percent of NaHCO3 increased as well. During the construction of Figure 1, experiment runs four and six were deleted to create the expected graph which consists of a gradual increase and eventually leveling off into a plateau.

CONCLUSION These results were achieved by following the directions given by the instructor to its maximum within the limited and unplanned timeframe. Although the experiment was followed in every aspect, there were some discrepancies and limitations due to minor issues. Some of these issues were a limited time window, not enough time mixing to remove gas bubbles, and possible misreading of measurements. When the experiment was conducted, there wasn’t enough time to mix the CO2 bubbles out of the Alka-Seltzer and water mixture. Another thing would have been the misreading of the weight of the scale the first couple of times.

It was hypothesized that Cup 3 with the soda water would have the greatest amount of chemical weathering because of the soda water having the highest pH balance at the beginning of the experiment. Seeing that is was the most acidic; would create the most results. After conducting the experiment, the hypothesis was incorrect. After completing the experiment, the results for the soda water ended up being the cup with the second lowest change in mass of the rock. The rocks beginning weight began at 11.7g and ending at 11.6g., resulting in a change of -.01g. The rock that was in Cup 1 with the 50% vinegar solution had the greatest change in mass. The rock weighing at 8.3g, and then weathering down to 7.0g. Cup 1 had a total change of

Chemical changes occurred in five out of the eight experiments completed in this lab. Although the main focus of experiment two was

The total mass before mixing the substances was 163.05g and the total mass after mixing the substances was 163.05g. In part B, the experiment was between sodium bicarbonate and vinegar in an open environment. The total mass before mixing the substances was 13.15g and the total mass after mixing the substances was 12.79g; there was a loss of 0.36g. The reason the total mass after mixing in part A had remained the same was because it was in a closed environment where the gas was contained and unable to escape. The reason the total mass after mixing in part B had decreased was because it was in an open environment and it was

The last article talks about the 59th Unnamed Cave, in Florida. This cave is located in the eastern part of the Florida Panhandle. From the dates of the artifacts and the dates of the glyph, the site was occupied in the Late Woodland period. The cave was discover in 2007 when a group of cave explorer saw fine engravings on the wall. This site was the first cave art site that was found in Florida and it is the second rock art site that was found in the states. Rock art is very rare in Florida, but now with the site found there is a wider perspective on the importance of rock art. The site did not only include the petroglyph drawing of the past, but it included some artifacts that was use to help date the time that the cave was occupied.

High Noon and “The Most Dangerous Game” are both amazing stories to watch or read. The growth of the characters and how the plot plays out is incredibly interesting. At High Noon, Will Kane faces off with Frank Miller without much help at all. In “The Most Dangerous Game”, Rainsford faces off with General Zaroff and has to overcome his fears. When comparing them side by side, you notice the uniqueness of each story and also how they are alike.

Does the tile have an effect on the spatial dispersion of nitrate in the groundwater and stream?

What type of weathering is when a chemical change occurs and a new product is created from the material that has undergone weathering.

Christopher and Kate noticed that after a rainstorm some of the rocks in their yard appear to shrink. They wondered how the mass of the rocks changed when dissolved in water. To

Mechanical weathering is when physical procedures naturally breakdown rocks into reduced pieces. Chemical weathering changes the materials that are part of a rock into new resources. Examples of chemical weathering are water, acids, and oxidation. Water is important in chemical weathering because, most substances dissolve in water and acids are also essential since they increase the rate of chemical weathering even more. Lastly, oxidation which is when an addition of oxygen to a material is applied it creates an oxide. Which is a

Atmospheric deposition is the process, long recognized by scientists, whereby precipitation (rain, snow, fog), particles, aerosols, and gases move from the atmosphere to the earth's surface. Materials reaching the earth in precipitation or as dry deposition originate from a variety of air pollution sources and can be harmful to the environment and public health. Acidic deposition is the most widely acknowledged form of atmospheric deposition, with well-known effects on lakes, streams, and forests. More recently, atmospheric contributions of nutrients have received increasing attention, particularly as a source of excessive nitrogen entering the Chesapeake Bay. In addition, atmospheric deposition may be a significant source of environmental

L.G. Everist creates monuments with enduring elegance. Our monuments are made from Quartzite, one of the world’s most beautiful and strongest stones. Perfectly formed “moons” occasionally appear in the stone. Legend has it that these moons are spots where spirits have touched the stone and left their mark; thus, each piece is unique and has nature’s own fingerprint.

Subsequently, two porcelain crucibles were used, weighed, and heated for about 10 minutes and then placed into a desiccator to cool. The two empty porcelain crucibles were first heated because the heat would vaporize any impurities that were originally on the crucible. The first crucible weighed 11.9047 g and the second crucible weighed 12.3735 g. Once the mass of the two crucibles

There are a variety of different sites that have been effectively treated using phytoextraction techniques. These include industrial and municipal landfills, agricultural fields, military bases, fuel storage tank farms, gas stations, army ammunition
