An error that could have been present during the lab includes not letting the zinc react completely with the chloride ions by removing the penny too early from the solution. For instance, the percent error of this lab was 45.6%, which was determined by the subtraction of the theoretical percent of Cu 2.5% and the experimental percent of Cu 3.64% and dividing by the theoretical percent of Cu 2.5%. This experiment showed how reactants react with one another in a solution to drive a chemical reaction and the products that result from the
The penny, a coin in the United States is valued at one hundredth of a dollar, or one twenty-fifth of a gumball. Over 1.65 trillion pennies have been produced by the United States Mint for circulation since 1792. The United States penny should be taken out of circulation from the United States economy because pennies cost more to make than what they are worth on its face value. The high amount of penny production has led to a large consumption of metals including zinc and copper. Additionally, inflation has caused the penny to have little to no value in today’s economy.
Zombicon, a Fort Myers charity event on its 9th year ended with 1 man dead, identified as Tyrell Taylor, and 5 others injured after shots were fired into a crowd of people.

Over time, pennies receive a dark coating, creating a dull appearance.
In a capitalist world, there are many opportunities to succeed, but an individual must be willing to work hard in order to ascend the social ladder. In Nickel and Dimed by Barbara Ehrenreich, she undergoes an experiment to see whether or not the average low-wage worker can get by in America. Ehrenreich claims that based on the wages that the low wage worker receives, he/she can not really get by and thus they don’t really have a way to get up out of poverty. However, the working poor do in fact have an opportunities to succeed, such as working up the corporate ladder from the bottom and saving money to build wealth, making Ehrenreich’s argument invalid.
