Copper Chloride Lab Report Procedure Part A: 1. Pick up the container of copper chloride dehydrate‚ and observe material. Describe crystals in detail‚ and write down all of the observations. Part B: 1. Take a 100 ml beaker and fill ¼ of it with water. Use a spatula to add some copper chloride dehydrate to the beaker filled with water. Record the observations. Be sure to observe the water and the copper chloride dehydrate. 2. Stir the contents in the beaker with

Pennies are easily spent and worth one cent‚ so if I was you I wouldn’t let that precious penny walk out of my life. Pennies are very expensive to produce. We have spent over eighty million dollars over the production of pennies‚ while pennies are only worth one cent. Even though some people want to get rid of the penny‚ it would be better if we keep it because it is apart of or culture. Also‚ we could avoid price increases from rounding up‚ and pennies are good for charities. Many people have

Percent Copper in Brass Background The scientific concepts involved in this lab include Spectroscopy‚ Beer’s law‚ Calibration curve‚ concentration‚ and electronic transitions. The main objective of this experiment is to see how the percent composition of brass can be determined to verify the properties influenced by copper and zinc. Brass is a generic term for alloys of copper and zinc. The main technique used in this experiment is Spectroscopy. The three equations used in this lab are: Y = mx

States should keep the penny or stop the production and distribution of it. My claim is yes‚ we should stop the production of the penny. My reasons being that pennies are a waste of space(Jeff Sommer)‚ it costs more to produce them than what they are worth(Jeff Sommer)‚ and with pennies gone‚ retail sales will be rounded up or down(Jeff Sommer). The counterclaim is that we should not stop the production and distribution of the penny. Some people say no to doing away with the penny for the following

In the experiment‚ synthesis of copper compounds‚ the purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible
