Band-pass filter

A strip of magnesium (Mg) ribbon was cut with a scissor. Said piece had a length of 6 cm, and a weight of 0.071 g. The magnesium piece was rolled into a compact ribbon. After that, with copper turnings the mg piece was covered. Next, 700-mL of water was placed into a 1000-mL beaker. Then, the copper-wrapped magnesium was placed in the beaker. A 100-mL graduated cylinder was filled completely with water. After, said cylinder was covered with a small piece of paper towel over the entire rim, and…

Mass of copper sulfate and tare weight of the beaker – Mass of 100 mL beaker = Mass of copper sulfate 53.84g – 50.89g = 2.95g The mass of the copper sulfate is 2.95g. 3. Mass of starch and tare weight of filter paper – Mass of the filter paper = Mass of starch 3.46g – 0.50g = 2.96g The mass of the starch is 2.96g. 4. Mass of water / Mass of Mixture #6 x 100% = Percent of water 32.68g / 38.59g x 100% = 84.68% The percent of water in the mixture is 84.68%. 5. Mass of…

be smaller than the other and also have a lid. We can’t forget the grinding tools, straining materials, and storage containers. A coffee grinder works perfect for grinding the plant matter. I like to use cheese cloth for primary straining, coffee filters for the final straining and mason jars for…

factor that affected the results obtained was that we used a folded paper instead of fluted filter paper. A fluted filter paper is preferred over a folded filter paper because it has more surface area and also helps the filtration to take place faster. Since we did not use the fluted filter paper during the filtration some solvent evaporated resulting in premature crystallization and the solute stayed on the filter paper along with the impurities, making the percent recovered lower. The melting…

Firefighters-from career veterans with twenty or more years, to volunteers with only a few months under their belts-go through intense, rigorous, and extremely important training. What could happen if firefighters just did the minimum amount of training required and that was all they trained? THE DENVER DRILL On 28 September 1992, in Denver Colorado, a three-alarm fire broke out. During attempts to locate and rescue survivors, Mark Langvardt, a 16-year veteran firefighter, was separated from…

complicated, but many are simple and would significantly improve level of play. One simple change that would significantly improve quality of play is changing the pass-interference rule. Pass interference is is a foul that occurs when a player interferes with an eligible receiver's ability to make a fair attempt to catch a forward pass. The penalty is overcalled, abused by teams and has negatively influenced the outcomes of many games. This year has been especially bad. Teams have gradually…

My business which would be called the FF Facial Defense. This company would be designing a better SCBA, Self Containing Breathing Apparatus, face mask and would be located in the state of Pennsylvania As a firefighter I have seen turn out gear that was able to withstand up to five hundred degrees for five minutes or 1,200 degrees of heat for 8 minutes. However, I have learn from my fire academy instructor and from pictures that our face mask is not able to withstand 450 degrees of heat, but…

however I do know about the theme of that question. Being able to push through when the going gets tough. There are 3 songs that I have chosen that convey the same theme. The writers of these songs are Macklemore a white rapper and Dan Auerbach from the band Cage the Elephant. I intend to analyze “Hold your Head Up” and “Inhale Deep” by Macklemore accompanied by “Trouble” by Dan Auerbach to show how they all convey that we should keep going even when things get hard. The first song “Hold your…
