Purpose: This experiment is used to perform a series of synthesis reactions that convert aluminum foil to alum. Alum is used in cooking‚ to treat wastewater‚ and is used in common deodorant. In this lab a series of four reactions will occur to yield alum. Calculations: Aluminum foil: 0.5035 grams Alum & Watch Glass: 21.7691 grams Watch Glass: 15.1560 grams Alum: 6.6131 gram Theoretical Yield of Alum: 2Al(s) + 2KOH(aq) + 4H2SO4 + 22H20 -> 3H2(g) + 2KAl(SO4)2 + 12H2O(s) 0.5035gAl

Computer Access Speech Here at Connections‚ we offer computers to those who aren’t fortunate enough to have one‚ and even offer a subsidy to pay for internet access if it’s needed. Giving these forms of access benefits students by allowing them to worry less about their resources and focus on their work. I believe this step could benefit students at other schools by allowing them greater access to resources they may not have otherwise. Some students aren’t able to afford the things they need

The red house had a red roof‚ it was one story‚ and I had an awesome room. I had a large bed‚ and it had a Disney princess bed comforter‚ a canopy‚ and was the best trampoline I ever had. The kitchen was like a hallway‚ it was narrow and long. My memory of the red house is very vague. I remember the day the movers

How to Write a Lab Report Lab reports are formal papers that describe and analyze lab experiments. They follow a very specific format. If you study this paper carefully and follow its directions‚ you will find that these papers are not at all difficult and can have a positive impact on your Biology grade. Paper formatting: The paper should be typed and double spaced. Use a standard 12 point font (do not use cute fonts or colored paper!). Except for the title and abstract – each section

The Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect
