churches. My first controlled experiment is based on the Statue of Liberty. It is made of copper so I am using pennies in my experiment. (nps.gov. n.d.) My observation is that acid rain corrodes metals. My question: does acid rain corrode metal? My hypothesis is the obvious‚ yes metal structures are in danger of being corroded because of acid rain. That is also my prediction. The experiment will take place over a one month period. I will take two pennies (minted before 1983) and place

MH 45 wingless AbstractTo investigate the effects of mh45 airfoil on performance criteria of wingless body during flight. This investigates the dimensions of a prototype airfoil geometry for a wingless aircraft. The wing is including MH45 airfoil profile and is of swept wing design. The investigation framework dictating is mathemeatical analysis of geometry‚ analysis of geometry using computer aided design‚ parts list and reducing part count‚ mechanical linkages‚ optimisation of parts using finite

Purpose: To use electrochemistry to extract metals from ionic compounds in solution Procedure: -Start by attaching battery snap connector to a battery and fill beaker with between 100 and 200 mL of copper (II) sulfate solution -Connect clip to each of the nickel strips -Place nickel strips in copper sulfate solution without strips touching -Put one clip on the positive side of the battery and the second to the negative side. Observe -Switch clips to the opposite charged sides of the battery

and to an empty orbital close to the nucleus with higher levels‚ so one of the electrons gives off energy. A flame test is a visual test where the energy is in the form of a color change and the change can be seen based off it. Therefore‚ different metals emit different color. When a metallic ion is heated in a flame test the heat‚ presented as energy‚ causes electrons to level from grounded state to excited state. When it returns to a lower energy state‚ the energy becomes a visible light. This depends

We Errors Analysis (Distinguishes percent of error in calculations) Some errors we faced were water being displaced when pouring the metals into the test tubes (could have changed volume). Also‚ we should have given the scale more time to get and exact answer rather than writing down one of the first numbers we saw. Now‚ there are ways we can certainly improve this experiment. One would

The character I picked from The Breakfast Club is Allison Reynolds. This character relates to me by how she is quiet and doesn’t speak much when she isn’t comfortable with the people around her‚ eventually she will become comfortable and show her true self. She is also like me by the way how she lies a lot‚ and how she does admit to lying later on. I lie sometimes‚ just not as much‚ plus my lies aren’t as bad as Allison’s. I can visualize myself‚ and some of my friends in Allison.I can visualize

soft silver metal. If Gallium is held in someone’s hand log enough‚ it will melt. Gallium will melt at a temperature of 85 degrees‚ which is slightly above room temperature. Through the era of semiconductors‚ gallium was used as an agent to make allots that melt at a low temperature. The element gallium is a byproduct of the production of aluminum and zinc. Most gallium is extracted from the crude aluminum hydroxide solution of the Bayer process. Gallium easily bonds with most metals and is often
