Kevin McDonald Question How much power can I get from a tomato‚ a orange and a lemon and can it light up a small light bulb? Hypothesis If I put a copper nail and a zinc nail in a tomato‚ orange or lemon it should be able to power a small light bulb. Materials *few different citrus fruits *copper nail *galvanized (zinc) nail *LED light or opaque light bulb with a 2 inch lead *crocodile clip or electric tape *micro ammeter Procedures Step 1.Prepare your fruit for the experiment by squeezing

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 + b‚ where y = absorbance‚ x = concentration‚ and b = 0 using a calibration curve to establish the range of concentration

more practical approach is the determination of the tendency of certain metals to corrode in a particular electrolyte‚ such as sea water. This is termed the galvanic series of which the following table is an abridged form. Active or Anodic Magnesium Zinc Mild Steel Wrought Iron Cast Iron Ni-Resist 18.8.3% Molybdenum SS‚

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom

Investigatory Proposal: Organic Batteries VS Commercial Batteries (7-Rizal Grp.5 2009-2010) I. Introduction A. Background of the Study In the 21st century‚ billions of people rely on electrical energy in one form or another. Today‚ even in some of the most remote regions‚ electricity powers lights‚ radios‚ televisions‚ and many other devices that help people to be more productive‚ comfortable‚ and informed. In some places‚ electricity is generated by hydro-electric dams or coal-fired power

Greener Brominations Abstract In this experiment‚ trans-stilbene was brominated and debrominated with the use of three methods: bromination with pyridinium tribromide‚ bromination with hydrogen peroxide and hydrobromic acid‚ and debromination with zinc. The yields of parts A‚ B‚ and C are as follows: 68.6 %‚ 54.6 %‚ and 55.9 %. Introduction In the chemical process of bromination‚ an alkene is halogenated with bromine. Solvents that are typically used include methylene chloride and carbon tetrachloride

TREATMENT OF CORROSION Regardless of the type of corrosion or the metal involved‚ corrosion treatment requires three basic steps: 1. Remove as much of the corrosion as possible. 2. Neutralize any residual material. 3. Restore the protective surface film. CORROSION REMOVAL As previously discussed‚ the first step in corrosion control must be cleaning the surface. After the surface is completely clean and it is determined that corrosion does exist‚ the damage must be carefully assessed

catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion of air into the system. An initial zinc mass of 2.1305g was reacted with 10ml of sulfuric acid. I added the 10ml

gases like ammonia which is hazardous to nature and human health‚ as well as it will increase consumption of zinc. In the present research work‚ Zinc coating on low steel sheets has been developed by mean of galvanizing process with varying the different types of Eco-friendly fluxes and conventional fluxes to study its effect on the corrosion performance & other physical properties of zinc coatings. Quality of this galvanized steel is characterized by AC impedance spectroscopy. Coating thickness
