different features that come about by using oxidation reduction and recording the observations‚ these tests will help determine the specific qualities each solution has. Hypothesis I theorize that nothing will happen with Magnesium because it is such a soft metal. Zinc should turn a greener color‚ because that’s what happens to a lot of statues and sculptures. I theorize that iron will tarnish badly because in air it can get tarnished so oxidation must do something as well. Materials 1 Paper

increased the amount of carbon dioxide being released into our environment. The team of researchers also discovered that magnified pyrite (commonly known as fool’s gold) oxidation created acidity that allowed carbon dioxide into our oceans and altered the Earth’s carbon cycle. Over a time period of 10‚000 years‚ glacial oxidation could have altered the concentration of carbon dioxide in the Earth’s atmosphere by nearly

Archaeoraptor: A Prehistoric Puzzle How hard can it be to fool someone? There are fables and scrolls from ages past that tell of the clever villain scheming away‚ plotting to trick the dashing hero. Although it has negative connotations‚ foolery is certainly an art. Humanity is skeptical‚ and to be a true trickster you must be smart‚ and quick thinking as to address any unexpected accusations thrown your way. Some people may say that the Archaeoraptor was a talentless sham‚ but I believe that it

An Oxidation-Reduction Scheme Nicolas Gibson Lab Time: Tuesday 11:30 am Abstract: In this experiment‚ the main objective was to synthesize a ketone from borneol via an oxidation reaction and secondly‚ to produce a secondary alcohol from camphor via a reduction reaction. Therefore‚ the hypothesis of this lab is that camphor will be produced in the oxidation reaction and isoborneol will be the product of the reduction reaction because of steric hindrance. For the oxidation step

Preparation of food takes a lot of time. Even if the dish is only composed of fruits. A lot of dishes have vegetables in them. These can also be useful especially when preparing lots of different food at the same time. If you look at cooking websites they will suggest to use lemon water. In our experiment we will attempt to find out which is better at preserving the sliced‚ chopped‚ and or diced food. Since our experiments are limited by time and costs‚ we will stick to the simplest of the available

Problem This analytical puzzle involves a census worker asking a mother for the ages of her three children. We are told that the product of the children’s ages is 36‚ and the sum of their ages is the same as the address of the house to the north. After being given this limited information‚ the census worker looks at the address next door‚ and returns to ask the mother for more information. The mother simply tells the census worker that the oldest child is sleeping upstairs. Analysis The first

9.1.1 Define oxidation and reduction in terms of electron loss and gain. Oxidation: the loss of electrons Reduction: the gain of electrons 9.1.2 Deduce the oxidation number of an element in a compound. Always determine elements that never change their oxidation number then ensure the charge of whole molecule is right. N.B. Atoms in elemental state have oxidation numbers of 0 9.1.3 State the names of compounds using oxidation numbers. Example of this in iron‚ can be iron(II) or iron(III) 9.1.4 Deduce
