characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright line spectra. This means a bright line spectra can be used to identify any element. This information can be used to identify elements in space to tell whether a planet has oxygen on it or not. If one can tell if a planet has oxygen

of supplying products that are sophisticated and manufactured to very rigid standards from newly developed‚ difficult-to-form alloys. The physical phenomena describing a forging operation are difficult to express with quantitative relationships. The metal flow‚ the friction at the tool/material interface‚ the heat generation and transfer during plastic flow‚ and the relationships between microstructure/properties and process conditions are difficult to predict and analyze. Often in producing discrete

of different kinds of metal. We used pennies made out of different metals to determine this. After we gather the data‚ it’ll be used to determine the metal used. Hypothesis: In the lab‚ I expect that the pennies before 1982 would be heavier than those that are after 1983 because the metal was initially changed because the earlier pennies cost more to make. So I think that since the heavier metal was more expensive to make‚ then they just used a cheaper metal. So if the metal was heavier it may have

Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer

Fathi Habashi Montana School of Kinetics of Corrosion of Metals Mines Butte For better understanding of corrosion processes‚ it is essential a t first to consider the simple cases of corrosion when no insoluble products‚ scales or films are formed. Once the mechanism of these processes is well established‚ it may be possible to understand corrosion processes in general. Corrosion processes in this category (no insoluble end products are formed) can he divided into two broad

reaction occurs on the inner surface of the catalyst. Another way ethylene is produced . . . • Steam (thermal) cracking: ethane is mixed with steam and are pumped into a steam cracker at very high temperatures (750– 900oC) and passed through hot metal coils. The heat from the coils breaks the bonds to change the ethane‚ or the larger hydrocarbons to ethylene. C2H6 ( C2H4 + H2 .3 Identify that ethylene‚ because of the high reactivity of its double bond is readily transformed into many useful

Cobalt Wedding Bands Review Cobalt wedding bands are crafted having a super strong metal that mixes an incredibly higher level of sturdiness using the vibrant reflective appearance of white gold or platinum. Using the many pros cobalt engagement rings have to give you‚ cobalt rings might even at some point exceed tungsten and titanium wedding rings. To discover if this sounds like the best metal for the wedding ring‚ and also to begin to see the benefits and drawbacks of cobalt plus how cobalt

Lemon Battery creating a battery from a lemon is a common project in many science text books. Successfully creating one of these devices is not easy. Batteries consist of two different metals suspended in an acidic solution. Copper and Zinc work well as the metals and the citric acid content of a lemon will provide the acidic solution. Batteries like this will not be able to run a motor or energize most light bulbs. It is possible to produce a dim glow from an LED. The picture at the top

Silver can be consider as one of the most all-around metals reachable. Indeed silver is a white‚ shiny and soft metal which is often found in its natural form as a mixture with other minerals and metals. Thanks to its properties‚ silver can be consider as a multi-function produce because it can be used in the industrial sector and also as an asset. Indeed‚ silver has a monetary value when paper money is no longer of value. For example‚ in period of inflation or deflation‚ the value of silver can
