Naming the Minerals Essay Example for Free
Naming the minerals Essay bring in the minerals below. Then, insert a percentage of how legitimate you atomic number 18 in your identification. Finally, explain your percentage of receivedty What was confusing about this mineral? What other minerals do you think it could be?Remember, the minerals in the virtual lab intromit s til now of the undermentioned borax, calcite, corundum, graphite, gypsum, orthoclase feldspar, fools gold, quartz, talc, and topaz.Identification of MineralPercent CertainExplanation of CertaintyExample fluorspar80% certainI am most certain this mineral is fluorite, that I am non completely convinced(predicate). Fluorite and gypsum are both white, shiny, have white streaks, cleave, and show no answer to acid. However, the special gravity of this mineral is 3.18, which is higher than gypsum, so I am pretty sure it is fluorite. Mineral 1 Pyrite80% certainI am almost sure that this mineral is pyrite because it is gold and has a black streak. The only thinks that do not summate up is the specific gravity and the hardness. Mineral 2 Talc atomic number 6% certainI am certain that this mineral is talc because the hardness, specific gravity, color, streak and acid reaction are all the same. I am almost sure that this mineral is pyrite because it is gold and has a black streak. The only thinks that do not match up is the specific gravity and the hardness.. Mineral 3Calcite100% certainI am certain that this mineral is calcite because it is the only mineral on the list that is white and had an active bubbling acid affect. Mineral 4 Orthoclase Feldspar90% certainI am almost certain that this mineral is orthoclase feldspar because everything matches but the hardness. The only other mineral it could be is corundum and the hardness is nine and I feel that that is centering too high to be my mineral. My mineral matches best with orthoclase feldspar. Mineral 5Quartz100% certainI am almost certain that this mineral is quartz because it completely matches the description. Mineral 6 Gypsum100% certainI am certain that this mineral is gypsum because the color, specific gravity, hardness, streak, luster and cleavage all match up to gypsum Mineral 7Graphite90% certainI am almost certain that this mineral is graphite. The only thing that does not match up is the acid reaction. When I ran the test I did not see any reaction with the acid but graphite does react to acid. I did not see any other options because the mineral is black and the streak is brown. So I amalmost positive that the mineral is graphite.Part 3 SummaryWrite a summary answering the following What are the four requirements for a material to be classified as a mineral? How do you differentiate between minerals? Briefly summarize the six methods to tell minerals apart. Summarize the major differences between minerals and rocks.For a solid to be classified as a mineral it must meet these four requirements naturally solid, formed by inorganic processes, hav e characteristics of crystal structure, and a specific chemical composition. In rear to tell minerals apart you can use these six methods luster or color, streak, specific gravity, cleavage fracture, hardness, and acidity. brilliance is the intensity that light reflects off of a mineral. A mineral may be shiny, pearly, or even metallic. Some minerals may be distinguishable by their color. By dragging a mineral crossways a streak plate its mineral powder will leave a streak with a particular color, but this is not a very reliable way of identifying a mineral. By dividing the weight unit of a mineral in water by the weight of the water you can get the specific gravity of a mineral. Another method is by determining if the mineral has cleavage or fracture. When busted a rock will either be in rounded chunks, fractured, or it be monotonic with corners, cleavage. Using the Mohs Hardness Scale you can determine minerals hardness. Hydrochloric acid placed on a mineral will determine whether a mineral contains calcium carbonate. The difference between minerals and rock is that rocks are aggregates. This means a collection of minerals that intergroup together sometimes many kinds in one rock.
