* What is this substance This substance is iodide Confidence Report The aim of extraction, is to separate a part of raw material, using a solvent such as water with heat. A tincture of iodine is a common medicine sold in many pharmacies, used as an antiseptic on cuts of the skin. The objective of the seaweed lab, is to produce a tincture of iodine by extracting Iodide and other components (seen when a mixture of iodine is present), from seaweed. We
First of all, a pharmaceutical product can be made from seaweed by heating seaweed in water. This causes the product to be extracted from the seaweed. After that, filtration is needed to extract the seaweed from the water. Finally, by evaporating the product can be extracted from the water. 2.
(C) The organisms act as the foundation of the restricted food chain in a manner that is comparable to the role of the phytoplankton. (D) The ability of the ocean depths to support biological life is the result of the interaction between the phytoplankton and the organisms. With improvements in the design and function of unmanned submersible technology, scientists have marine vastly expanded their One of capacity the to accumulate data regarding the less-accessible environments. most significant discoveries relates to the role played by underground vents, fissures in the crust of the ocean floor that expel
Purpose: The purpose of this experiment was to investigate the concept of density by determining the identity of various metal objects based on their experimentally determined densities and by building a “mock” submarine. The basic techniques that this experiment was also designed for was the use of the analytical balance to weigh objects, the measurement of a liquid in a graduated cylinder, and the use of a caliper Procedure: PART I: Determining the Identity of a Metal by its Density Step 1: Two unknown metal objects that were to be investigated were collected. Step 2: Close observations were made about the markings, color and conditions of the Table 1: Unknown Metal Observations Metal | Color | Markings | Metal 1 | Copper | Tarnished | Metal 2 | Silver | Slight scratches | Step 3: A standard weighing technique was used to weigh the metal unknowns on the analytical balance provided. The objects were wiped with Kimwipes to remove any fingerprints, etc. Table 2: Unknown Metal Masses Metal | Mass | Metal 1 | 57.3564 g | Metal 2 | 18.0893 g | Step 4: Volume by displacement was used to find the volume of the objects.
The Army also relies heavily on these two components to provide constant security and protection of our waterways to include underwater volume and maritime power protection. By the Navy executing this primary mission greatly assists the Army in conducting any required missions worldwide. The Navy also provides mass movement of military equipment for the entire deploying force. Just take a good look at the amount of equipment that was transported over to the Persian Gulf War back in 1991. The massive amount of equipment that was shipped over to this war in such a short amount of time was truly incredible.
Sea floor spreading forms the best evidence for continental drift. Critically discuss this statement. There is lots of evidence to support the theory of continental drift, including Harry Hess’s discovery of sea floor spreading theory. By using sonar, Hess found that oceans were shallower in the middle, allowing him to identify Mid Ocean Ridges. He suggested that at the centre of oceans, molten material would rise from the Earth’s mantle, causing new sea floor to be created, pushing the ocean floor.
Tig Welding Tig welding is also know as Heliarc or GTAW ( Gas tungsten arc welding ). Tungsten inert gas (TIG) welding is the process of blending together reactive metals such as magnesium and aluminum. The TIG welding method became popular and useful in the early 1940s and, as a result, has greatly propelled the use of aluminum for welding and structural processes. TIG welding is commonly used for both high quality and manual welding. During the process of TIG welding, an arc is formed between a pointed tungsten electrode and the area to be welded.

Fracking: Let It Flow First, let me explain the process of hydraulic fracturing - fracking. Fracking is the process of harvesting natural gas from far beneath the earth's surface. This process uses horizontal drilling and hydraulic fracturing to release natural gas from shale beds by blasting the rock with high-pressure water and chemicals. This is not a new idea; oil companies have been doing this for over half a century. Natural gas is an excellent alternative to coal or oil because it burns much cleaner.
Where were you April 22, 2010-Earth Day, just 2 days after the BP oil spill, and how did you help sustain the Earth? According to MSNBC the BOP or blowout preventer, sits directly on top of the wellhead on the ocean floor. In the event a blowout or “kick” occurs, giant valves inside the BOP can seal off the well keeping any oil, gas, and any
