However seasoned wood should burn quickly because of its relative dryness. I found that white oak has an excelent rating for burning. It has a high heat yeild and the burn difficulty is easy. It is hard to split. It produces light smoke and no sparks.
They are both very soluble in alcohol and hexane so that doesn’t help, but in water ethyl ether is semi soluble and pentane is in soluble. This would make us lean toward pentane but we felt strongly that ethyl ether because of the density was a much better test because there is much less human error and the we asked about how do you decide if something is insoluble
The hypothesis was that liquids will not weaken the magnetism of magnets because only magnetic materials block magnetic fields. This hypothesis was proven in the project because the numbers only increased in very small numbers. Therefore, liquids have a very little effect on magnetic
One of the greatest advantages of nuclear power is that it avoids the wide variety of environmental problems arising from burning fossil fuels such as coal, gas and oil. Currently 78% of Australia’s electricity comes from burning coal. Nuclear energy does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. Thus ‘global
It also has high social acceptability as it is cheap, not dangerous and not power plants are in industrial areas away from homes so it has limited NIMBY issues and noise, light and visual pollution. Wind power has medium social acceptability due to its noisiness and ugliness and positioning near residential areas causing NIMBY issues, however it is popular to some as it is a renewable and green energy source, this means it has low environmental impacts. It has medium economic cost as each turbine costs a lot and only produces a little amount of energy, however it is almost free to run after start up costs. Biofuels have high social acceptability, low cost and low environmental impacts because they are
While hydrogen bonds have a uniquely high surface tension, van der Waals forces have a relatively weak attraction, which causes low surface tension. According to an author of Chem Guide, Jim Clark, in van der Waals forces, “the electrons are mobile, and at any one instant they might find themselves towards one end of the molecule, making that end slightly positive” (2000). In other words, oil is NOT a polar molecule like water, which causes the molecules to not stick to each other as well. The reason tension would occur is because the
A) Subscripts in the reactants must be conserved in the products. B) Coefficients are used to balance the atoms on both sides. C) The law of conservation of matter must be followed. D) Phases are often shown for each compound but are not critical to balancing an equation. E) All of the above statements (a-d) are true.
Sucralose is a substituted disaccharide that is synthesized by the chlorination of the three primary hydroxyl groups, causing inversion of the configuration at the carbon-4 atom from the gluco-analogue to a galacto-analogue. It is a non-nutritional sweetener that cannot be used by the body for energy. Sucralose is extremely useful as an artificial sweetener in the manufacture of foods, beverages, and drugs because it is extremely stable, even at high temperatures and low-pH products and can be used in nearly any product. It is an important consumer product because it does not have a bitter aftertaste like many other artificial sweeteners and because it can be used in baking and cooking. According to the manufacturer, sucralose is used in over 4,000 products across 80 different countries.
It reduces them to a level which is considered safe and not harmful to health however is may not necessarily destroy some viruses. Disinfection should not be used as a substitute for sterilization as it will not achieve the same reduction in microorganisms as sterilization will. Sterilization- Sterilization renders an object free from viable microorganisms, including viruses and bacterial spores. Sterilization can be achieved by steam, hot air, ethylene oxide or irradiation. Autoclaving is the most common method, it uses steam under pressure to sterilize instruments and is the most reliable method.
Unlike gas tungsten arc welding, which can’t be used outdoors because of the shielding gas issue, oxy-acetylene equipment can be used practically anywhere. Some Other advantages to oxy-fuel welding include the relatively low cost of equipment, the quick learning curve compared to gas tungsten arc welding methods, and the ability to easily regulate flame temperature by adjusting the gas flow. In oxy-fuel welding, a regulator is used to control the pressure from the tanks and into the hoses. The operator then adjusts the flow rate through a set of needle valves on the torch itself. It’s necessary to establish a constant inlet pressure into the hose, otherwise the needle valves won’t be able to provide accurate flow control, and poor welds will result.
