I am a sea-colored blue-green, vitreous, nicely-cut piece of fluorite. Fluorites are slightly-soft rock. We score a 4 on the Moh's scale. It’s not always good to be hard, either. Being soft is another helpful adaptation for lowering the melting point of raw materials in steel production.
Zirconium Zirconium (40Zr91) is the 40th element in the periodic table of elements. Its electronic configuration is 2, 8, 18, 10, 2. It is a lustrous(glossy, shiny) gray transitional metal that resembles titanium. It is both ductile (able to be deformed plastically without breaking) and malleable (differs from ductility as far as it can be hammered/rolled into a thin sheet). It cannot be found as a native metal in nature, The Social benefits and limitations of Zirconium Zirconium is used primarily as an alloying agent because it is highly resistant to corrosion from alkali, salt water, acids and many other possible sources of corrosion.
This lab will also rely on some skills and techniques that were utilized in previous experiments, such as the using of amphoteric metals, amphoteric hydroxide solutions, and complex ion formation. Amphoterism is the ability of a substance to react with either bases or acids. An example of an amphoteric metal is Beryllium. Beryllium and all other amphoteric metals form insoluble hydroxides in limited hydroxide solutions and soluble, complex ions when they are in the presence of excess hydroxide solutions. Similar to Beryllium, Zinc and Chromium are amphoteric, but Iron and Magnesium are not amphoteric, meaning that they form insoluble precipitates in basic solutions like excess hydroxide.
The potential hazards for using sulfur dioxide is it can affect our environment, plants, animals, the air that we breathe, our water resources and our planet. Too much of it an extreme hazard to our health, our planet and
Environmental Science Irma Boric Everest University Online Natural gas is a highly flammable gas that is known as a hydrocarbon mixture. Natural gas is contains mostly methane and is the safest form of energy that we can use daily. When animals and buried plants get exposed to heat natural gas is formed. Because natural gas is a cleaner fossil fuel the carbon dioxide emissions are lower. Natural gas also isn’t high in nitrogen oxide or sulfur dioxide.
We resulted that lead, silver, and copper are the strongest oxidizing agents, and that magnesium and zinc are the weak oxidizing agents. The strong oxidizing agent oxidized the weak oxidizing agent and in turn the strong oxidizing agent got reduced while oxidizing the weak agent. When a reaction occurred, the solid metal reduced the ion, and in turn made it the more reactive metal. In part two we used a solvent extraction technique to derive an activity series for the halogens. With the use of this technique we placed chlorine, bromine, and iodine into solutions containing chloride, bromide, and iodide.
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.
The ground water may become contaminated with both organic and inorganic substances which may include heavy metals like Cadmium, Chromium and Nickel, etc. (Christensen et al, 2001). Pharmaceutical wastes can cause cancer within human cells. (Krifa et al. 2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination.
The Hazards of Welding Fumes for the Different Metals and their Symptoms | In this paper I hope to show some of the hazards that are associated with being exposed to some of the different types of fumes produced while welding. The hazardous effect of welding fumes and gases on a welder's health can vary with the different types of metals, the length, the amount of the exposure, and the specific toxicity of the metals involved. The welding process involving stainless steel involves, cadmium- or lead-coated steel, or metals such as nickel, chrome, zinc, and copper can be hazardous as the fumes produced have a higher toxicity level than those which a welder breaths when welding mild steel. Mild steel will consists mostly of iron, carbon, and small amounts of manganese, phosphorous, sulfur, and silicon. While stainless steel consists’ mainly iron, chromium, nickel, titanium, and manganese.
Reactivity of Metals Background Information When a metal (such as magnesium, aluminium, zinc and copper) is mixed with hydrochloric acid, a hydrogen gas is produced. If hydrogen gas is produced, a pop sound should be heard when a flame is held over the substance. On the periodic table the most highly reactive elements are in the first group and the least reactive are in the last group. All metals have the same properties, they are shiny, they conduct heat and electricity, they are malleable which means able to change shape permanently without breaking or cracking, and they are also ductile which means they are able to be deformed without losing their strength. Aim To compare the reactivity of various metals by observing their reaction with hydrochloric acid Hypothesis That the all the metals will produce foam and a pop.
