Oxides

Sulfur oxides, Nitrogen Oxides, and particulate matter. Gorsuch station was a coal-fired power plant. Although they failed to obtain necessary permits and install controls for reducing their emissions, EPA was there to stop them from polluting our precious air with the help of the United States funding. Air is free moving which means air from California has the potential to reach other neighboring states. Sadly, Sulfur oxides is also able to move freely with the help of winds. Sulfur oxides is…

1.1 What is a composite material? Composite materials are materials in which a homogenous matrix is reinforced by a stronger and stiffer constituent that is usually fibrous but may have a particulate or other shape (web.mit.edu). They are produced when two or more materials or phases are used together to give a combination of properties that cannot be attained otherwise. For example steel reinforced concrete, plywood and fibre glass. 1.2 What is a Ceramic Matrix Composite (CMC)? CMCs are a…

WHAT IS FORMALIN? Formalin is the trade name for an organic compound made by formaldehyde and water. It has the chemical formula CH2O and its chemical structure is as shown in figure.1. Uses: Formaldehyde is used mainly in the production of plastics (such as urea-formaldehyde plastics which is used in many manufacturing processes due to its useful properties such as flexural modulus, and a high heat distortion temperature, high surface hardness, low water absorption, high tensile strength, mold…

of copper chloride is 1.49 grams. This demonstrates the transformation of the copper hydroxide being converted into regular copper oxide and with the rest of the mass becoming water. The limiting reactant was the copper oxide and the excess was hydrochloric acid. The analysis behind this is that if there was not enough hydrochloric acid, only part of the copper oxide would react and we would lose mass and violate the Law of Conservation of Mass. The errors for this function could be that when…

many previous studies indicate that the CuO or Cu(III) oxide is essential for the catalytic oxidation of carbohydrates. Therefore, Cu oxide has considerable electrocatalytic activity for the glucose oxidation even better than the pristine Cu. As shown in the Scheme 1, when the Cu NP collides on the inert electrode where the appropriate potential, adaptable for the both the oxidation of Cu and electrocatalytic oxidation of glucose by Cu oxide is applied, the blip plus staircase current response…

negative than that of Al. It can be seen that the potential of the Al electrode shifts in the positive direction and achieves a stable value of about -0.82 V. This is due to the formation of natural oxide layer on the Al surface which is stable in saline environments and leads to ennoblement of the…

the effects it has on the environment. Chemical Sources In the formation of acid rain, natural and human-made sources are known to play a role. Human activities are the primary contributor of chemical emissions leading to acid rain, mainly nitrogen oxide and sulfur dioxide. Human-made contributors include the burning of fossil fuels by coal-burning power plants, factories and automobiles.…

Why Use Zirconia For Your Dental Implant The standard material used for dental implants for a very long time has been titanium. This is because the material is great at fusing with the jawbone. Unfortunately, complications can arise with some patients due to titanium exposure, such as an allergy that does not make titanium a viable option. Zirconia is an alternative material to titanium, and offers the following advantages. Less Allergic Complications The primary reason patients use a…

prediction about the phenolphthalein turning the heated compound X into a pink liquid was supported, which means that it is not a base or an acid. The hypothesis was also backed up – compound X is a salt (calcium carbonate (CaCO3) =(heat)= calcium oxide (CaO) + carbon dioxide (CO2)). Additionally, the phenolphthalein did not change compound X’s color, so the prediction and the hypothesis were supported – compound X is a salt. Furthermore, the experiment with the litmus paper has the same…

When copper is exposed to air it oxides, which then cause the copper to form a green/bluish pigment that surrounds the copper entirely which is also known as Verdigris. A perfectly good example of verdigris is the Statue of Liberty which was made from pure copper which then oxides over a long period of time with oxygen as well as water causing the green color. Copper is found in many appliance people use…
