Nitrogen oxide

precipitate was allowed to settle to repeat the decanting process again. In the fourth reaction, 15 mL of 6.0 M sulfuric acid was added to the copper (II) oxide while stirring. The balanced equation for this reaction is as follows: CuO (s) + H2SO4 (aq) à CuSO4 (aq) + H2O (l) + SO2 (g) When the sulfuric acid was added to copper (II) oxide, the solution turned blue. This was due to the formation of aqueous copper (II) sulfate, which produced the copper ions to change the color of the solution

Nitrogen Nitrogen, symbol N, gaseous element that makes up the largest portion of the earth's atmosphere. The atomic number of nitrogen is 7. Nitrogen is in group 15 (or Va) of the periodic table. Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which

is usually the first stage where Platinum breaks apart the bonds of the Nitrogen Oxide by making stronger ionic bonds with the Nitrogen than the Covalent bonds present between the Nitrogen and Oxygen. Therefore, the Nitrogen molecules form a strong bond with the platinum and the Oxygen forms a strong diatomic bond which ensures that it won’t re-bond with nitrogen as its valence shell is complete. After a while, the Nitrogen atoms will similarly form a diatomic bond, N2. The second stage is the oxidation

strongly that water molecules cannot separate them, and they form an insoluble ionic solid.² When copper hydroxide is heated (in reaction 3), water is released as copper hydroxide decomposes into a second insoluble compound, copper(II) oxide. Copper(II) oxide, a base, then undergoes an acid-base reaction in reaction 4 with the addition of aqueous sulfuric acid, H2SO4 . The water-soluble salt, copper(II) sulfate, CuSO4 forms. These five reactions will be performed in the laboratory and will demonstrate

In 1899 ionic conductivity was observed in a solution of ZrO2(Y2O3) however the potential for use in oxygen separation technology has only gained attention in the last 35 years. The best oxygen separation capabilities are seen in defect free ceramic membranes and result in 100% pure oxygen. There are a number of different structures that ceramic membranes can take fluorite, perovskite, pyrochlore, brownmillerite and some others. The main two are the fluorite and perovskite type, which will be discussed

this study Nitrous oxide is an important green house gas. The global warming potential for nitrous oxide is 298 times higher than that of carbon dioxide over a 100-year time horizon (Ravishankara, Daniel and Portmann, 2009). Nitrous oxide is also contributing the third largest radiative forcing globally (Oenema et al., 1997). With the recent emphasis on control of global warming, ways to reduce nitrous oxide are highly sought. Natural sources account for 62% of total nitrous oxide emission globally

areas, plant and animal production. The production of plants requires large amounts of water, between 200 and 500 liters per kg of product, and high mineral content in the form of fertilizers. Each hectare of land gets an input of around 100 kg nitrogen, 16 kg phosphorus, and 100 kg potassium. The effects on the environment are determent on the amount used and the farmer’s skill in using the correct application timing and rates. What is not used in the plant production can be dispersed into the

Background Since the Industrial Revolution, there has been an increased presence of pollutants and carcinogens in the environment, specif-ically in urban areas.1 The presence of airborne pollutants can lead to an increase in allergic reactions and asthma rates. A common airborne pollutant is carbon monoxide (CO), which is commonly found in diesel exhaust. It is an odorless gas produced from me-thane and non-methane hydrocarbon oxidation.2 The toxic gas eliminates and takes the place of oxygen

Phytoplankton are the basis of nearly all the Ocean’s ecosystems, and require a wide range of inorganic nutrients in order to grow; notably Carbon, Nitrogen and Phosphorous. They take up these nutrient elements according to the Redfield Ratio of C : N : P = 106 : 16 : 1. But phytoplankton also require less obvious nutrients such as calcium, magnesium and potassium. These are often in plentiful supply in the worlds Oceans, and other factors such as the micronutrient Iron can be the limiting Phytoplankton

Since the Industrial Revolution, natural resources have been under increasing pressure. The significant changes in the amount of natural resources we have left have led to many issues, such as global public health and global development. Other areas affected include the loss of forest, water and air pollution, decrease in fresh water supply and degradation of soil. Today we are currently seeing dramatic increases in global population. As the world’s population continues to rise, natural resources
