Nitrous oxide

Acidic Environment Oxides of non-metals which act as acids Non-metals burn in air or oxygen to produce acidic oxides. The addition of water to soluble oxides produces acidic solutions. Oxides of non-metals which act as acids include: * Carbon reacts with oxygen when burnt to form carbon dioxide which is acidic in nature. When dissolved in water, it becomes H2CO3 (carbonic acid). CO2 (g) + H2O (l) →H2CO3 (aq) * Sulfur burns in oxygen to

releases nitrogen oxides, sulfur dioxide, mercury, and dozens of other substances known to be hazardous to human health” (Air). There are plenty of chemicals out there that I have never heard of, however, the three listed in the lines above, I have heard before. Although, I do not know much about any of them; so I will look them up. Nitrogen Oxides: “Nitrogen oxides are a group of gases that are composed of nitrogen and oxygen. Two of the most common nitrogen oxides are nitric oxide and nitrogen dioxide

“In what ways do practices of consumption drive ecological degradation?” The consumption of some goods and services results to ecological degradation more than we may realize. The things that we purchase contribute directly or indirectly to pollution, climate change, resources depletion and biodiversity loss. Ecological degradation refers to the “deterioration in environmental quality from ambient concentrations of pollutants and other activities and processes such as improper land use and natural

and nitrogen oxides are released into the air. They then mix with oxygen and water in the air to form acid rain. These chemicals can travel long distances in the rain before being deposited. (Epa.gov) There are several different pollutants that can lead to acid rain such as SO2, SO3, NO2, and CO2. These pollutants react with water to create acids as shown below. Sulfur dioxide + water  sulfurous acid Sulfur trioxide + water  sulfuric acid Nitrogen dioxide + water  nitric acid + nitrous acid Carbon

Title: Oxidation of Benzoin and Rearrangement of Benzil to Produce Benzilic Acid Abstract The objective of the lab was to produce benzilic acid from benzoin. Benzoin was successfully oxidized with nitric acid to form benzil. The percent yield of benzil was 59.26% and the melting point range was 94.1-95.5°C. The literature melting point of pure benzil is 95°C, which indicates the correct product was obtained. Benzil was then rearranged using potassium hydroxide to form benzilic

There are other secondary gases like argon, Helium, nitrous oxide, carbon monoxide and hydrogen used along with the primary MAP gases. MAP packaging helps in extending the shelf-life of the product by inhibiting the microbial growth and maintains the colour of the meat product when compared with the product packaged

Acid Rain Acid rain, to our eyes, is not much different from regular rain, but the contents of that precipitation can be devastating to plant-life and ecosystems. Acid rain is formed in the atmosphere when gases such as sulfur dioxide are oxidized; sulfur trioxide is converted into sulfuric acid by a chemical reaction with water, or when nitrogen dioxide reacts with hydroxide to form nitric acid. The most oxidation reactions are with ozone, hydrogen peroxide, and of course, oxygen. There are

sodium oxide should be and are NaCl and Na2O respectively. Aluminum chloride and aluminum oxide should be and are AlCl3 and Al2O3. When there are multiple oxidation states of a metal, more than one compound is possible. For instance, copper and oxygen form Cu2O and CuO and more information are needed to distinguish between the two. When naming a copper oxide, it is very important that the name distinguish between the two possibilities [copper(I) oxide or cuprous oxide and copper(II) oxide or cupric
