Nitrogen oxide

produce a product of 75% silica (SiO2) and 25% sodium oxide (Na2O). This mixture will melt and fuse at a much lower temperature of 800°C. Unfortunately, the glass produced with this composition is water-soluble which is also known as water glass. This is not suitable for glass bottle since it need to contain water so, to stabilise the glass, other chemical substance is mixed into the composition such as calcium oxide (CaO) and magnesium oxide (MgO). The chemical mixtures are obtained by the addition

“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

simply put, is a mixture of rainwater and a few specific chemicals that are emitted both naturally and non-naturally. The process occurs in the lowest layer of the atmosphere, the troposphere. When compounds such as sulfuric dioxide(SO2) and nitrogen oxides(NO, NO2), are transported to this layer and react with the other parts of the troposphere(water, oxygen, carbon dioxide). Acid rain was first discovered in Sweden in 1872, but has been seen as a more prevalent problem in modern times. Although

Determining the Empirical Formula of Magnesium Oxide Post Lab Introduction: The purpose of this experiment was to determine the empirical formula of magnesium oxide. Empirical formula can be defined as “the formula of a compound expressed as the smallest possible whole-number ratio of subscripts of elements in the formula”. We were also required to determine the percentage yield of all trials. Percentage yield is the ratio of the actual yield to the theoretical yield, expressed as a percent, and

ABSTRACT This report is written to explain about acid rain in detail which is one of the hazardous effects of industrialization around the planet. The main causes and their contribution in increasing this curse for flora, fauna and humans. Further, this report describes various factors and it scrutinises the data not only of its adverse effect but also of gases’ amount which consequently make acid rain with water molecules. At the end, report ends up explaining methods to control this and solutions

such as sulfur dioxide 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

Chemistry Mrs. Wright Block 2 The Determination of the Chemical Formula of Magnesium Oxide Conclusion The purpose of this lab was to find the empirical formula of magnesium oxide. The empirical formula of a compound is the simplest formula based on the number of different atoms in that compound. In this lab, the student burned magnesium, in the form of a ribbon, which bonded with oxygen to form magnesium oxide. The mass of oxygen was calculated by subtracting the mass of the magnesium ribbon from

rain is “’rainfall made so acidic by atmospheric pollution that it causes environmental harm, chiefly to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulphur and nitrogen oxides which combine with atmospheric water to form acids.” In Northern Europe and North America millions of trees have died because of the causes of acid rain. Some lakes contain so much acid that all the fish have died and the birds that relied on

metabolized through the gastrointestinal tract. After conversion of nitrites to nitric oxide it is absorbed via the small intestine where it is distributed into circulation. Once the nitrites and nitric oxide enter the circulatory system it reaches target tissues where it may be used for cellular activity. It is found that 25% of nitrites are concentrated in the salivary

Proximate Analysis In proximate analysis of the coal the moisture content, ash, the volatile matter, and the fixed carbon in the coal sample is determined. It is the most common simplest form of coal evaluation. Moisture Moisture occurs in Various forms Within the Coal: Surface or Free Moisture: the moisture produced on the surface of coal particles Or Inherent Moisture: the moisture produced by capillary action within the pores of coal. Decomposition Moisture:
