Zinc is the member of the first row transition series of elements, consisting of Sc, Ti, Cr, Mn, Co, Ni, Cu, Zn, Cd and Hg. All these elements belong to group 12 of periodic table. Zinc has an atomic number 30, an atomic mass of 65 and one main oxidation state (+2). Zinc has five nature isotopes . Zinc is the 24th most abundant element in the earth’s crust. Its properties is very similar to Cd.Zinc is very useful in biological systems. Zinc also is involved in many biochemical processes that…

Different technologies are available for the treatment of gaseous streams containing VOCs (Volatile Organic Compounds), namely catalytic or homogeneous combustion, absorption, adsorption, etc. The goal is either to recover the VOCs, or to destroy them, thus avoiding, in both cases, their emission into the atmosphere. The treatment of “lean” streams, where the concentration of the VOCs is particularly low (e.g. lower than 1% v/v), is a particularly challenging case study as the low concentration…

A benefit versus cost analysis of the United States Coast Guard Oil Prevention Spill program, concluded that efforts to reduce oil spills pays off. Resources allocated to safer working conditions and optimal maintenance suggest that reduced environmental damages could total 3.5 million dollars saved, 1.5 million saved in cleanup costs and approximately 1 million dollars of oil saved. Various ways to prevent oil spillage are the assessment of the technology used in transport and drilling,…

alkane which has been replaced by an –OH group (Chem Guide, 2003).The general chemical formula for alcohols is CnH2n+1OH (BBC, 2014).Alcohols are any of a class of organic compounds characterized by one or more hydroxyl (−OH) groups attached to a carbon atom of an…

Assignment 7 Power Station Emission Aim: The aim of this experiment is to measure the mass of sulphur dioxide in 1m3 of flue gas (waste gas from burning fossil fuels in a power station). To achieve this aim, titration of an unknown solution of sulphuric acid (around 0.2-0.4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator. 1. Introduction Fossil fuel is formed from decayed plants and animals that have been converted to crude…

water’s cycle, the Carbon cycle was more about chemical elements in the ecosystem-atmosphere. Before diving into the subject, to refresh my memory I went back to read book and article to have a good understanding of this cycle. As asserted by Holli Riebeek, carbon is the backbone of life on Earth and mostly all terrestrial beings are made of carbon. Also, carbon was also the fourth largest element in the universe, forged in the heart of dying stars. An article explaining the origin Carbon by…

to be more detailed to incorporate even minor fuel and electricity expenses that were previously treated as miscellaneous expenses. This means that a different accounting department need to be introduced that will account for all aspects involving carbon tax. 2. In future, what other information may be useful to calculate the QEH’s GHG Footprint? Information on company waste disposal outside the company perimeters, employee business travel in vehicles, aircraft not owned by the organization,…

Waste recycling is a process to change renewable waste materials into products in order to prevent waste of useful materials, reduce energy usage, reduce air pollution and also reduce water pollution. It is not unusual to say that if natural resources are recklessly used one day for sure it will come to an end. The countries who are aware of this situation started to apply new preventive methods and implement them directly to stop improvidence, increase life standards and stop the energy crisis.…

in Dunfermline, Scotland, and after Industrialism swept his town, his parents were out of work, causing Carnegie’s family to immigrate to the United States. He taught himself how to read at libraries. He then gradually worked his way up through the steel industry to become one of the most successful businessmen and philanthropists of his time. Carnegie wrote The Gospel of Wealth because as a wealthy man, he felt that he was responsible for filling the void between the rich and the poor with his…

Who: This article is about Carl Scheele a 1700’s chemist. Scheele was born into a very wealthy family and his father was a very smart man. Scheele learned a lot from his father and his friends that would come to teach young Carl. Scheele became a pharmacist which lead him into working with different chemicals. He founded many different acids as well as barium and molybdenum. Scheele also created a green coloring mixture in which is now famous as Scheele’s Green. What: This article is trying to…
