mass. In addition to gravimetric analysis‚ it is a method based on the isolation of the desired constituent in pure form or in some combined form from a sample‚ and weighing the isolated constituent. Similarly thermal decompositions institutes similar components. Thermal decomposition is a method for hydrates to commonly lose all or part of their water when heated. We used this method to decompose Cobalt Oxalate Hydrate into Cobalt Oxalate. Then we calculated the mass of Cobalt by using the molar ratio

The War in Afghanistan (2001–present) refers to the intervention by North Atlantic Treaty Organisation (NATO) and allied forces in the ongoing Afghan civil war. The war followed the September 11 attacks‚ and its public aims were to dismantle al-Qaeda and eliminate its safe haven by removing the Taliban from power. U.S. President George W. Bush demanded that the Taliban hand over Osama bin Laden and expel al-Qaeda. The Taliban requested that bin Laden leave the country‚ but declined to extradite

The Roots of Pakistan’s Political Crisis. Sadia Abbas It seemed too good to be true. Pakistan had a judiciary asserting itself. The media was feeding a nascent democracy movement. The military was being challenged. Even the intelligence services were being asked to produce those it had been “disappearing” for years. If you were accustomed to CNN quiescence and had grown up in a Pakistan with one state channel on which hyper-formal anchor-people mechanically read the news in an Urdu inaccessible to

Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde

Because of its versatility as well as ease of extraction and transportation‚ oil could be termed as; number one fossil fuel. It is a combustible thick‚ black liquid hydrocarbon which is formed within the earth crust because of millions of years of decomposition (under high pressures and temperatures) of plant and animal matter (Cleveland‚ 1992). Coal Coal can be defined as; the most abundant as well as cheapest available fossil fuel of planet Earth and it is formed via ferns‚ plants and swamp remains

We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: 2 H202 (aq) 4 2 H20 (l) + 02 (g) We can trap the

Nitrogen‚ as it stimulates plant root growth and the uptake of other nutrients. Most nitrogen is derived from the decomposition of organic matter and nitrogen fixation by bacteria. My soil will also be abundant in Phosphorus to enhance photosynthesis‚ nitrogen fixation‚ flowering‚ fruiting‚ and seed production. It also encourages root development. The main source of phosphorus is the decomposition of organic matter. Potassium will be my third main ingredient as it is known to activate 80 enzymes responsible
