Overview The Bhopal disaster‚ also referred to as the Bhopal gas tragedy‚ was a gas leak incident in India‚ considered the world’s worst industrial disaster.It occurred on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal‚ Madhya Pradesh. Over 500‚000 people were exposed to methyl isocyanate gas and other chemicals. The toxic substance made its way in and around the shantytowns located near the plant.Estimates vary on the death toll.

situation‚ vapours are assumed to be obeying the Ideal Gas Law‚ which is PV = nRT. P is the current atmospheric temperature‚ measured in atmospheres‚ V is the volume of the flask‚ n is the moles of the gas and T is the temperature of the water bath‚ measured in degrees Kelvin (Weisstein‚ 2007). R remains a constant‚ which is 0.08206 L atm/K mol (Weisstein‚ 2007). The equation used to solve for n (mass/molecular weight) is substituted into the Ideal Gas Law and then rearranged in order to solve for molecular

Physical vapor deposition PHYSICAL METHODS A physical deposition process consists of three steps: 1. Emission of the particles from a source 2. Their transport to the substrate 3. The condensation on the substrate Physical vapor deposition a process by which a thin film of material is deposited on a substrate according to the following sequence of steps: 1) the material to be deposited is converted into vapor by physical means; 2) the vapor is transported across a region of low pressure

give oxygen gas. What the chemical equation for the decomposition of sodium chlorate? The purpose of this inquiry-based experiment is to design a small-scale procedure to determine the chemical equation for the thermal decomposition of sodium chlorate. Background: Sodium chlorate‚ NaClO3‚ is a colorless‚ odorless‚ white solid that melts at 248 °C. When heated above 300 °C‚ it begins to lose oxygen. The ultimate products of the thermal decomposition of sodium chlorate are oxygen gas and a white

The Camesia gas pipeline‚ which runs from the amazon‚ over the Andes‚ to the pacific coast has been raising a lot controversy in the past decade with its destruction of the Peru rainforest. It has ruptured 4 times with at least three major spills in the first 18 months since it was constructed in 2004. With 22 indigenous communities living in a state reserve in isolation‚ a contractor by way of helicopter has made contact with these isolated communities and is pressuring them to abandon their ancestral
