Produces CO (carbon monoxide) which reduces iron-oxide to Iron. LASTLY‚ LIMESTONE Limestone (calcium remove impurities. carbonate) is used to When the metal is melted‚ limestone combines with impurities and floats to the top of the metal‚ forming slag. The slag can then be removed‚ purifying the iron. Ferrous alloys can be broadly classified

Acetylene Gas A 600 ml beaker was approximately half filled with water. A test tube was completely filled with water. Test tube was covered with thumb and was turned upside down under water in the beaker. Tweezers were used to drop one piece of calcium carbide into the beaker and was quickly covered with the test tube to collect any gas produced. When the test tube was half full of gas‚ the test tube was lifted out of the water and the inverted test tube was set on the lab bench. The procedure was repeated

BHOPAL GAS TRAGEDY AND ITS ETHICAL ISSUES SUMMARY Bhopal Gas Tragedy was a gas leak incident in India‚ considered one of the world’s worst industrial catastrophes. It occurred on the night of the last year of 1984 at the Bhopal Union Carbide Corporation (Union Carbide India Limited – UCIL) pesticide plant in Bhopal‚ Madhya Pradesh‚ India. A leak of methyl isocyanides gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people. It also causes environmental issues
