Report’s Newmont that no contamination of the fish or the water was happened. In 2004‚ Newmont Minahasa Raya (NMR) began closing down its operations in North Sulawesi‚ leaving local communities in Buyat Bay and Ratatatok with a dubious legacy. NMR use a submarine tailings disposal (STD) system which a method of waste due to its harmful environmental and health impacts. From 1996 until its closure‚ NMR dumped more than four million tons of mine waste into the bay. Forum the Environment (WALHI) found that

In the13C NMR‚ there were 5 peaks‚ which meant that there were five different non-equivalent carbons. With this information‚ it can be deduced that the compound does not have a methyl group attached to a four-carbon chain because the methyl carbon and the first carbon on the chain would be equivalent. This would result in an 13C NMR with 4 peaks‚ so the compound would need to have a five-carbon chain. With the assumption

graduate courses at the University of Pittsburgh for free where he later received his PhD degree in 1962. During his studies‚ he learned about nuclear magnetic resonance (NMR). Then he was drafted into the Army from 1954-1955 then left to work at the State University of New York at Stony Brook. He realized new images could be made from NMR. Lauterbur’s breakthrough idea was to vary the strength of the magnetic field over the object which in turn emitted various radio waves that could be turned into images

Introduction PT Newmont Minahasa Raya (NMR) is a joint venture company between Newmont Gold Company (USA)‚ which owns 80 percent of the shares‚ and PT Tanjung Serapung (Indonesia) holding 20 percent. PT. NMR is located in South East Minahasa‚ some 80 km south of Manado‚ the capital of North Sulawesi. PTNMR operated an open pit mine from 1996 and ceased operations in 2001 after the deposit was recovered . They started producing gold in 1996 and began dispose their whole tailings through the pipe

of 6M hydrochloric acid was added in 5ml increments until the solution had a pH lower than 2. The flask was swirled for 3 minutes and then vacuum filtered for about 3 minutes. The product was then weighed and the percent yield was calculated. The H NMR was then obtained for this product‚ the remainder of the product was used to run the IR spectrum. However‚ since there was a fire alarm for this lab‚ we were not able to obtain the IR spectrum of our product. Also‚ the solution was not filtered

The percent yield of the product was found to be 49% with six NMR shifts at 1.76‚ 2.14‚ 3.83‚ 6.98‚ 7.53‚ and 7.97 ppm. The melting point was originally found to be 169.7-180.1 °C but was determined to be an error. Introduction: In this experiment an acetophenone is treated with Sodium hydroxide to produce an enolate
