The purpose of this lab was to find out the reaction of iron nails and CuSO4‚ copper sulfate solution. Before starting the experiment‚ there were two possible outcomes of the reactions. CuSO4 + Fe → FeSO4 + Cu or 3CuSo4 + 2Fe → Fe2(SO4)3 + 3Cu. The ion chart showed that iron can only make two charges‚ +2 and +3. As the liquid evaporated‚ the weight changed because the liquid added to the nail’s weight. In a real world situation‚ scientists can use ratios to determine how much of a substance that

IRON ORE DRY BULK TRADE Demand for dry bulk commodities like iron ore is driven by industrial production and growth requirements. An increase in steel production stimulates the growth of iron ore shipments and also the trade. From early 2000s‚ the iron ore market began a transformation following China’s increasing demand for steel. World production of iron ore exceeded 1 billion tonnes in 2002. International iron ore trade reached record levels at 512 million tonnes (Mt). Price negotiations
