20212 -202 A blast furnace makes pig iron containing 3.2% and 1.8% of Carbon and Silicon and remaining as Iron respectively. The ore is a combination of 80%, 12% and 8% of Iron Oxide, Silica and Aluminum Oxide respectively. The process requires coke at a rate of 1 Kg per kg of pig iron produced. The coke is adulterated with Silica with 10% of silica and remaining to be carbon. The flux is obtained at a rate of 0.4 kg per kg of pig iron and is the base of one tonne of pig iron containing pure Calcium carbonate. The blast furnace gas has 30% CO and 15% CO2. calculate the following assuming the 1. The weight of core used. 2.

Mganga is doing a routine analysis in a copper plating factory. He is regularly making up solutions of verypure CuSO4.5H2O. He suspect that a batch of a reagent used to make up a stock solution of CuSO4.5H2Ois impure and it may contains some CuCl2. He asked you to determine the percentage impurity as follows:Dissolve1.500g of a mixture and make up to 1.00L mark.150mL of this solution was treated with 20.00mLof 0.100M AgNO3 to remove 98.6% of chloride as AgCl precipitate.
