The main component of the ore is CuFeS2 (sulfur element 1 2 Price, iron element 2 price). It is the main raw material for industrial copper smelting. it is known that the ore is roasted in the air. (1) the amount of material of 92gCuFeS2 = 92g184g/mol = 0.5mol,According to the atomic conservation, the amount of substances that generate Cu and FeS is 0.5mol, 0.5mol,It can be seen from the conservation of sulfur atoms that the amount of SO2 material = 0.5mol × 2-0.5mol = 0.5mol,In the reaction, only the sulfur valence of SO2 was increased,By-The price increased to 4,Therefore, the amount of transferred electronic substances = 0.5mol X [4-(-2) = 3mol,Therefore, the answer is: 3mol;(2) it can be seen from the process flow,The gas produced by roasting I is SO2,Using magenta solution for inspection,The specific operation is: collect the appropriate amount of gas I into the magenta solution,The magenta solution faded,The heating solution is red,Therefore, the answer is: collect the appropriate amount of gas I into t

What are the seawater aquatic plants used in seawater breeding? 1. Shi Yan,Green algae door,Algae,Shi Yuke,Genus of stone.It is also called cabbage, green vegetables, sea lettuce, green vegetables, Moss vegetables and acrylic cloth,Common seaweed.2. algae with large feathers,Produced in the Philippines, Malaysia, Indonesia and Japan,Feather-like seaweed,Fast growth,But it is not as strong and tough as the twisted algae.Feeding is easy,It is an ideal biological 'filter' for seawater quality '.3. Grape algae,A fast-growing seaweed,Under the right conditions,Within 30 days, the university can be longer than the first grade. in recent years, Japanese people have often used it as salad raw food, but generally coral fish friends use raisins to suck No 3 and reduce the content of No 3 in the cylinder.4. Flame algae,Low requirements for light,And can withstand high temperature,It can still grow normally in a low nutrient environment,And there will be no whitening,More suitable for algae filtration tanks or shelt
