Is best inexpensive robot vacuum tested before shipment?
Water purifier can not filter out minerals when purifying water? Are you referring to minerals as salts?Mineral salt?Most mineral salts are dissolved in water,To get from the liquid,Remove the liquid.Then use the RO film or filter technology.If you don't have these technologies in your water purifier filtration principle,It's hard to get rid of minerals.The water purifier uses tap water as the source water,Through the membrane filtration principle,Will filter out the various minerals needed by the human body in tap water,The water produced is close to pure water.The reverse osmosis technology is used for domestic drinking water purification equipment to pass raw water through fine filters, granular activated carbon filters, compressed activated carbon filters, etc,Then pressurize through the pump,The pore size is 1/10000 μm (equivalent to 1/6000 of the size of E. coli,Reverse osmosis membrane (RO membrane) of 1/300 of the virus ),Make the higher concentration of water into the lower concentration of water,

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
