Chilean Copper Mine Collapse Chilean Copper Mine Collapse A small copper mine in San Jose‚ located in north Chile‚ collapsed trapping workers underground. The mine collapsed on August 5th‚ trapping 33 workers in the mine. The coverage of this mine collapse came two long weeks after the traumatic event. Initially the incident did not catch any news worthy attention. Mine collapses are pretty common but the accident finally caught the interest of an editor‚ and then it went viral from

Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration

Why Production of Plastic Bags Should Banned In the 21st century‚ people have become their own killers. From countryside to the cities‚ the use of plastic materials has greatly increased. In the grocery stores‚ tons of products are packaged using plastic materials. About 30 years ago‚ in countries like Uganda‚ there were no plastic bags used for packaging and carrying items. Items in the shops were packed in biodegradable paper bags. In the markets‚ people used local materials like banana leaves

Lab: STOICHIOMETRY The reaction of Iron with Copper(II) Sulfate Purpose: In this experiment we will use stoichiometric principles to deduce the appropriate equation for the reaction between metallic iron and a solution of copper (II) sulfate. This reaction produces metallic copper‚ which is seen precipitating as a finely divided red power. Materials: Flask beaker Copper solution Balance Hot plate •150 ml beaker •1 gram of iron power
