An element X forms an iodide (XI3) and a chloride (XCl3) The Iodide is quantitatively converted to the chloride when it is heated in a steam of chlorine.
2XI3+3Cl2-------2XCl3+3I2 I is the iodide X is the unknown substance Cl is chlorine
If 0.5000g of XI3 is treated, 0.2360g of XCl3 is obtained.
A. Calculate the atomic weight of the element X
B. Identify element X
