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 stream of chlorine: 2xi3+3cl2â2xcl3+3i2 if 0.5500 g of xi3 is treated, 0.2596 g of xcl3 is obtained.

When you kick a soccer ball across a field it will eventually come to a stop. Does this prove or disprove Newton's first law of motion? It disproves Newton's first law of motion because gravity is stronger than friction.
