At 25°C, hydrogen iodide breaks down very slowly to hydrogen and iodine: rate = k[Hlf The rate constant at 25°C is 2.4X 10-21 L/mol-s. If 0.0100 mol of HI(g) is placed in a 1.0-L container, how long will it take for the con­centration of HI to reach 0.00900 mol/L (10.0% reacted)?

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change. when the temperature in a room increases from 25°c to 33°c, changes from a solid to a liquid. in a lab, methane and nitrogen are cooled from -170°c to -200°c. the methane freezes and the nitrogen . when gold is heated to 2,856°c it changes from a liquid to a .

In which of these cases are the two wave points considered to be in phase with each other?

Why does his teacher ask him to balance the equation by including the correct coefficient
