This chemical equation shows the decomposition of nitrogen triiodide (NI3) into nitrogen (N2) and iodine (I2). 2NI3 > N2 + 3I2. The molar mass of NI3 is 394.71 g/mol. The molar mass of I2 is 253.81 g/mol. How many moles of I2 will form if 3.58 g of NI3 is completely decomposed?

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
