When attempts are made to extinguish magnesium fires with water, magnesium aggressively reacts with hydrogen gas. Zeolite A increases the amount of sludge. Nature, however, has found a much more elegant way: plants use the ability of many bacteria to bind the nitrogen from the air with the help of a sophisticated enzymatic reaction. Doing this every morning can snap back sagging skin (no creams). Finally, we let the mass cool down well. The question remains why the pile is strangely stratified after burning: the white oxide is clearly visible on the outside, the yellow-gray nitride on the inside. The balanced equation for this reaction is: Mg, N2 (s) + 6H2O(1) 3Mg(OH)(aq) + 2NH3(aq) If 3 moles of magnesium nitride react. Magnesium nitride (Mg3N2) reacts with warm water (6H2O) to give ammonia (NH3) and magnesium hydroxide. However due to existing hydroxyl ions in the aqueous solution, solution will become basic. We’ll add some water to the sample. Personalized courses, with or without credits. 3. ... Q: Question 1 That was an expensive process, since magnesium had to be obtained beforehand by electrolysis!
