Nitric acid is often manufactured from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming of natural gas, in a two-step process. In the first step, nitrogen and hydrogen react to form ammonia: N,(g)+3 H,(g)→2 NH,(g) In the second step, ammonia and oxygen react to form nitric acid and water: NH3(g)+20,(g)→HNO,(g)+H,O(g) Write the net chemical equation for the production of nitric acid from nitrogen, hydrogen and oxygen. Be sure your equation is balanced.
