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 N2 g + 3H2 g → 2NH3 g In the second step, ammonia and oxygen react to form nitric acid HNO3 and water NH3(g) + 2 O2(g)→HNO3(g) + H2 O(g) Write the net chemical equation for the production of nitric acid from nitrogen, hydrogen and oxygen. Be sure your equation is balanced.
