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 and water: nh3(g)2o2(g)->hno3(g)+h2o(g) Write the net chemical equation for the production of nitric acid from nitrogen, hydrogen and oxygen. Be sure your equation is balanced.
