The correct statement among the following is: 

Nitric acid is manufactured by the Ostwald process, in which nitrogen oxide reacts with water. $$3NO_3(g)+H_2O(l) \rightarrow 2HNO_3(aq)+NO(g)$$How many grams of nitrogen dioxide are required in this reaction to produce 25.2 g of $$HNO_3$$?

In the preparation of $$HNO_3$$ by Ostwald process ammonia is: 

In Ostwald's process for the manufacture of nitric acid, the first step involves the oxidation of ammonia gas by oxygen gas to give nitric oxide gas and steam. What is the maximum weight of nitric oxide that can obtained starting only with 10.00g of ammonia and 20.00g of oxygen?

Nitric Acid is manufactured by:

In ostwald process of manufacturing of $$HNO_3$$ , catalyst used is

Ammonia is produced when a mixture of ammonium chloride and substance X is heated. What is substance X?

When we inhale helium gas funny sound appear which is due to:

Large scale manufacturing of nitric acid by the Ostwald process utilizes the reaction-

The catalyst used in the manufacture of $$NO$$ by Ostwald's process is:
