Ammonia is oxised by oxygen to give nitric oxide and water. The weight of water produced per gram of nitric oxide is `0.1 xx x g`. What is value of x.

In Ostwald's process for the manufacture of nitric acid, the first step involves the oxidation of amonia 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 10.00 g of ammonia and 20.00 g of oxygen?

Metal oxide + acid to X+water, X is

'X' grams of calcium carbonate was completely burnt in air. The weight of the solid residue formed is 28 g. What is the value of 'X' (in grams)

H_(2) gas is often used as a reducing gas. In a particular set up 17.4 gm of MnO_(2) on reacting with excess of hydrogen gas gives water and new oxide Mn_(x)O_(y) such that mass of the oxide obtained is 12.6 g. What will be value of y if x is 2. [Mn=55]
