Please Help - Chemistry Problem! one of the steps in the commercial process for converting ammonia to nitric acid involves tha catalytic oxidation of NH3 to NO: 4NH3(g) + 502(g) -> 4NO(g) + 6H2O(g)

How many grams of NO are formed by the complete reaction of 2.50 g of NH3?

it's filtration, but this is an assumption so my apologies if i got this

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
