Question

Nitrogen reacts with hydrogen to give Ammonia calculate the volume of the ammonia gas formed when nitrogen reacts with 6 litres of hydrogen all volumes measured at STP

Answer 1

Reaction will be this     N₂ + H₂ → NH₄
Balance the equation   N₂ + 4H₂→ 2NH₄
let 4H2 be na and 2nh4 be nb,
                na/4=nb/2
⇒ 6/22.4/4=x/22.4/2
⇒ 6/4=x/2
⇒x=3
ammonia will be produce 3 litre at stp
