(if) Will any of the two reactants remain unreacted? (iii) If yes, which one and what would be its mass? 25 • How are 0.50 mol NazCOa and 0.50 M NazC03 different? If ten volumes of dihydrogen gas reacts with five volumes of dioxygen gas, h many volumes of water vapour would be produced? Convert the following into basic units: (i) 28.7 pm 15.15 pm 25365

N₂ + 3H₂ -------> 2NH3

1 mol + 3 Mol = 2 moles

No. of Moles of N₂ = 206/28 = 7.35
No. of moles of H₂ = 103/2 = 51.5

From the reaction,
7.35 moles of N₂ will react with (7.35x3) = 22.05 M of H₂

Thus, H₂ is in excess.

a) Mass of N₂ + Mass of H₂= 206 g + (22.05 x2) = 206 + 44.1 = 250 g of ammonia
b) H₂ remains unreacted
c) Mass of unreacted H₂ = (51.5 - 22.05) X 2 = 58.9 g
