Question

According to the following balanced reaction, how many moles of NO are formed from 2.50 moles of NO2 if there is plenty of water present?

​3 NO2(g) + H2O(l) →  2 HNO3(aq) + NO(g)

Answer 1

- Ans buiven Reaction is :- | 3 NO240) + 142012) - 2 HNOzlag) + NOGO Vaing Strichio metry which states that the coefficient represent the mole of the substance, in a balanced reaction . In the above balanced reaction 3 moles of NO₂ (g) reacts completely with 1 molo. H₂O (f) to produce 2 moles of HNO (aq) and 1 mole Nolg) Hence it implies that 3 moles NO₂(g) produces I mole No (g) -

2 1 mole Noig) produces 1 mole No lg) Hence - 2050 mole No 19) produces 1x2.50 moles No (q) = 1 x 2.5 mole - Hence formed = 0.833. moles 0.833 moles No (g) is from 2050 moles No₂lg)
