Answer:
A buffer is most resistant to pH change when [acid] = [conjugate base]
Explanation:
My best bet is A
69,57% + 30,43% = 100%
100% ----------- 92,02g
69,57% oxygen ----- x
x = 64,004 ≈ 64,00g oxygen
100% ---------- 92,02g
30,43% nitrogen ----x
x = 27,99 ≈ 28g nitrogen
Mass of oxygen = 16g
Mass of nitrogen = 14g
moles of oxygen = 64g : 16g = 4
moless of oxygen = 28g : 14g = 2
N : O
4 : 2 ||:2
2 : 1
empirical formulas = N₄O₂
molecular formulas = N₂O
N₂ + ¹/₂O₂ ---> N2O
