Debora [2.8K]

Answer:

d) 2.7 mol

Explanation:

  • 3 H2 + N2 → 2 NH3

limit reagent is H2:

∴ Mw H2 = 2.016 g/mol

∴ Mw N2 = 28.0134 g/mol

⇒ moles NH3 = (4.0 moles H2)×(2 mol NH3/3mol H2)

⇒ moles NH3 = 2.666 mol

⇒ moles NH3 ≅ 2.7 mol

givi [52]

Answer:

a) acidic; [H+] = 10^-2.5 = 3 x 10^-3

b) basic; [H+] = 10^-11.7 = 2 x 10^-12

c) slightly acidic (almost neutral); [H+] = 10^-6.8 = 1.6 x 10^-7

d) acidic; [H+] = 10^-3.31 = 4.9 x 10^-4

Explanation:

pH < 7 is acidic; pH > 7 is basic; pH = 7 is neutral

[H+] = 10^-pH
