Answer:
Kp is 2.98 (option c.)
Explanation:
The decomposition is:
NH₄NO₃(s) → N₂O(g) + 2H₂O(g)
Total pressure at equilibrium is 2.72 bar so, in order to determine Kp we need the partial pressure and we only have total pressure.
According to stoichiometry, nitrogen oxide increase by 1, the partial pressure and water vapor, by 2.
Total pressure is: Partial pressure N₂O + Partial pressure H₂O
2.72 bar = X + 2X → X = 2.72 bar / 3 = 0.91 bar
Partial pressure N₂O = 0.91 bar
Partial pressure H₂O = 1.81 bar
We make the expression for Kp = Partial pressure N₂O . (P. pressure H₂O)²
Kp = 0.91 . 1.81² = 2.98
We do not consider the ammonium nitrate, because it is solid
Answer is: <span>naturally occurring solid, inorganic compound or element is mineral.
Minerals usually have </span>crystalline form, that means than crystal constituents (atoms<span>, </span>molecules <span>or </span>ions<span>) are arranged in a highly ordered microscopic structure, forming a </span>crystal lattice<span> that extends in all directions.

Carbon 13 I believe.
Never heard of an isotope for boron or nitrogen and I know Carbon 12 is the original form of carbon so.. Yeah
