Answer:
The answer to the question is
The equilibrium partial pressure (atm) of ammonia, assuming that some solid NH₄HS remains 0.26 atm.
Explanation:
To solve the question, we write out the chemical equation as follows
NH₄HS (s) ⇄ NH₃ (g) + H₂S (g)
From the above equation, it is observed that only the gaseous products contribute to the partial pressure
Kp =PNH₃·PH₂S where at Kp = 0.070 and PNH₃, PH₂S are the partial pressures of the gases
However since the number of moles of both gases are equal, therefore by Avogadro's law PNH₃ = PH₂S
Then PNH₃ = √(0.07) = PH₂S = 0.2645 atm. ≅ 0.26 atm.
most prolly option D
Explanation:
NaCl + H2SO4 -> Na2SO4 + HCl[g]
Answer:
Graph E matches description 3 (the car is accelerating).
Explanation:
When the graph increases, the line is turned up (graph E). So when something accelerates, it is going to increase. In this case, it would increase by speed.
Flammmability is a chemical change because it changes the composition of the object. the product is very different from the rectant.
Answer:
Myocarditis = C) Inflammation of the muscular wall of the heart.
Explanation:
Myocarditis is a condition usually caused by a virus.
It causes inflammation within the heart, generally along the muscular wall and within the middle layers.
It's definitely not a great condition. It's possible it could weaken his heart's ability to pump properly, which in turn could effect organs and cause organ failure. It'd lead to intense bouts of pain constantly, swelling, problems breathing, or even heart failure.
