Answer:
I believe the organelle should replace the question mark!
Mixture is obtained when several different substances are mixed together. The mixture can be separated back into its original substances and this is what differs them from compounds. From the given option, the following defines the mixtures:
<span>C. Substances that are combined but do not chemically react. </span>
<span>The answer is A. The pump and the plastic are the only ones that create pressure compared to the other choices.
When you exert a force on the pump to a closed object such as plastic, the pressure inside the pump that it gives off makes the plastic full of air. Pressure is defined to be the force per unit area or the stress within a fluid. </span>
Answer:
Kp = 0.0146
Explanation:
We can solve this equilibrium problem using an ICE Table. There are 3 stages: I(Initial), C(Change) and E(Equilibrium). Only <em>gases</em> and <em>aqueous species</em> participate in the equilibrium.
NH₄CO₂NH₂ ⇄ 2 NH₃(g) + CO₂(g)
I 0 0
C +2x +x
E 2x x
<em>Total gas pressure is equal to the sum of partial pressures at equilibrium.</em>
pNH₃ + pCO₂ = 0.463 atm
2x + x = 0.463 atm
3 x = 0.463 atm
x = 0.154 atm
Then,
pNH₃ = 0.308 atm
pCO₂ = 0.154 atm
We can replace this data in the Kp expression.
