Answer:
a)decanting,filtering,and evaporating.
In a solid, atoms are packed very closely together, almost like an organized grid. They vibrate, and rub against each other, but stay in the same place.
In a liquid, atoms are farther apart, and slide around each other, which is why if you pour water on the ground, it won't stay in any specific shape unless it is in a container. However it does stay together. Gas on the other hand is very spread out with a lot of space in between the individual atoms. All the space allows gases to expand and contract. Gas atoms bounce around, and will not hold a form or stay together.
Answer: - 5.00 kJ
Explanation:
1) The heat evolved during the reation is proportional to the number of moles dissolved.
2) Proportionality = ratio is constant
<span>3) δh°soln of HNO3 is –33.3 kJ/mol => ratio 1
-33.3 kJ
ratio 1 = ---------------------
1 mol HNO3
4) ratio 2
x
--------------
0.150 mol
</span>
5) proportion
ratio 1 = ratio 2
x -33.3 kJ
--------------- = -------------- => x = 0.150 mol * (-33.3kJ) / 1 mol = - 4.995 kJ ≈
0.150 mol 1 mol
≈ - 5.00 kJ
The equilibrium constant, k of the reaction in which case, the concentrations of the given reactants and products are as indicated is; Choice A; K = 3.1 x 10⁵
<h3>What is the equilibrium constant , k of the reaction as described in the task content?</h3>
It follows from above that the concentrations of the reactants and products are as follows; [H2] = 0.10 M, [N2] = 0.10 M, and [NH3] = 5.6 M at equilibrium.
Hence, the equilibrium constant of the reaction in discuss is;
K = [5.6]²/[0.10]³[0.10]
k = 5.6² × 10⁴
k = 3.136 × 10⁵
K = 3.1 × 10⁵.
