Answer:
Keq = 0.217
Explanation:
Let's determine the equilibrium reaction.
In gaseous state, water vapor can be decomposed to hydrogen and oxygen and this is a reversible reaction.
2H₂(g) + O₂(g) ⇄ 2H₂O (g) Keq
Let's make the expression for the equilibrium constant
Products / Reactants
We elevate the concentrations, to the stoichiometry coefficients.
Keq = [H₂O]² / [O₂] . [H₂]²
Keq = 0.250² / 0.8 . 0.6² = 0.217
Answer:
Evaluate.
Explanation:
Analyze first, measure second, then calculate, and finally evaluate.
The material that will be able to pass the cell, would be characterized as being soluble. As in order for them to pass, they would be able to dissolve in one of the layers of the membrane, I believe.
Thank you for posting you question here. I think the question is incomplete. I manage to check the complete question elsewhere:
A 0.0075 V/m electric field creates a 3.9 mA current in a 1.0 mm diameter wire. What is the wire made of?
<span>a) Aluminum (resistivity: 2.82 * 10 ^ -8) </span>
<span>b) Nichrome (resistivity: 1.1 * 10 ^ -6) </span>
<span>c) Copper (resistivity: 1.68 * 10 ^ -8) </span>
<span>d) Iron (resistivity: 1.0 * 10 ^ -7)
</span>
the answer is B which is Nichrome (resistivity: 1.1 * 10 ^ -6)
