Answer:
There is None
Explanation:
This is because it is a derived function dependent on other factors.
Answer:
<em><u></u></em>
Explanation:

<u>1. Dissociation equation</u>
<u />
Assuming 100% dissociation, the equation is:
- Ba(C₂H₃O₂)₂ → Ba²⁺ + 2C₂H₃O₂⁻
↑
acetate ions
<u>2. Molarity</u>
<u />
Calculate the molarity, M, of the solution:
- n = mass in grams / molar mass
- n = 69.g / 255.415g/mol = 0.27015 mol
- M = 0.27015mol / 0.970liter = 0.27850 mol/liter ≈ 0.28M
<u>3. Acetate ions</u>
From the chemical equation, 1 mol of dissolved Ba(C₂H₃O₂)₂ produces 2 acetate ions in solution.
Thus, 0.28 mol/liter × 2 = 0.56 mol/liter = 0.56M ← answer
In order to see which species has the strongest dispersion forces, you need to calculate their molar mass, because the higher the molar mass, the stronger the dispersion forces.
Since E. C8H18 has the highest molar mass, its dispersion forces are also the strongest ones.
Option A. Kidneys.
Excess water, salt, uric acid and other chemicals are wastes that kidneys filter and discard through urine.
Mixture is a combination of two or more substances. The components of the mixture are not chemically reacted and can be separated using physical means.
compound is a combination of two or more substances that are chemically reacted or bound together. The components of the compound cannot be separated except by chemical reactions.
