Answer:
An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water. ... A substance that dissociates into ions in solution acquires the capacity to conduct electricity. Sodium, potassium, chloride, calcium, magnesium, and phosphate are examples of electrolytes.

Answer:
0.492 J/g °C
General Formulas and Concepts:
<u>Thermodynamics</u>
Specific Heat Formula: q = mcΔT
- <em>q</em> is heat (in J0
- <em>m</em> is mass (in g)
- <em>c</em> is specific heat (in J/g °C)
- <em>ΔT</em> is change in temperature (in °C)
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] <em>q</em> = 45.0 J
[Given] <em>m</em> = 8.10 g
[Given] <em>ΔT</em> = 24.3 °C - 13.0 °C = 11.3 °C
[Solve] <em>c</em>
<em />
<u>Step 2: Solve for </u><em><u>c</u></em>
- Substitute in variables [Specific Heat Formula]: 45.0 J = (8.10 g)c(11.3 °C)
- Multiply: 45.0 J = (91.53 g °C)c
- Isolate <em>c</em>: 0.491642 J/g °C = c
- Rewrite: c = 0.491642 J/g °C
<u>Step 3: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs.</em>
0.491642 J/g °C ≈ 0.492 J/g °C

Answer:
Arranged in order of most soluble to least soluble in water:
![KCl > CH_{4} > C_{4} H_{9} OH > C_{3}H_{8}](https://tex.z-dn.net/?f=KCl%20%3E%20CH_%7B4%7D%20%20%3E%20C_%7B4%7D%20H_%7B9%7D%20OH%20%3E%20C_%7B3%7DH_%7B8%7D)
Explanation:
Water is a polar solvent due to the electric charge it possesses. Hence it would only dissolve polar molecules.
Non-polar molecules would be dissolved by non-polar solvents.
Short chain alcohols are more soluble than butanol, but generally the polar -OH group is soluble in water.
