An ionic compound like salt (sodium chloride) would likely create the most conductive solution, as it dissociates into positive and negative ions when dissolved in water, allowing for the flow of electrical charge.
Sodium chloride, NaCl, for example is of neutral pH and conductive in solution or in molten state. It is a salt.
The substance likely forms ionic bonds because ionic compounds are typically water-soluble, conductive in solution, and can form hard structures. These bonds form between a metal and a non-metal, resulting in the transfer of electrons from one atom to another.
It is more likely to be called a precipitate.
To create a more concentrated solution, you can add more solute (substance being dissolved) to the solvent (liquid medium). This increases the amount of solute particles in the solution, making it more concentrated. Alternatively, you can decrease the amount of solvent in the solution, which also increases the concentration of the solute.
The substance that appears at the bottom of the evaporating dish after heating likely came from the dissolved solute in the solution that was being evaporated. As the solvent evaporates, the solute becomes more concentrated and eventually crystallizes or precipitates at the bottom of the dish.

An electrolyte is a substance that conducts electricity when dissolved in water. To determine if a substance is an electrolyte, you can test its ability to conduct electricity in a solution. If the substance allows electric current to flow through the solution, it is likely an electrolyte.
The yellow solid separated out is likely to be elemental iodine (I2). When substance X is added to potassium iodide solution, a redox reaction occurs leading to the formation of iodine, which appears as a yellow solid.
The likely word is solution (one substance dissolved in another, usually a liquid).
Ammonium hydroxide is conductive because it dissociates into ammonium ions (NH4+) and hydroxide ions (OH-) in water. These ions are free to move and carry electric charge, allowing the solution to conduct electricity.
It is more likely to be called a precipitate.
The substance is likely a base, as bases typically lead to an increase in pH when added to a solution. Bases are substances that can accept protons or release hydroxide ions, causing the solution to become more basic.
If the solid substance is nonpolar, it will more likely dissolve better in an organic solvent rather than water. In this case, using distilled or tap water to prepare a solution may not make a significant difference in the solubility of the substance since it is nonpolar and not likely to dissolve well in water regardless.

Dissolved minerals such as calcium, magnesium, and potassium are most likely to be carried by streams in solution. These minerals are often derived from weathering of rocks and are transported by streams as they flow through the landscape.
