Given a sample of three unknown solids, we would be able to deduce which are ionic solids by their melting and boiling points, conductivity in water, and the insulation they provide.
<h3>What are Ionic solids?</h3>
- An ionic solid is a solid formed by ionic bonds.
- They are the solid version of ionic compounds, which are held together by strong electrostatic energies.
<h3>What properties do they possess?</h3>
- Among their many properties, ionic solids possess high melting and boiling points.
- These solids are also known to conduct electricity well <em><u>when </u></em><em><u>dissolved </u></em><em><u>into </u></em><em><u>water</u></em>, however, this can be tested after melting them as they <u>will not conduct electricity in a solid state</u>.
- A final property that we can use to identify them is that they provide a good means of insulation.
- Each of these properties can be tested and will allow us to determine the ionic solids amongst the samples.
Therefore, we can find the ionic solids amongst the samples by testing their melting and boiling points, conductivity in water, and the insulation they provide, given that each of these should provide high values to indicate an ionic solid.

Answer:
if the value of volume doubles but the mass stays the same, the value for density will be 1
The mass of an ink pen is constant no matter what instrument you use. If you weigh the ink pen on a simple platform balance, it would weigh <em>approximately 16 grams</em>. To measure this mass using a triple beam balance, follow these instructions:
1. Empty the pan, then move the three sliders on each of the beams to left ton the zero mark.
2. Place the ink pen on the pan. As a result, the beams are no longer on the zero mark. Slide the beams until the pointer is at zero.
3. To read the weight, add all the numbers in the three slider beams.
