So, physical properties are what we can detect with our basic 5 senses or measuring tools, and the things that, when changed, dont actually change the chemical properties (like atoms and molecules). Lets take wood for an example: its brown, its solid, it can be big or small, it has a taste and smell, its boiling, freezing or melting point...
Chemical properties, on the other hand, are the things we can change with, for example, experiments and tools. Does it burn? Can it rust/oxidize? How does it react with other chemicals? Is it radioactive, or toxic? All of these are chemical properties you can probably answer.

- Initial velocity=u=0m/s
- Acceleration=a=40m/s^2
- Time=t=2s
- Distance=s

<h2>Answer:</h2>
Low melting points and electrical conductivity in solids are not common properties of ionic solids.
<h3>Explanation:</h3>
In ionic compounds the electrons involved in the bonding are tightly packed under the influence of electrostatic force of attraction. So the movement of these electrons is very difficult.
In the melting point the bond breaking between the atoms is involved. Hence in case of ionic compound there is a high amount of energy needed to break the ionic bonds.
Electrical conductivity involves the free movement of electrons which is impossible in ionic solids.
So low melting points and electrical conductivity in solids are not common properties of ionic solids.
Answer:
30 m/s
Explanation:
Velocity is since we know that the initial velocity is 0, and the acceleration is then we also know that time is 3 seconds it follows that:
