3 these are 5,6&7 are the significant
Answer:
NaCl will only conduct electricity in solutions
Explanation:
For electrical conduction, free mobile electrons as seen in most metals must be present or ions which are charged particles must be available for solutions and molten substances.
- Sodium chloride is an ionic compound without free mobile electrons or ions despite being ionic.
- It will maintain a subtle and unique charge stability when in solid form.
- In solid, the ions are not free to move and remain locked up in the solid mass.
- When introduced into a solution, the ions becomes free to move and this will aid electrical conduction.
Answer:
Through their adaptations from their habitat; environment
Explanation:
Charles Darwin explains evolution and their genetic material evolves during the process. For example, fruit birds have narrow bills whilst seed-eating birds have big bills. The foods they eat forced their DNA to adapt with the system in order to survive.
