Answer:
C.it has a lower melting temperature
Explanation:
A good way to solve this problem may be to think about a simple ionic compound, such as salt, NaCl:
- NaCl easily disolves in water, so options A and B are true about ionic compounds.
- Salt powder does not conduct electricity, however a concentrated solution of salt in water does. Meaning that option D is true as well.
- NaCl has a melting point of 801 °C, not particularly a low value. Thus the correct option is C.
Chemicals are found in all things. Solids, liquids, and gases.
