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.

We calculate for the number of moles of water given its mass by dividing the given mass by the molar mass.
n water = (36.04 g) / (18 g/mol)
n water = 2 mols
From the given balanced equation, every 6 moles of water produced will require 7 moles of oxygen.
n oxygen = (2 mols H2O) x (7 moles O2 / 6 moles H2O)
n oxygen = 2.33 mols O2
Answer:
Intermolecular forces (IMF) (or secondary forces) are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics.

It is true.
