Explain why giant ionic lattices can conduct electricity when molten or in solution rather than as a solid.

In the solid phase the ionic lattice has no mobile ions as all the ions are fixed in place. However when dissolved in a solution or in the molten phase, the ionic lattice breaks down allowing the ions to ...

How do you know whether a compound is ionic or covalent and how can you find the conductivity rate for both heat and electricity?

As a general rule metals bind to non-metals ionically, and non-metals to non-metals bind covalently. For example NH3 is covalent, vs NaCl is ionic. Conductivity rates for electricity are in general depend...

How does increasing/decreasing temperature affect the equilibrium position of the following reaction: CuSO4.5H2O(s) ⇌ CuSO4(s) + H2O(l) ?

The endothermic and exothermic reactions should be identified. Note: if the forward reaction is endothermic, the reverse reaction will be exothermic with the same ΔH but opposite values.In this example: t...

Describe and explain the similarities and differences between the structures of diamond and graphite.

Diamond and graphite are both allotropes of carbon. This means they are both made up of carbon atoms arranged differently and exist in the same physical state. They both have a giant covalent structure.Di...
