a.) Ionisation energy is the energy required to remove the most loosely bound electron from an element.b.) Ionisation energy decreases down a group due to increasing electron shielding, this decreases the...

If you increase the pressure the equilibrium tries to reduce it and moves to the direction of fewer gas molecules.
If you decrease the pressure, the equilibrium moves to increase it and moves where ...

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 ...

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...

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...
