1. The student should draw the lewis structure - this should be worked through using the whiteboard 2. From the lewis structure it can be identified that NH3 has 3 bonds and one lone pair of electrons ...

Kc=[Cl2(g)][PCl3(g)]/[PCl5(g)] for this reaction. The rate constant is not affected by changes in concentration and hence an increase in the concentration of Chlorine causes an increase in the concentrati...

A negative enthalpy change represents an exothermic change where energy is released from the reaction, a positive enthalpy change represents an endothermic reaction where energy is taken in from the surro...

The smaller ion of the two would be Mg²⁺. Both ions have the same electronic arrangement so the amount of shielding occuring for both ions is the same. The key difference between the ions that ...

A Born-Haber cycle shows how one mole of an ionic lattice is formed from its elements in their standard states and their standard conditions. You start with the elements in their standard states, and at e...
