This question is about some Period 3 elements and their oxides.
Write an equation for the reaction of phosphorus (P4\text{P}_4P4) with a limited supply of oxygen to form phosphorus(III) oxide (P4O6\text{P}_4\text{O}_6P4O6).
Describe a test you could carry out in a test tube to distinguish between solid sodium oxide and solid silicon dioxide.
State the type of crystal structure shown in silicon dioxide and in phosphorus(V) oxide (P4O10\text{P}_4\text{O}_{10}P4O10).
Explain, in terms of structure and bonding, why silicon dioxide has a much higher melting point than phosphorus(V) oxide.
