Question 11

This question is about Period 3 elements and their compounds.

1.

Write an equation, including state symbols, for the reaction of magnesium with steam. Explain why this reaction is much faster than the reaction of magnesium with cold water.

[2]
2.

Give an equation for the reaction of sulfur(VI) oxide (sulfur trioxide) with water. Suggest a pH for the solution formed.

[2]
3.

Explain, in terms of crystal structure and bonding, why silicon(IV) oxide has a much higher melting point than sulfur(VI) oxide.

[4]
4.

An element in Period 3 forms an oxide that is insoluble in water. This oxide reacts with both hydrochloric acid and aqueous sodium hydroxide. Give the formula of this oxide, and write a balanced equation for its reaction with hydrochloric acid.
