Reaction of silicon with air The surface of lumps of silicon is protected by a very thin layer of silicon dioxide, SiO 2.This renders silicon more or less inert to further oxidation by air even up to about 900 C. After this, reaction with oxygen in the air gives silicon dioxide.
The chlorides of carbon, silicon and lead
2020/8/19· The reaction of lead(IV) chloride with water is just like the silicon tetrachloride one. You will get lead(IV) oxide produced as a brown solid and fumes of hydrogen chloride given off. (This will also, of course, be confused by the decomposition of the lead(IV) chloride to give lead(II) chloride and chlorine gas - see above.)
