Hi great info - I think maybe one of the Silicon chemical formula is incorrect.

Si + 3HCl = SiHCl3 + H2
SiHCl3 + H2 = Si + 3HCl2


It appears that the second formula does not balance.

From this link, I found a formula that looks better to me:

SiHCl3 + H2 = Si + 3HCl

 

Where did you see the error in the eBook? You can post a link to the chapter, then quote the offending paragraph.
