what would life be like if...?

Lets assume there exists a silicon-based life:
#1. what are the most common chemical reactions that we would observe
in a silicon-based life?
#2. What are the candidate substances for getting oxidized or reduced
in order for life to get carried on with?
#3.What are the important building blocks of such life?
#4. What sort of chain could possibly have the same task as a DNA
molecule?
#5. What temperature range would such life sorm at?
Also, could you introduce me to possible book or references which
could further explain this topic ?
Thank you
