draw,clearly showing the bonding between atoms, the simplest alkane molecule consisting of hydrogen and carbon, describe the molecule shape and bond angles.
At what total pressure of bismuth vapor is the partial pressure of Bi(g) just twice that of Bi2(g) at 1000 K? How many phases are present in the system for this situation?
similarly, what happens if cellulose is reacted with maleic anhydride C4H2O3? Again, how is the cellulose molecule/structure altered and what are the reaction by-products?
