Benzene gas (C6H6) at 25-deg C is burned during a steady-flow combustion process with 95% theoretical air that enters the combustion chamber at 25-deg C. All the hydrogen in the fuel burns to H2O, but part of the carbon burns to CO. If the products leave at 1,000K, determine (a) the mole fraction of the CO in the products and (b) the heat transfer from the combustion chamber during the process.

the dissolution of polymer can be thermodynamically described in 2 steps.

  the moles   of   sulfuric acid   that are needed to react   completely with 6.4   moles   of lithium hydroxide   is 12.8   moles ( answer a)

calculation

step 1 : write a balanced   chemical equation

2lioh   + h₂so₄   →   li₂so₄   +2h₂o

step 2 : use the mole ratio   to determine   the   moles h₂so₄

from   equation above   lioh: h₂so₄   is 2: 1 therefore   the moles of h₂so₄

= 6.4   x 2/1   = 12.8   moles   of h₂so₄
