8. Octane (C2H18) in gasoline reacts with oxygen as shown in the equation below
2CH. + 250,- 16CO2 + 18H1,0
If one gallon of gasoline contains 995 grams octane, what is the volume
of carbon dioxide produced in the combustion of a gallon of gasoline
at STP?
A 69.7 liters
B 179 liters
C 1560 liters
D 178,000 liters

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
