Acyclopropane-oxygen mixture is used as an anesthetic. if the partial pressure of cyclopropane, n the mixture is 330 mm hg and the partial pressure of the oxygen is 1.0 atm, what is the total pressure of the mixture in torr?
a) 1100 torr
b) 430 torr
c) 1.4 torr
d) 760 torr
e) 330 torr

A) 1100 torr

Explanation:

given values 760mm=1atm

add 273 to get kelvin to degree

Pressure total  Pt = P a + P b  (total pressure for all and molecules  )

so that being said

Pressure total = Pcyclopropane  + P Oxygen

= 330 mm Hg + 760 mm Hg

= 1090 mm Hg

so round about 1100 torr

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.
