Calculate the molar volume of saturated liquid and the molar volume of saturated vapor by the Redlich/Kwong and the Peng/Robinson equation for the following compounds and compare results with values found by suitable generalized correlations. a) Propane at 70°C where Psat = 25.94 bar. b) Isobutane at 120°C where Psat = 28.53 bar.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
