Consider a binary liquid mixture with the following two-parameter margules equation values: a12 = 1.2; a21 = 3.0. using the double-tangency method, determine if the system (defined by its margules equation parameter values) exhibit a miscibility gap (i. e., split into alpha and beta phases). if so, identify the composition of the coexisting phases. select one: a. x1alpha = 0.18, x1beta = 0.78 b. x1alpha = 0.32, x1beta = 0.94 c. x1alpha = 0.12, x1beta = 0.94 d. x1alpha = 0.45; x1beta = 0.65 e. the solution cannot split into two phases

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
