Liquid méthyl ethyl ketone (mek) is introduced into a vessel containing air the system temperature is increased to 55 0, and the vessel contents reach equilibrium with some mek remaining in the liquid state. the equilibrium pressure is 1200 mm hg (a) use the gibbs phase rule to determine how many degrees of freedom exist for the system at equilibrium. state the meaning of your result in your own words. (b) mixtures of mek vapor and air that contain between 1.8 mole% mekand 11.5 mole% mek ignite and burn explosively if exposed to a flame or spark. determine whether or not the given vessel constitutes an explosion hazard

what are the choices?

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
