Consider a binary mixture for which the excess gibbs energy is given by gfirt 2.1xjx2 (xi + 2x2). for each of the following overall compositions, determine whether one or two liquid phases will be present. if two liquid phases will be present, find their compositions and the amount of each phase present (phase fractions) (a) z0.2 (b) = 0.3 (c) zi= 0.5 (d) z,-0.7 (e) z1-0.8

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.  

i believe the answer is 5,000
