A. Predict if entropy would increase or decrease during the following phase changes. (2 points)

i. H2O(g) H2O(l) (1 point)

ii. H2O(s) H2O(l) (1 point)

b. Predict whether the entropy would increase or decrease in the reaction KCl(s) K+(aq) + Cl–(aq). Explain your answer. (2 points)

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the answer is a for sure mark brainliest i had got this right on usatestprep

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.
