Answer: 1. Water freezing : is -ve.
2. Water evaporating : is +ve.
3. Crystalline urea dissolving : is +ve.
4. Assembly of the plasma membrane from individual lipids: is -ve.
5. Assembly of a protein from individual amino acids: is -ve.
Explanation:
Entropy is defined as the measurement of degree of randomness in a system.
It is represented by symbol S and we can only measure a change in entropy which is given by .
If there is decrease in randomness , the sign for is -ve and If there is increase in randomness , the sign for
is +ve.
1. Water freezing: Entropy decreases as we move from liquid state to to solid state and thus is -ve.
2. Water evaporating : Entropy increases as we move from liquid state to gaseous state and thus is +ve.
3. Crystalline urea dissolving : The molecules convert from solid and ordered state to aqueous phase and random state. Thus the entropy increases and thus is +ve.
4. Assembly of the plasma membrane from individual lipids: random lipids are associating to form a single large polymer and thus entropy decreases and thus is -ve.
5. Assembly of a protein from individual amino acids: random amino acids are associating to form a single large polymer and thus entropy decreases and thus is -ve.

Here's what I get.
Explanation:
Your unbalanced nuclear equation is:
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
95 = x + 2, so x = 95 - 2 = 93
243 = y + 4, so y = 243 - 4 = 239
Element 93 is neptunium, so the nuclear equation becomes
