Me! i think the answer to this is c because gas produced from liquid has the greatest release in entropy, right? and c is the only option producing gas. me out! is c the right answer or which one is?
the systems that shows the greatest increase in entropy is -
a.2h2 + o2®2h2o
b. nacl ®na+1 + cl-1
c.2h2o ®2h2 + o2
d. agcl3®ag+3 + 3cl-1

c. 2H₂O → 2H₂ + O₂

Explanation:

Entropy is the state of randomness or disorderliness of the particles of a system. The more random and disorderly a system is, the more its entropy. When the physical state of matter changes, there is a considerable change in the entropy of such a system.

The increasing order of entropy is as listed below:

               Solid < liquid < gas

Gases have the highest randomness in all states of matter.

From the equation of the reaction in option C, we see that water is going into the gaseous phase. The products of the reaction are hydrogen and oxygen gases. This is an increase in entropy.

Reaction B and D produced ions which are in aqeous solutions. They move from originally solid sate to a liquid phase.

Reaction A takes gases and turns them into water. This is a decrease in entropy.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

your answer is c) plasma
