A change in the entropy of a system indicate that the disorder of the system has changed. Option A
<h3>What is a change in entropy?</h3>
A change in entropy indicates is a measure of the disorder, or randomness, in a system.
An increased value of entropy means more disorder, and a decreased value of entropy means less disorder.
These changes in entropy occur spontaneously
Thus, a change in the entropy of a system indicate that the disorder of the system has changed. Option A

One positive charge wherever the atom loses an electron!
<span>the distance between peaks of a wave</span>
<span>mainly the interaction of analyse and the base comes in mind and that way how solvable it is. if you but ethanol in water there is a change that it's blocking the space between the base and water and so on also let's other substances be carried away. so basically it would give lower distance for more polar and vice versa. also what kind of base are you using if it's selective for some substances </span>
Weight of Fe=2*55.8=111.6
[Because in the balanced reaction there are two moles of Fe]
Weight of FeCl3=(2*((55.8)+(3*35.5)))= 253.6
[weight of Cl is 35.5]
2Fe + 3Cl2-----> 2FeCl3
111.6g 253.6g
15.3 g ?
Cross multiply
Weight of FeCl3=(253.6*15.3)/111.6=34.7g
if i did this right i believe the answer is 34.7g.
