Which of the following processes should lead to an decrease in entropy of the system? Select as many answers as are correct however points will be deducted for incorrect guesses. Select one or more: Decreasing the temperature Condensation of water (dew) onto grass Increasing the volume of a gas from 11 to 2L Increasing the temperature Decreasing the volume of a gas from 2 L to 1 L Melting of ice into liquid water

Which of the following processes will have a positive value of ΔS for the system? In other words, for which processes will the entropy will increase? If you aren't sure, find the equation you need and plug in some sample numbers. Mixing of two gases Compression of a gas Expansion of a gas Freezing Heating Boiling Condensing Cooling Melting

AgCl (s) + --> <-- Ag + (aq) + Cl- (aq) Shown above is information about the dissolution of AgCl in water at 298 K. In a chemistry lab a student wants to determine the value of s, the molar solubility of AgCl, by measuring [Ag+] in a saturated solution prepared by mixing excess AgCl and distilled water. How would the results of the experiment be altered if the student mixed excess AgCl with tap water (in which [Cl-] =...

Entropy (S) The second factor involved in determining whether or not a process is spontaneous is the change in randomness or entropy (AS). Entropy is represented by the symbol S. Again, experience can help us understand the relationship between entropy and spontaneous processes. If we look at the two drawings below, we can predict which picture represents the stack of marbles "before" and after they are bumped. We expect the stack of marbles (less random, lower entropy) to be the...

Indicate whether the entropy of the system increases or decreases for each of the following processes. Include a BRIEF explanation. Make up a process for (d) and indicate if the entropy of the system increases or decreases in that process, and provide a brief explanation as well. a) Water boiling at 100.0°C b) 2H2(g) + O2(g) ---> 2H2O(g) c) liquid water freezes at 0.0°C d) e) water vapor expanding from 1.0L of volume to 2.0L of volume f) mixing 10mL...

I need help figuring out the flowchart and if I have the right
answers for the prelab please and thank you!
Group I, the Chloride Group BACKGROUND The precipitating reagent for the chloride group is chloride ion in an acidic solution. Only three of the 18 metal ions form a precipitate with this reagent: silver ion (Ag'), mercury(I)ion (Hg). and lead ion (Pb). Since lead chloride is somewhat soluble, it is not completely precipitated here, and a low concentration of...

For the prelab questions I have some answers but I don’t know
if they’re right. If they’re wrong, I would greatly appreciate an
explanation for the correct answer. I’m really trying to learn the
material but it’s hard now that classes are cancelled so I’m sorry
if these are dumb
