For each chemical reaction listed in the first column of the table below, predict the sign (positive or negative) of the reaction entropy A.S. If it's not possible to decide with the information given, check the "not enough information" button in the last column. Note for advanced students: Assume the temperature remains constant. Assume all gases and solutions are ideal. reaction H₂O(1) + AL S₂ (s) → H₂S (g) + Al₂O₂ (s) 2C₂ H₂(g) +70₂(g) → 4CO₂(g) + 6H₂O(g) BaCl₂ (aq) + K₂SO₂(aq) → BaSO₂ (s) + 2K Cl(aq) sign of reaction entropy O AS rxn AS rxn not enough information. AS < 0 rxn AS rxn > 0 AS not enough information. AS <0 rxn rxn >0 >0 not enough information.

For each of the following reactions determine if the change in entropy was positive or negative:A) Water at 40°C → Water at 25°CB) 2NO2(g) → N2O4(g)C) CH3OH (l) → CH3OH (g)D) PbCl2(s) → PbCl2(aq)

1:44 1 LTE 4 1 Search Question 20.b of 23 Show Answer Consider the reaction Cl2(g) + Br2(g) → 2 BrCI(g) at 25 °C. Which of the following best explains why the change in entropy is so small? A) All of the components in the chemical equation are gases. B) There are the same moles of gas on both sides of the reaction. C) The temperature of the reaction does not change.

For the following reactions, indicate whether the entropy of the system increases, decreases, or remains nearly the same. a. Al3+(aq) + 3 OH-(aq) → Al(OH)3(s)b. CaCO3(s) → CaO(s) + CO2(g)c. Mg(s) + Cu2+(aq) → Mg2+(aq) + Cu(s)

8 As you dissolve salt in water, what change would you expect to occur? A B C D The entropy of the system will increase. The kinetic energy of the water molecules decreases. The salt consumes energy as it transfers entropy The water molecules become more closely packed as the temperature increases

Number 7 please

What is the change in entropy, AS, for the following reaction? Use Table G in your book for values of standard entropies. Your answer should be in J/K mol. CaCO3(s) + 2 H'(aq) → → Ca² (aq) + H₂O(l) + CO2(g) O 264.9 J/K mol O 118.6 J/K mol 394.3 J/K mol 137.7 J/K mol 2

Compare what will happen to the entropy of the whole system in the following two scenarios: A) if the oil molecules are all clumped together and the clump is surrounded by water and B) if the oil molecules are spread out evenly throughout the water, each individual oil molecule surrounded by water?
