Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions AH is A This reaction is spontaneous only below -8. °C. (pick one) AS is (pick one) ✓ B This reaction is spontaneous except below 41. °C but proceeds at a slower rate below 172. °C. AH is (pick one) AS is (pick one) AH is (pick one) C The reverse of this reaction is always spontaneous. AS is (pick one) (pick one) positive negative unknown

Consider a barrel containing one copy of each of the 26 letters of the alphabet (A, B, C, …).A. What is the probability of drawing the first three letters of the alphabet (A, B and C) out inexactly alphabetical-order if you replace each letter back in the barrel after you look at it?B. What is the probability of drawing all 26 letters of the alphabet out in exactly alphabeticalorder if you replace each letter back in the barrel after you look at it?C. What is the probability of drawing the first three letters of the alphabet (A, B and C) out inexactly alphabetical-order if you keep the letter out of the barrel after you look at it?

A student used a pH meter to collect data for the titration of an unknown concentration of propanoic acid with a 0.150 mol/L solution of sodium hydroxide. The data table from the investigation is shown in the table below. Data for the Titration of Propanoic Acid with Sodium Hydroxide Volume of propanoic acid: 25.00 mL [NaOH] = 0.150 mol/L Volume of NaOH (aq) added (mL) 0.00 2.00 4.11 7.98 11.95 14.08 16.05 17.00 17.21 17.39 17.62 17.99 18.18 18.39 18.80 20.00 22.03 PH 2.83 3.84 4.20 4.64 5.03 5.27 5.61 5.90 6.00 6.09 6.23 6.74 8.80 10.92 12.24 12.56 12.69 Adobe 4343625416 00..
