Consider the following endothermic reaction.  A(s) ⟶⟶A(g) Assuming the reaction takes place at constant temperature and pressure, which of the following is correct? answer choices: a) q is negative and w is positive.   b) q is positive and w is negative. c) q and w are both negative.  d) q and w are both positive.

Under what conditions will the quantity q be a positive number and the quantity w be a positive number? Oq is positive when the system loses heat to surroundings, w is positive when the surroundings does work on the 4 system. qis positive when the system loses heat to surroundings, w is positive when the system does work on the surroundings. qis positive when the system gains heat from surroundings, w is positive when the surroundings does work on the system. O qis positive when the system gains heat from surroundings, w is positive when the system does work on the surroundings.

4. The reaction of 250.0 mL of a 1.00 M hydrochloric acid solution with 250.0 mL of a 1.00 M sodium hydroxide solution was carried out in a constant pressure calorimeter. The total heat capacity of the calorimeter plus solutions was 6.45 kJ/K. The temperature of the calorimeter and solutions increased by 2.11°C. What is AH (in kJ) for the neutralization of 1.00 mol HCl(aq) by NaOH(aq)? A) -54.4 B) -21.2 +12.6 +54.4 E) -12.6

Resubmitting this question because I got denied the first time. I'm not giving you the values of standard S from appendix C because it's NOT RIGHT. My teacher flat out told me that the values from the book are wrong so please don't deny this question again because I didn't supply the book values.  Can someone please solve this question I keep getting it wrong I got -73.3J/K*mol but it says its wrong. Can someone help me get the right answer.  Thank you
