A) determine ΔrH° for the complete combustion of liquid acetone at 298.15 K. Assume that water is produced in the gas phase. b) What is the work associated with this combustion at 298.15 K? Express your answer in

(i) joules/mol; and

(ii) calories/mol. (Per mole of balanced reaction from part a.)
(2.75 points)

(c) If 49.6 g of liquid acetone was combusted, and all of the resulting heat was used to convert liquid water at 42.9 °C to gaseous water (steam) at 100.0 °C, how many grams of water could undergo this change?

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
