Two and half moles of an ideal gas with cv, m=1.5r undergoes a carnot process defined by following four states: a (1.50 atm, 400 k), b (1.00 atm, 400k), c (? atm, 300 k) and d (? atm, 300 k). a) calculate q, w, au, ah and as for paths a-b, b-c, c-d and d-a. b) what is the efficiency of this carnot cycle engine with ideal gas as the working substance?

B

Explanation:

B (1.00 atm, 400K)

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
