What is the main idea in this diary entry? april 27 wow! we’re getting a new labrador puppy—temporarily. the puppy will be a part of our family, and we’ll spend a lot of time training him. but we won't be able to keep him, no matter how much we want to. that's because we're training him for the hearing ear association. a hearing ear dog assists a deaf person in much the same way that a seeing eye dog a blind person. it alerts its owner to important sounds, like a knock at the door, a morning alarm clock, or a whistling tea kettle. before the program places a dog with a deaf owner, the dog spends a year with a host family. that's us! our first job is to get the puppy accustomed to family life and to teach it basic commands. we’ll teach it to sit and to fetch. later, we’ll train the puppy in special hearing skills. a representative of the hearing ear association will deliver the puppy today. it's going to be an educational year for everyone!

Lem 2 the data below are for the system ethyl propyl ether (1)-chloroform (2) at 0.5 bar. use the data to answer the following questions (all questions refer to p d 0: 5 bar). a) what are the boiling points of the pure components at 0.5 bar? b) a mixture with the overall composition z1 d 0: 1 is brought to 47.6ä±c, 0.5 bar. what is the phase? c) 100 mole of a mixture with z1 d 0: 1 (state a) is mixed with 22 mole of pure ethyl propyl ether vapor (state b). the mixing takes place at 47.6 ä±c, 0.5. bar. what is the phase of the resulting mixture (state c)? if the state is a v/l mixture report the number of moles and mole fractions in each phase. d) plot the txy graph and show states a, b and c. the graph must be done by computer and should be properly annotated. ethyl propyl ether (1) - chloroform (2) at 0.5 bar t ( ä±c) x1 y1 t ( ä±c) x1 y1 42.9 0.000 0.000 49.0 0.470 0.455 43.0 0.020 0.010 49.1 0.520 0.520 43.9 0.065 0.029 48.9 0.567 0.592 45.4 0.156 0.089 48.3 0.652 0.720 46.4 0.215 0.142 47.6 0.745 0.815 47.6 0.296 0.223 46.7 0.822 0.872 48.3 0.362 0.302 45.7 0.907 0.937 48.7 0.410 0.375 44.6 1.000
