A man sits on the grass eating a doughnut and sipping iced tea. The sun is a glowing ball in the sky, making the air warm. He gets up and makes sure his chainsaw is filled with gasoline. The fumes make him cough. He starts the motor, lifts his chainsaw, and saws a branch off a tree. The branch falls to the ground, knocking over his iced tea. By this time, the ice in his tea has completely melted. The tea pours over some ants that were munching on doughnut crumbs. With renewed energy from the snack, the ants grab their crumbs, lift them onto their backs, and scurry away. a. List the four states, or phases of matter and give one example of each from the story above.

Lewis structure and molecular geometry for nh2cl

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
