Now build a model of salt. Place your materials on a sheet of paper. The regular-size marshmallows can represent the larger chlorine atoms, and the mini marshmallows can represent the smaller sodium atoms. Connect the marshmallows
with toothpicks using the picture as a guide. What was difficult about building the model?

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
