Now build a model of salt. Use the blue, squarer marshmallows to represent the chlorine atoms and the pink, rounder marshmallows to represent the sodium atoms. Connect the marshmallows with toothpicks using the picture in part A as a guide. Drag each image to the correct location on the model. Each image can be used more than once.

Oxygen gas enters well-insulated diffuser at 25 lbf/in.2, 420r, with a velocity of 860 ft/s through a flow area of 1.6 in.^2. at the exit, the flow area is 12 times the inlet area, and the velocity is 19 ft/s. the potential energy change from inlet to exit is negligible. assuming ideal gas behavior for the oxygen and steady-state operation of the diffuser, determine the following: (a) the exit temperature, in r(b) the exit pressure, in lbf/in.^2 (c) the mass flow rate, in lb/s
