CH 320M/328M Dr. Samoylenko Homework # 4 11 Q 15 - Fill in the boxes with the product(s) for the following reactions. Draw only the predominant regioisomer and indicate the stereochemistry where appropriate. If a racemic mixture is formed, you may indicate this using a wavy line or mark the chiral center with an asterisk (*), and write racemic in the box. You may also draw both enantiomers and write RACEMIC in the box.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.
