Benzene gas (C6H6) enters a well-insulated reactor operating at steady state at 77oF, 1 atm, and burns completely with dry air entering as a separated stream at 300oF, 1 atm. The combustion products exit the reactor at 1600oF. Kinetic and potential energy effects are negligible. Determine the percent of theoretical dry air provided.

You have a pick-up truck that weighed 4,000 pounds when it was new. you are modifying it to increase its ground clearance. when you are finished

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
