Rather than combusting hydrogen in the presence of oxygen, the overall reaction (1/2) O2 H2 H2O is actually carried out as two `half-reactions occurring at separate electrodes. To complete the reaction, this forces electrons to pass through an external circuit from one electrode to the other, and this current can be used to do work; e.g., by driving a motor. Typical operating conditions for a solid-oxide fuel cell are 500-900 C and 5-15 bar. Consider a fuel cell in which a pure oxygen stream and a pure hydrogen stream enter at 11 bar and 700 C with stoichiometric flowrates. Assume that these reactants are consumed completely, and that the water generated by the reaction leaves in a third stream at the same T and P. Assume that the fuel cell operates at steady-state with a uniform temperature of 700 C. a) Write simplified first and Give two examples of pioneer species. 3.What is Shirley Chisholm's overall purpose in her speech?A. to discredit the other candidates running for the Democratic nominationB. to persuade people that she is the right choice for the Democratic nominationC. to convince people that she has overwhelming support for the DemocraticnominationD. to pressure people to vote for her for the Democratic nomination A shipment of sugar fills 8 containers.

One end of the spring is attached to a wall, and the other end is connected to a movable object. The spring and object are compressed by 0.065 m, released from rest, and subsequently oscillate back and forth with an angular frequency of 11.3 rad/s. What is the speed of the object at the instant when the spring is stretched by 0.048 m relative to its unstrained length What are the duties of the attorney general?
