A standard galvanic cell consists of Cr3-| Cr2 and CD2-| Cd half-cell compartments connected by a salt bridge. Which of the following statements is correct? Note: See a chart showing the default reduction potential. (Choose all those that apply.) In the external circuit, the electrons flow from the | CD2- Compartment D at the Cr3-| Cr2 Bay. The cathode compartment is the CD2-| Cd compartment. Cd is oxidized to the anode. The cathode compartment is the Cr3-| Cr2 Bay. When the cell is executed, the anions are executed by… In the case of service contracts in the United States, the use of SOWs remains strong, although objective statements (SOOs) and performance statements (PWS) have become increasingly popular because of their focus on performance-based concepts, such as desired service results and performance standards. SOWs are usually used when the task is known and can be described in some terms. They may be preferred if the government does not want innovative approaches or if differences in contractors are considered a risk. SOOs define high-level performance results and objectives, and PWS highlight desired results, results and objectives at a more detailed and measurable level, while SOW provides explicit instructions on the direction of work for the contractor or supplier.
SOWs are generally subject to “contracting” declarations on mandatory compliance (z.B. “This task is carried out in accordance with the Agency`s Xyz Directive, date mm/dd/yyyy). In practice, SOWs can also include references to desired performance results, performance standards and metrics, thus bridging the distinction between SOOs and PWS. Apart from good practice, there are few government guidelines that clearly state how and when SOWs are used in relation to SOOs or PWS. While the FAR PWS defines the definitions in Part 2 and refers to SOOs and PWS in Part 37.6 Performance Based Acquisition, SOWs are not addressed. SOWs are usually included in the government`s request (RFP or RfQ) and are transferred into the final contract, as negotiated with the bidder. In federal applications and contracts, SOWs are included in Section C “Descriptions/specifications” of the uniform contract format, but can also be inserted as an appendix to Section J.
