COMPOSITION OF PENNIES USING REDOX AND DOUBLE DISPLACEMENT (PRECIPITATION) REACTIONS Pre- Lab 8 Objective: The purpose of this experiment is to determine the percent composition of pennies using oxidation-reduction and double displacement reactions as well as titration techniques. We will take a post 1982 penny and place in a strong acid dissolving the zinc core and leaving behind the copper coating. We will figure out the percent composition from the mass of copper and zinc using titration and precipitation

Networking Topologies and TCP/IP protocol Bus Topology It just doesn’t get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus‚ backbone‚ or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions

tactile‚ and semantic. Acoustic encoding processes sounds and words for storage and retrieval. It is also believed that short-term memory relies on this form of encoding. Visual encoding processes images and other visual sensory information‚ as well as using input from other systems in the body. Tactile encoding is how feelings are processed‚ usually through the sense of touch. Lastly‚ semantic encoding is processing sensory information that has a specific meaning. Long-term encoding is dependent on semantic
