ABSTRACT The Batteries form a significant part of many electronic devices. Typical electrochemical batteries or cells convert chemical energy into electrical energy. Batteries based on the charging ability are classified into primary and secondary cells. Secondary cells are widely used because of their rechargeable nature. Presently‚ battery takes up a huge amount of space and contributes to a large part of the device’s weight. There is strong recent interest in ultrathin‚ flexible‚ safe energy storage

Title: Redox Reactions Research Question: Is it possible to determine if a redox reaction took place by using only the equation? Hypothesis: Yes‚ I believe it is possible to determine if this reaction took place by using the oxidation numbers in the equation. Variables: 1. I cleaned the reaction surface to limit contamination 2. I held the chemicals at approximately a 90 degree angle for consistency Introduction: Redox reactions occur when both oxidation and reduction take place. All atoms

Chemistry 1225 Lab Write-Up #13 Abstract Electrolysis is a method of using a direct electric current to drive an otherwise non-spontaneous chemical reaction. During electrolysis‚ hydrogen atoms (H2) are reduced at the cathode whereas the oxygen atoms (O2) are oxidized at the anode. There were three different solutions used in the experiment in order to have a better understanding of electrolysis reactions. From each solution‚ reaction equations were produced. The reactions could be observed from
