Cations and Anions Reaction Introduction: This experiment seeks to explore different chemical reactions conducted in the lab. A cation is defined as positively charged ions‚ which are K+ and Pb2+ in this experiment‚ and an anion is termed as negatively charged ions‚ which are CrO4 2- and NO3 2-. The major objective of this lab experiment was to examine the reaction between cations and anions‚ as well as observing‚ and documenting the chemical reactions. We will be demonstrating the reaction between

Autonomous Management of Everyday Places for a Personalized Location Provider Abstract—Currently available location technologies such as the global positioning system (GPS) or Wi-Fi fingerprinting are limited‚ respectively‚ to outdoor applications or require offline signal learning. In this paper‚ we present a smartphone-based autonomous construction and management of a personalized location provider in indoor and outdoor environments. Our system makes use of electronic compass and accelerometer
