1. Imagine that you and a friend went to sea for catching fish by boat. However, in the middle of the sea, the boat that you board had suffered a major engine problem. You are not able to ask for helps because your phone had running out of battery. a) Based on your knowledge as chemistry student, you are required to build a battery using existing materials surrounding you so that you may able to recharge your mobile phone. b) Explain the chemical processes involved in your innovation. c) Calculate the voltage you have generated from the battery you made.
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
