The visible radiation from a glow stick will snuff out more rapidly at higher temperatures because temperature affects the rate of the chemical reaction. Question: Will a glow stick snuff out more rapidly while in a higher temperature? Purpose: To find if a freshness stick will decease out quicker in a cold temperature or a…

Introduction             Electroplating can be defined as the deposition of a metallic coating through the subjection of an object with a negative charge to a solution containing a salt containing positive metal ions. Under the influence of an electric charge, the positive ions are attracted to the negatively charged object where they are reduced hence…

Introduction The purpose of the experiment was to oxidize and identify an unknown alcohol using hypochlorite, or household bleach. During the experiment, the bleach oxidized the secondary unknown alcohol into a liquid ketone which was distilled or boiled to find the boiling point and then identified using a chart of unknown identities and boiling points….

1.0 INTRODUCTION This report is a practical experience acquired by me in the course of my industrial training at Druckfarben Nigeria Limited (DFN) under the student industrial work experience scheme (SWIES). In the earlier stage of science and technology education in Nigeria, students were from their respective institutions without any technical knowledge or working experience….

According to the kinetic molecular theory, gas particles are constantly in motion just like other forms of matter. However, their movement is distinct in that it is characterized by random translation. In solids, the particles primarily undergo vibrational motion. In liquids, they mainly vibrate and rotate, and also experience some translational motion. Gas particles move…

IntroductionIn this lab I observed the burning of a candle very closely. I found out that the candle needs oxygen to burn, that it produces carbon dioxide similar to the way that my body produces carbon dioxide, and that a candle produces water as a second waste product. I learned that if I hold an…
