electrolytic conductor is accompanied by chemical changes at the electrodes. (Examples of such reactions can be found on pages 743 -747 of your text.) Electrolytic conduction plays an important role in the function of electrochemical cells‚ batteries‚ electrolysis‚ and electroplating. We know that solutions can be nonelectrolytes (nonconductors)‚ weak electrolytes (poor conductors)‚ or strong electrolytes (good conductors). In this experiment we will determine the conductivity of such solutions in a

Fossil Fuels which include Petroleum and Natural Gas were formed million years ago from the remains of plants and animals‚ are responsible 40% and 20% respectively for the world ’s energy. They were first discovered about 700-900 years ago‚ however since the first modern petroleum industry began in 1859‚ the demand for fossil fuels has escalated beyond our control. It had taken 50-300 million years to form‚ and yet we have managed to burn roughly half of all global oil reserves in merely 125 years

SYNCMTR1 Synchronous Motor Characteristics Copyright 2004 Kilowatt Classroom‚ LLC. Synchronous Motors are three-phase AC motors which run at synchronous speed‚ without slip. (In an induction motor the rotor must have some “slip”. The rotor speed must be less than‚ or lag behind‚ that of the rotating stator flux in order for current to be induced into the rotor. If an induction motor rotor were to achieve synchronous speed‚ no lines of force would cut through the rotor‚ so no current would

A miser is ever in want. --Greek proverb Preparing to experiment You will be provided with the following materials: Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are

ABSTRACT Obesity is one of the biggest problems in America. Though we live in a country with advanced technology‚ and great economic power; we also live in a country plagued with obesity. In the past twenty years‚ obesity has become so familiar with people of all ages including young children. Obesity is no longer a concern of appearance; it is more a concern of health. Obesity can also leads to other health problems such as diabetes‚ heart disease‚ arthritis‚ and hypertension. What is the
