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

Daily life in ancient Egypt revolved around the Nile and the fertile land along its banks. The yearly flooding of the Nile enriched the soil and brought good harvests and wealth to the land. These days we use most of their daily life. Three most important things in Egyptian daily life were papyrus and writing‚ food and cookery‚ and cylinder seals. One of the important things in Egyptian daily life was papyrus and writing. Paper is made from the papyrus plant by separating it with a needlepoint

Daily Life There are a variety of common courtesies that Americans should observe when in Mexico. Some of the important issues of cultural etiquette are described herein. When in Mexico Americans should refrain from calling themselves "Americans." Mexicans consider themselves Americans too since the whole continent is called America. Another part of Mexican culture that may be shocking to American’s traveling there is the way machismo is verbalized by male members of Mexican society. Making sexual

ferry. Finally‚ leave for school. My school starts at 9:00 am. I am usually in time for my class. My class teacher ever eulogizes me not for late school. The teachers come into our classroom and teach their respective subjects. I sit in front of the row and so‚ I can see the blackboard clearly. All of our teachers are good at teaching. We can ask them whatever we do not understand. We have a thirty minutes break time. Most students go to the canteen but I have my lunch only in the

the muscular requirements of work‚ automation greatly decreases the need for human sensory and mental requirements while increasing load capacity‚ speed‚ and repeatability. Automation plays an increasingly important role in the world economy and in daily experience. Automation has had a notable impact in a wide range of industries beyond manufacturing (where it began). Once-ubiquitous telephone operators have been replaced largely by automated telephone switchboards and answering machines. Medical

INTRODUCTION: ELECTROLYSIS Process used: The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes. For example‚ in the electrolysis of brine to produce hydrogen and chlorine‚ the products are gaseous. These gaseous products bubble from the electrolyte and are collected 2 NaCl +

Geometry (Ancient Greek: γεωμετρία; geo- "earth"‚ -metron "measurement") is a branch of mathematics concerned with questions of shape‚ size‚ relative position of figures‚ and the properties of space. A mathematician who works in the field of geometry is called a geometer. Geometry arose independently in a number of early cultures as a body of practical knowledge concerning lengths‚ areas‚ and volumes‚ with elements of a formal mathematical science emerging in the West as early as Thales (6th Century
