SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass

In order to find the connection between the level of education and income‚ research methods need to established. To find the relationship between the two‚ I would use the methods of survey and experiments. Survey method allows a collection of a specific population and from that populations a sample population can be extracted to represent the whole. Given a random survey preformed at a local festival would give the general population a chance to participate since all sorts of people attend community

The essential part in this practical is to plan the experiment in detail in order to obtain substantial data. Firstly we have to identify our controlled variables which will be kept constant throughout the experiment. By carrying out this practical it is ideal that students

The first symbol I used that symbolizes me is a soccer ball. A soccer Ball symbolizes me because soccer is my passion. I first started playing soccer when i was four years old and have played ever since. I play club soccer at Charlotte Soccer Academy and i’ve been on the varsity team at Piedmont all 4 years of High School.

Evil & Power In After the Ball‚ The Sorcerer’s Apprentice‚ and On Evil‚ Guilt‚ and Power In these three pieces we have read there is a strong thread of evil and power separately throughout each of them and also how evil and power play a role when the other is present. Each piece views evil and power differently but also has common ideas. A common idea in each piece is that power can be good or evil depending on the factors involved. Nietzsche wrote that power is happiness and this is true in

I choose this experiment because i like doing stuff( projects‚ experiments.) in sports. I think this is a good experiment is a really fun and it falls good in the topic. I also chose this experiment because i think it’s really easy to do by yourself and i have all the materials to conduct it. i also chose this experiment because i’m kind of like an expert in this topic because i have been in football for like 3 years so i think i know alot about the balls grip and how it affects the length.
