Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

CHEM XXI Project Report Worksheet (4 pages max.) Experiment title: How Do We Identify an Unknown Substance? Guiding questions: State the question or questions that that you were trying to answer in this lab. How do you determine the two unknown types of plastic? What are the two unknown plastics? Safety considerations: Briefly describe the safety measures you had to take to perform the experiments. Before entering the lab‚ I put on my lab coat and practiced using

Introduction The major component of eggshells is calcium carbonate (CaCO3). Calcium carbonate cannot be dissolved in water‚ but can dissolve in an acid using the reaction: 2HCl(aq)+CaCO3(s) Ca2+(aq)+CO2(g)+H2O+2HCl-(aq) This reaction is not used to titrate the CaCO3 because it is very slow when the reaction is close to the endpoint. Instead adding an excess of acid to dissolve all of the CaCO3 and then titrating the remaining H3O+ with NaOH solution can achieve the determination of the amount

My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they

The film “Salt of the Earth” by Michael Wilson is a 1954 film that shows the prejudice ways against long time resident Mexican-American workers. It takes place in a small town in New Mexico. After a mining accident‚ workers began protesting the unfair wages and serious hazardous working conditions. A man by the name of Ramon helps the workers organizing the protest but is also found treating his wife Esperanza unfairly as well and that was a concern because why try and protest about someone being

President Abraham Lincoln began to develop his plan for reconstruction. Lincoln wanted to reassemble the North and South after the war ended. Lincolns game plan for Reconstruction included the Ten-Percent Plan. The Ten-Percent Plan stated that a state in the south could be reaccepted into the Union once ten percent of its voters testified an oath of allegiance to the Union. Delegates were then elected by voters to establish new state governments and draft revised state constitutions. On May 29‚ 1865‚ Johnson

Unit 7 Final Project Part 1 One concept that I have chosen is percentages. A percent is a fraction that has a denominator of 100. Finding the percent of a number‚ and finding the missing percent could be very useful in the profession that I have chosen. The profession that I would like to pursue is accounting. Using percentages is used in many ways in accounting. One way is to do a trend analysis. A trend analysis calculates the percentage change for one account over a period of time of two

Drinking too much water can lead to hyponatremia‚ water intoxication‚ water poisoning and death Liquid H2O is the sine qua non of life. Making up about 66 percent of the human body‚ water runs through the blood‚ inhabits the cells‚ and lurks in the spaces between. At every moment water escapes the body through sweat‚ urination‚ defecation or exhaled breath‚ among other routes. Replacing these lost stores is essential but rehydration can be overdone. There is such a thing as a fatal water overdose.

1. Prepare the salt‚ sugar‚ sand‚ and measuring teaspoon. 2. Once the ice cubes are set up in their bowls‚ quickly add the substances to the ice cubes so that they don’t melt before adding the substances. 3. Place three ice cubes quickly into each of the four bowls. 4. Arrange the ice cubes so that only the corners are touching‚ forming a triangular shape. 5. Carefully sprinkle ½ teaspoon (tsp.) of salt over the ice cubes in one bowl. 6. Sprinkle ½ tsp. of sugar over the ice cubes in another bowl
