COMPOSITION AND SEPERATION LAB REPORT INTRODUCTION The purpose of this experiment is to study the physical and chemical properties of popcorn, sand, salt and iron fillings in order to separate them out and to find the percent composition of them. The percent composition of a component in a compound is the percent of the mass of the component in relation to the total mass of the compound. By using the percent composition, one can find the amount of water that is in a kernel of popcorn or find the total percent recovered when separating out different components of a solid mixture. EXPERIMENTAL Please refer to the Chemistry 184 Laboratory—Fall 2011 website: Lab #2 Composition and Separation Lab *Note that instead of using a Bunsen Burner, a ceramic hot plate was used. *Note that only one kernel of popcorn was used instead of several.
I hate it when there is not a lot of popcorn in the microwavable bags. Sometimes there are more kernels, so I did this project to see which brand was the best to eat.

Fourthly, we let the egg sit for twenty four hours. Then we transferred the egg from corn syrup into distilled water. Then we let egg sit for twenty four more hours. After that you can do whatever you would like to with the egg because the experiment is complete. Results (Data): Day 1: Bubbles started to form around the egg The egg started to float to the top of the container The vinegar started to soak into the egg (Displace) Day 2: There was NO bubbles.
He developed respiratory problems in 2007, after regularly eating popcorn. "Popcorn lung" is a form of irreversible obstructive lung disease that scars the lung and makes it difficult for air to flow out. The verdict is the latest in a series of successful cases, including by popcorn plant Wayn Watson (left) says he had not had any workers who became ill. The cases link microwave popcorn since being diagnosed. diacetyl, an ingredient in the flavouring, to health problems.
Experiment Date: 11/22/2014 Date Submitted: 11/25/2014 TITLE: Caloric Content of Food PURPOSE: To measure the energy content of various food items, as well as become familiar with energy units like calories and joules. PROCEDURE: First, weigh your empty beaker, fork, beaker with half water, mass of marshmallow walnut popcorn, and the test tube holder. Then record the temp of the water in the breaker. The next thing you do is light the marshmallow on the fork and hold under the beaker making sure to stir the water occasionally. Once the marshmallow is completely burnt, record the temp of the water and weigh the fork with the marshmallow.
Hold each piece of bread to be dropped with both hands making sure to release with both hands at the same time for each drop. RESULTS: Amount of Jelly 1st Drop 2nd Drop 3rd Drop No Jelly Jelly Up Jelly Up Jelly Up ½ Jelly Covered Jelly Down Jelly Down Jelly Up Totally Covered Jelly Up Jelly Up Jelly Up CONCLUSION: This experiment was conducted to show whether different amounts of jelly would have an impact on which side the bread landed. If the jelly is spread evenly across the entire surface or spread on only half of the surface it
In my project I will be talking about how corn syrup does not need to be added to every sweet good. I believe corn syrup is a sweetener just like sugar. For example, lollipops consist of both sugar and corn syrup, but why? I am going to find that out during my experiment. There are different types of substances in lollipops but it all comes down to both sugar and corn syrup.
During this test I used 2mL of Egg Albumen solution, 2mL of honey solution, 2mL of the protein solution, 5 drops of the unknown solution (3), and 3 drops of Biuret reagent to each solution. My third and final test was for Lipids
* Time it right: Babies are usually ready to try solid food between 4 and 6 months, but check with your baby’s doctor beforehand. * Watch for signs: Good head control, a growing appetite, and interest in what you're eating are all indications that your baby is ready to try solids. Start simple: For most infants, you can start with any pureed solid food include pureed sweet potatoes, squash, applesauce, bananas, peaches, and pears. First, nurse or bottle-feed your baby. Then give him one or two teaspoons of pureed solid food.
Materials: 1) Beakers 2) Water 3) Plastic wrap 4) Rubber band 5) Light corn syrup 6) Vinegar 7) 2 raw egg (large) 8) 2 graduated cylinder (100ml, 50ml) 9) Marker for labeling cup 10) Tri Beam scale Procedure: 1) Measure 130ml of vinegar into the beaker. 2) Gently place the egg into the vinegar. Make sure the egg is completely covered by the vinegar. 3) Weigh all of the items o the scale 4) Cover the beaker with plastic and secure it with a rubber band. 5) Label the beaker with your name and period.
