Aluminum Foil Lab

1. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). Using your results from Data Table 1 as a guide, how would you test this material for the presence of sodium bicarbonate?

When we placed the aluminum foil in copper chloride, a chemical reaction occurred. Before the reaction took place we had aluminum foil and copper chloride as our reactants. After the reaction happened, the products were aluminum chloride and copper. After the foil was placed in the copper chloride, the color of the aluminum foil had changed from a shiny silver, to a deep red. Also, the color of the copper chloride changed from a light blue to a murky green. At the start, there was aluminum and copper chloride. During the reaction, the aluminum and copper chloride atoms rearranged to form aluminum chloride and copper as two separate substances, also being different substances than the ones that we started out with. A chemical reaction is when

The purpose of this experiment is to perform a two step reductive amination using o-vanillin with p-toluidine to synthesize an imine derivative. In this experiment, 0.386 g of o-vanillin and 0.276 g of p-toluidine were mixed into an Erlenmeyer flask. The o-vanillin turned from a green powder to orange layer as it mixed with p-toludine, which was originally a white solid. Ethanol was added as a solvent for this reaction. Sodium borohydride was added in slow portion as the reducing agent, dissolving the precipitate into a yellowish lime solution. Glacial acetic acid and acetic anhydride were added to the mixture while refluxing, which converted the lime colored solution into a clear mixture. The flask was cooled in an ice bath and the solution

The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper.

The items that were massed were the evaporating dish, watch glass, and NaCO3. The materials were massed once before and once after being heated in the drying oven. The mass of the evaporating Dish before was 46.57 g; while after being heating was 60.15 g. The mass of the watch glass before was 57.97 g and after was 48.75g. There were two masses taken for the substance NaHCO3- one with the evaporating dish and one without, subtracted out after the lab was concluded. The mass of the substance with the dish was 48.79 g before and 62.33 g after; meanwhile, the mass of the substance without the dish was 2.22 g before and 2.18 g after. The mass of the NaHCO3 had changed after the reaction occurred along with after it was placed on the hot plate and being in the drying oven. When the reactants were in the evaporating dish with the hotplate on, the acetic acid and sodium had been chemically bonded in a combustion compound. The mass went from two different reactants to one product and two evaporated

Two kinds, a short story by Amy Tan, explores the relationship between an immigrant mother and her first generation daughter. The mother, who has faith in the American dream, values the belief that to be happy, you have to be famous and change yourself; Ni Kan, the daughter, yearns for a personality of her own. Tan characterize these women as foils to each other. As a result of them being foils, they’re relationship is strained and they never have a close bond until Ni Kan grows older. Tan uses these characters to show that with each generation the American dream is changed. Amy Tan demonstrates that different generations of people have different views on the American dream through Ni Kan ‘s mother dream of fame and fortune for her child, and Ni Kan’s dream of finding an identity. Tan believes the cause of the barrier between mother and daughter is due to their foiled dreams.

In cycle one, the double displacement reaction, Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) occurred, the result of the reaction was that the reaction mixture began to bubble with the copper filling dissolving and a vapor like substance leaving the reaction. Furthermore, when water was added, the color change, from brown to a blue color pigment. Then in Cycle two, another double displacement reaction occurred, Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq), which resulted in the reaction becoming cloudy and a darker shade of blue. Following cycle two, a decomposition reaction occurred as the result of heat being administered to the mixture, thus the following reaction occurred in cycle three, Cu(OH)2(s) → CuO(s) + H2O(l). As a

A foil is most commonly defined as a character who contrasts with another character. Foils are all around you, yet they usually go unnoticed. The Wicked Witch and Glinda the Good Witch. Peter Pan and Captain Hook. Shrek and Donkey. Sharkboy and Lavagirl. Mike and Sully. Katniss and Peeta. Anna and Elsa. In almost every Movie or TV Show, foils are present. Foils create the small balance needed in literature and in real life.

A red-orange color developed while the test tube was in the boiling water. After the mixture had cooled, the color was red.

I was following my father, trying to keep up. With each step, my foot sank into snow up to my knee. The snow was not really that deep, but I was eight years old. We were emptying zinc buckets filled with clear, odorless, tasteless liquid to be used in a process I would come to know as sugaring. The liquid was sap from maple trees that would eventually be boiled down to become syrup. It was that time of year again.

The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis. Being, if hot and cold water were combined, then the cold water would move beneath the hot water because cold water is denser than hot water.

In the first experiment, half a gram of magnesium was combined with 3 milliliters of hydrochloric acid in a glass beaker. The magnesium looked like a gray powder. The hydrochloric acid appeared to be clear liquid and looked very similar to rubbing alcohol. Before, the reaction took place the magnesium and hydrochloric acid weighed 4.44 grams when weighed together. Once the magnesium and the hydrochloric acid were mixed together, the bottom of the beaker felt warm and it started to foam. It produced a strong odor, and became a thick white color. The magnesium also appeared to be lighter after the reaction, After we weighed the beaker the sample still weighed 4.44 grams. The change in color, production of gas, smell, and increase

Purpose: To recognize the evidence of a chemical change and to prove the law of conservation of mass by observing a series of chemical reactions involving copper. A specific quantity of copper will be transformed through a series of chemical reactions to form new substances and then recovered as solid copper. A percent yield will be calculated to determine the amount of copper recovered from the chemical reactions.

Everyone knows the simple and easy experiment of vinegar and baking soda, but do you really know how it works. This paper will not only explain what makes these two very different chemicals react, but also what materials you will need to accomplish this easy science experiment. Baking soda and vinegar are two different chemical with two very different uses, they are not really even supposed to be used for a science experiment, take vinegar for example, some individuals use vinegar for cooking. Baking soda has a very different use, it is used for bee-stings.

　　Aldehydes and ketones are two similar functional groups containing the carbonyl group. In this experiment, the main objectives are to be able to do qualitative tests on the samples, to be able to write the respective correct chemical reactions for each sample on each test, and to be able to differentiate aldehydes and ketones from one another and from other compounds. The tests were performed by mixing the respective reagents or compounds to each of the samples and then the mixture was observed for a reaction. The oxidation test, and 2,4-DNPJ test confirms that formaldehyde and benzaldehyde
