Identification of type of Chemical Reactions Skylar Scanlan Wednesday, January 25 Partner: Sarah Catirino Ms. Ciraco SNC2D Introduction Chemical reactions are a fundamental part of Chemistry and Science. This allows for determining what chemical reactions are safe and which are dangerous. This is significant because this can reveal important reactions and helps to understand various properties of substances. During this experiment, various chemicals will be mixed and their reactions will be identified along with the changes. The observations of the reactions will be displayed on a chart with three columns labelled; before reaction, after reaction, and proof of chemical reaction for the four reactions. During this experiment, …show more content…

The results of this chemical reaction produced gas and became cloudy and grainy. During Part 2 of this lab, Zinc reacts with Hydrochloric Acid to produce Zinc Chloride and Hydrogen gas. The skeletal equation for this reaction is Zn + HCL → ZnCl2 + H2 and the final balanced equation is Zn + 2HCL → ZnCl2 + H2. Observing this reaction shows that when Zinc reacts with Hydrochloric Acid the Zinc will begin bubbling upwards and form a fas. The Zinc produced a white smoke and the liquid became cloudy. During this reaction, the Zinc was also disintegrating. During Part 3 of this reaction Copper Sulfate and Zinc reacted with eachother to produce Zinc Sulphate. The word equation for this reaction is Copper Sulfate(aq) and Zinc (s) react to produce Zinc Sulphate (aq) and Copper (s). The Skeletal equation is CuSO4 + Zn → ZnSO4 → + Cu and the final balanced equation is CuSO4 + Zn → ZnSO4 → + Cu. During this reaction, the observations showed that after four minutes of the reactants being mixed together the liquid looked grainy. After 7 minutes a clear dark blue ring formed around the top of the liquid. The proof of a chemical reaction for the reactants is that the liquid began to precipitate.

While the solution dissolved, 50 mL of distilled water was added to a 150 mL beaker and heated on the hot plate. When the solution started to boil 2.65 grams of Na2SiO3*5H2O was added to the beaker with a stir bar and heated to a gentle boil. When both solutions began to boil, the sodium silicate solution was slowly added to the sodium aluminate. The solution was kept at 900C for 60 minutes and stirred with stir bar. After 60 minutes, the zeolite solution was cooled for 5 minutes and for the magnetized zeolite , 0.78 grams of FeCl3 and 0.39 grams of FeSO4*7H2O was added to the flask and stirred until the iron parts dissolved.

An error that could have been present during the lab includes not letting the zinc react completely with the chloride ions by removing the penny too early from the solution. For instance, the percent error of this lab was 45.6%, which was determined by the subtraction of the theoretical percent of Cu 2.5% and the experimental percent of Cu 3.64% and dividing by the theoretical percent of Cu 2.5%. This experiment showed how reactants react with one another in a solution to drive a chemical reaction and the products that result from the

After a while, a brownish color substance started to form on the three iron nails. We predicted that the brown substance on the nails is copper because the reaction of copper(II) chloride with iron is a single displacement reaction, so copper would be produced. 0.48 grams of iron was used in the reaction because 2.73 grams subtracted by 2.25 grams is 0.48 grams. The 0.48 grams of iron had to be used in the reaction with copper(II) chloride in order to produce copper, according to the reaction equation: CuCl2+FeFeCl2+Cu. 0.52 grams of copper was produced after pouring out the copper(II) chloride solution and the three iron

As the compound was reacting, the aluminum pieces were also dissolving, with only a few pieces left inside. The process of the second reaction included the adding of a new substance which consisted of sulfuric acid. The sulfuric acid along with potassium aluminum hydroxide, was yielded to produce aluminum hydroxide, potassium sulfate, and water. This reaction was both a precipitation reaction and an acid-base reaction. Once the sulfuric acid was added, the reaction became very chunky.

The products were aluminum chloride and copper. A change in properties demonstrates that a chemical reaction occurred. One property that changed was the colors. Initially the aluminum foil was a shiny silver, and the copper chloride was a green-blue liquid. After we placed the aluminum into the copper chloride solution, the liquid clouded up a lot and turned to a light grayish hue.

Q1 A reversible reaction is one which can go both ways. Reactants react to form products and products can form the reactants again. Under different conditions the reactants and products can still react but may just become a oneway reaction, however a reversible reaction will eventually reach a point of equilibrium where the products are reactant are produced at the same rate.

Throughout the experiment, copper was altered a total of 5 times, but after the final chemical reaction, solid, elemental copper returned. Each time the solution changed color, a precipitate formed, or when gas appeared, indicated that a chemical reaction was occurring. For the first reaction, copper was added to nitric acid, forming the aqueous copper (II) nitrate (where the copper went), along with liquid water, and

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.
