The first step of the creation of verdigris was preformed using the following reaction (1):
4CuSO4*5H2O(aq) + 6NH3(aq) CuSO4*3Cu(OH)2(s) + 3(NH4)2SO4(aq) + 14H2O(l)
Based on this chemical equation, four moles of hydrated copper sulfate reacted with six moles of ammonia to produce a precipitate of copper sulfate tribasic along with aqueous ammonium sulfate and liquid water. It was known that a chemical reaction was occurring when the ammonia was being added via the color change from light blue to dark blue. The precipitate formed from this solution was acquired via vacuum filtration, which involved the solution being separated from the precipitate via air pressure flowing out of the flask. The air pressure flowing out of the flask was caused by a faucet that was running water which was attached to a tube that was attached to the collection flask. …show more content…

It was known that a chemical reaction underwent when copper sulfide tribasic was mixed with aqueous sodium hydroxide when the new observed precipitate of copper hydroxide was formed.
This precipitate of copper hydroxide was then required for the final step of verdigris synthesis that is represented by the following equation

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

Introduction Paramecia is a unicellular Protista which are naturally found in aquatic habitats. It is easily cultured in the laboratory. It is oblong shaped and covered with short hairy structure called cilia. Paramecia does not pose any health or ethical concerns and the population can be maintained if there is a food source such as Enterobacter (Biological Foundation 7).

Empirical Formula Of Copper Chloride Lab Report

729 Words | 3 Pages

The objectives of this experiment were to use knowledge of chemical formulas and chemical nomenclature to experimentally determine the empirical formula of copper chloride. Common laboratory techniques were used to conduct a reaction between copper chloride and solid aluminum in order to get rid of the water of hydration. The amount of water of hydration in the sample of copper chloride hydrate was calculated by measuring the mass before and after heating the sample. Afterwards, an oxidation-reduction reaction was conducted, resulting in elemental copper.

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.

In this reaction NaOH was added to the Cu(NO3)2. The solution developed a precipitate which made the clear solution become cloudy and uniform in color (blue). The physical color change was demonstrated through the formation of the precipitate. The third step was the formation of CuO. In this reaction, the Cu(OH)2 product was heated on a hot plate and stirred continuously until the solution became colorless and a dark precipitate formed.

+ H2O (g) Reaction 4: when a sulphuric acid is added to the solution that contains copper (II) oxide, a double displacement reaction will occur. the copper (II) oxide will react with the sulphuric acid producing copper (II) sulfate and water. The copper and hydrogen gas replace each other. Balanced Chemical Equation: CuO (s) + H2SO4 (aq) —> CuSO4 (aq) + H2O (l) Reaction 5: when zinc is added to the copper (II) sulfate solution, a single displacement reaction will occur.

Fermentation is breaking down glucose without any oxygen. But there is a more detailed and complete way of breaking down glucose and that is called cellular respiration. Aerobic respiration is when oxygen is used as the reactant, but an organic fuel is also used. Cellular respiration can have not anaerobic and aerobic processes. When one substance moves electrons completely to a whole different electron is called a redox reaction.

An experiment was conducted in order to determine the oxygen consumption in dry and soaked peas within two different temperatures of water. Cellular respiration is the release of energy by metabolic chemical oxidation in the mitochondria, (DeStefano 2016). The hypothesis was the germinating warm water peas would have the highest rate of oxygen consumption. Within this experiment, a twenty-one degree celsius bath and a six degree celsius bath were set up. Then, a one hundred mL graduated cylinder was filled with fifty mL of water.

Seed type and cellular respiration All cells perform cellular respiration to maintain homeostasis and growth. Plants can produce sugar from suns energy, when they need energy they metabolize stored sugars through cell respiration. Plants need the energy to perform different task such as transportation or growth. Similarly to human cell respiration, cellular respiration rate in plants isn’t always consistent and depends on many other factors. After a seed is dropped from plant it goes into a resting period (dormacy) where the stored energy is released very slowly.

The purpose of this lab was to test the effect of pollution on algae growth. Through a series of experiments that lasted a month, four of the six hypotheses were proven to be correct or partially correct. The first hypothesis stated that if 0.5 mL of salt was added to algae, then the algae would grow slower than the positive control. This was proven correct, as shown by the difference of the data from the positive control and the container with 0.5 mL of salt in it.

Compton scattering is the result of an incident photon with a high energy collides with a loosely bound outer shell electron. The outer shell electron is knocked out of the outer shell and this causes the initial photon to lose some of its energy. This results in a recoil electron and a scattered photon. When the collision happens the scattered photon changes direction and the recoil electron (Compton Electron) is the electron that was once on the outer shell is sent on its own path. The scattered photon’s energy can be calculated by subtracting the recoiled electron from the initial photon’s energy.

Luminol is a chemical that forensic scientists use to find traces of blood at crime scenes. Before application, a crime scene investigator will assemble the solution by combining luminol, sodium hydroxide, and hydrogen peroxide. The sodium hydroxide and hydrogen peroxide are what initially sets off the chemical reaction with the luminol. Then the investigator sprays it over the crime scene. If there is any blood present, the iron in it will act as a catalyst in the chemical reaction.
