The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

Given that mass was lost from the copper carbonate hydrate during heating, in this decomposition reaction, how many moles of solid product were produced? The molecular weight of the solid product is 79.545 g/mol (moles = mass / molecular weight). There were 4.183 x 10^-20 of solid product produced 4. Copper carbonate hydrate produces 1 mole of water (MW = 18.015 g/mol) was for every mole of solid product (MW = 79.545 g/mol) produced.

For the unknown phase two project, I was assigned unknown number one. After many tests, I came to the conclusion that my unknown was Acinetobacter baumannii. It had cultural characteristics of yellow or clear colony pigmentation, smooth and translucent surface, circular form, smooth margin, and flat elevation. The unknown’s broth properties included a ring, turbidity, and sediment.
Percent Cu2 + In A Mineral Sample

As for the rock portion of the experiment, the students concluded that the mass percent of copper was 3.1%. This mass percent of Cu2+ is above the accepted value of 1.0 percent copper, which is the economically viable percent for mining copper ore. From this value of 1% copper in copper ore manufacturers can extract 9.99% pure copper (Copper Mining and Processing: What is Copper?, n.d.). These results show that the provided sample of copper ore would be worth mining, since it contains a higher percent of cu2+ than is needed to mine for copper. Overall, the experiment was accurate in determining the mass percent of cu2+ in the rock sample.

The same metal was placed in vertical columns in an effort to organize the metals. Groups moved to each solution labeled and covered the metal in the respective solution. Observations to how each metal reacted to a solution were then recorded. Each metal was covered in five different solution compounds. Unless the metal and the solution compound contained the same element, such as iron and iron (III) chloride.
Reversible Reaction Lab Report

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

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.

In this experiment, the evolution of the copper cycle was observed through a series of reactions. Four different copper compounds are formed through different reactions to inevitably lead to the recovery of Cu(s). This primary goal of this experiment was to study the Law of Conservation of Mass and perform 5 reactions on copper compounds. As Jenna Winterberg states in her book “Conservation of Mass,” the first part of this law is that mass or matter cannot be created. The second part of the law is that mass or matter cannot be destroyed .

Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of

Applesauce lab report Sarah Azmal, Tillman Mcfadden Problem: A Connecticut company is in the business of making and selling apple juice therefore they need us to see which enzymes is the better choice for them, which enzymes produces more apple juice and the cost effectiveness. Hypothesis: If the enzyme, Pectinase, is added to applesauce, then more juice will be extracted than if Cellulase were added because Pectin holds the cell wall together and if it is separated apart from each other, then more juice would be able to flow out.

Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

Lab Report Experiment 6 Rates of Chemical Reactions By Nikhola Mirashirova Lab Partner: Dina Abetova Section 3, Saturday October 31, 2015 Introduction Rate reaction is the measure of the change in concentration of the reactants or the change in concentration of the products per unit time.1,2 Rate law for this experiment: Rate = k(I-)m(BrO3-)n(H+)p There are several factors which affect the rate of reaction: catalyst, reactant concentration, and temperature.1,2 A catalyst is a substance that changes, increases or decreases, the rate of a chemical reaction but is not being used up during the reaction.3 It provides an alternative way, so that the rate of reaction changes.4 Catalyst, which is used in this experiment, is (NH4)2MoO (0.5 M).
