Sulfuric acid

Empirical Formula Lab Report The purpose of this lab was to determine the empirical formula of copper oxide compound. In the lab, hydrochloric acid and copper oxide compound was mixed until it formed a blue solution. An oxidation-reduction reaction, a reaction in which there is an exchange of electrons between elements, was performed by adding zinc to the solution to displace the copper in copper chloride. Zinc, in this case, was oxidized by losing two electrons (0 → 2+) while copper was reduced

On December 5th, 1952, London began to go through its “I want to resemble a post-apocalyptic city” phase. Smog shrouded the entire city in it’s smothering blanket, and many were hospitalized because of the deadly illnesses they contracted. Others were not as fortunate and turned into one more number on the steadily increasing death toll. Much harm was inflicted onto both the people and environment of London during the worsening conditions of the days that followed the first, and a lesson was learned

Shlomo Akeri Professor: Ansell Pol Sci 186 Flame Retardant Chemicals The chief concern that motivates the authors of the article is the lack of documentation and clarity regarding the toxic level flame retardant chemicals. The factors that raise the levels of specific chemicals to scientific, social movement, and regulatory scrutiny and concern are not well defined. The concern is serious as it the chemicals pose a health threat. The authors advance several theoretical arguments regarding the issue

Group Members: Austin Snyder and Geoff Olson Title: Photoreduction of Fe2+ Effects on salicylic acid and UV radiation Question to study: How to determine the amount of iron (II) in a solution using a Beer’s Law Plot? How to accurately calculate the solubility product constant of iron (II) oxalate using a Concentration vs. Absorbance graph o What does the solubility product constant tell us about iron (II) oxalate? Background Problem: 1.Equation: a.Absorbance = proportionality

of this lab is to observe the chemical changes of multiple single replacement reaction. Materials: Chemicals Laboratory Tools Zinc Chemplate Magnesium Goggles Copper Toothpicks CuSO4 (Copper (II) Sulfate) AgNO3 (Silver Nitrate) HCl (Hydrochloric acid) Procedure: Take a chemplate and put one or two pieces of zinc, copper and magnesium as shown in the figure. Then add 5 to 10 drops of given solutions into each well. Observe the reactions for 10 minutes and record. Data/Observations: Reaction

Analysis/conclusions In conclusion, the charge/roman numeral on copper in copper sulfate is 2+. The percent composition of copper in copper (I) sulfate was 40.58% and in copper (II) sulfate it was 25.46%. Later, I calculated that the percent of copper in the lab was 26.13%. This percent shows that copper (II) sulfate was used in this experiment because 26.13% was closer to 25.46% than 40.58%. If iron (II) sulfate and copper metal is the product of copper (?) sulfate and iron metal, then copper (

Mercury: The element mercury has the chemical symbol Hg; it is a silver colour and is a liquid at room temperature. Mercury has a high density and surface tension and can easily break up into small droplets. Mercury can dissolve some metals resulting in amalgams, metal alloys of mercury. It is not soluble in water or most other liquids, but will dissolve in lipids (fats and oils). With fluctuations in temperature, mercury expands and contracts evenly with these changes and is classed as a non-combustible

Stoichiometry 04/09/12 Chemistry I B Ms. Norton Introduction/Pre-laboratory Assignment: 1. Write out and balance each of the following equations. A. CuSO4 + Fe Cu + FeSO4 B. 3CuSO4 + 2Fe 3Cu + Fe(SO4)3 2. If Iron (III) Sulfate were formed, what mass of Copper would be expected and what is the limiting reagent? C. 2.26 g Cu D. Fe 3. If Iron (II) Sulfate were formed, what mass of Copper would be expected and what is the limiting reagent?

In the first reaction, the copper wire reacted with oxygen from the air in the reaction 2Cu(s) + O₂(g) → 2CuO(s). This is apparent because it was observed that copper underwent a chemical reaction, changing color form a shiny orange color to the dark gray color characteristic of copper(II) oxide. Therefore, the product of this reaction is copper(II) oxide. The reaction is a synthesis reaction because copper and oxygen combine to form one compound.     In the second reaction, when the magnesium ribbon

Uses of sulphuric acid Sulphuric acid is a very useful, referred as universal chemical because it is a commonly used chemical in the world and is used in a lot of manufacturing industries, for example, car battery, manufacturing fertilisers, refining crude oil, making phosphoric acid etc. This chemical is also known as one of the most important industrial chemical. This acid has helped us in many ways, making things easier for us. What is sulphuric acid? Sulphuric acid is a chemical compound
