While strolling through the park you come across this statue of the composer Ludwig van Beethoven. It appears to be made of metal, but its surface is green in color and not very shiny. Is the statue's green color due to green paint or something else? After doing some research, you learn that the statue is made out of bronze, which is a mixture of metals. The statue was never painted. Instead, the exposed surface of the bronze underwent a chemical change, forming a green film over time. You wonder what the film is made of and how it formed. 1) Find the chemical formula of the green film. 2) Are the properties of the film different from the bronze beneath it? Give two examples. 3) Calculate the difference in the electronegativities between the atoms in the green film 4) Do you think this film dissolves in water? What evidence do you have? 5) Is the green film an ionic compound, a covalent compound, or a metal alloy? Explain your answer.

Question 8 of 190 FINAL - Science The question is based on the following passage. Although water is the most common hydrogen-oxygen compound, hydrogen and oxygen form another compound called hydrogen peroxide, H202. Hydrogen peroxide was first obtained by treating barium peroxide with an acid. Very small quantities of hydrogen peroxide are present in dew, rain, and snow because of the action of ultraviolet light on oxygen and water vapor. Hydrogen peroxide has many different applications, depending upon its concentration. A 3 percent solution is used in the home as a mild antiseptic and germicide. A 30 percent solution is used in industry as a bleaching agent because of the permanency of the whiteness it produces. Concentrations of 90 percent are used as oxidizing agents in rockets and high explosives. According to the information in the passage, what can we predict that adding water to an industrial-strength hydrogen peroxide solution will result in? A. an antiseptic B. an explosion…

Lead (Pb) is a heavy metal which has a leaching rate of about 0.0012 mg/L per year. Consider a lake which has a volume of 2.25 x 10^9 L, and initially contains 0.002 kg of Pb. Determine the amount of Pb (in kg) present in the lake after 5.0 years assuming that there is no evaporation of water from the lake’s surface.
