Introduction When iron is mixed to Copper (Ⅱ) Chloride; the product will be copper and iron chloride. However‚ in this experiment‚ we do not have the information of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally

Essay #2 Tina Taylor William Jennings Bryan argues against the gold standard. What arguments does he give against the gold standard and why does it oppress the common people? William Jennings Bryan was against the Gold Standard because it artificially lowered inflation. In today’s times the Federal Reserve can print as much money as it wants and also control how the money circulates in the economy by buying and selling bonds. With the gold standard there was an infinite amount of gold that

oxygen increases so does the number of fish observed. However‚ when the dissolved oxygen reaches 14 ppm the number of fish decreases to 10. So‚ 6ppm and 14ppm‚ 8ppm and 16ppm‚ and finally 10ppm and 18ppm‚ have a similar number of fish observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If the amount of dissolved oxygen is increased‚ then the number of fish observed will increase. 3

TITLE: Wad a Watershed Lab INTRODUCTION: Using models is very important in science. In this lab‚ you will design a model that will help you investigate the relationship between land surfaces and water on Earth. OBJECTIVE: To design a model that will help you visualize watershed characteristics. PROBLEM: How can we use the relationships between land surfaces and water to understand conservation of resources and pollution? HYPOTHESIS: In your own words‚ write a hypothesis about how the relationships
