1. Iron (IIII) and copper (II) sulfate solution Fill a small test tube halfway with copper (II) sulfate solution. Add a 2.0 gram iron rod to the solution and observe the reaction. 2 Fe + 3 CuSO4 = 3 Cu + Fe2(SO4)3 The new product is iron (III) sulfate‚ it contains the Fe 3+ ion which is brown. Lead (II) nitrate and potassium iodide solutions Pour about 2.0 mL of lead (II) nitrate into the test tube. Add 5 to 10 drops of potassium iodide solution to the test tube and record your observations

observational activity on an article I found titled “After Death: 8 Burial Alternatives That Are Going Mainstream.” I randomly stumbled upon this article after researching eco-friendly/bio-degradable caskets and “natural” cemeteries. This article discusses eight ways a person’s body can be buried or rather handled after death that are not mainstream (ex. wood casket placed in a cement vault or cremation.) One alternative mentioned is resomation. Anderson-McQueen funeral home in St. Petersburg‚

disaster‚ but don’t be scared. Like most things we can fix this situation we have put ourselves into with alternative energy sources. Sorry Captain Planet it looks like you will be sitting this one out. There are many different forms of clean and renewable alternative energy. Fortunately it look likes we may be headed down the right path to saving humanity. Some of these forms of alternative energy that can definitely help solve the problem are: wind energy; hydrogen; solar power; wave energy.

Haroon Saddique Alternative Punishment One alternate punishment instead of prison could be higher education. Instead of focusing on vocational programs‚ we could pick out prisoners with some type of college experience and offer them an opportunity to complete an AA/AS or BA/BS program at a local educational facility. I believe that some prisoners are ok with going to a vocational program and getting a job. But if they are not happy with the job they get‚ or the money they make‚ they might

Scuba diving is a form of underwater diving in which a diver uses a scuba set to breathe underwater. According to the Professional Association of Diving Instructor (PADI)‚ a “DEEP DIVE” is considered to be anything from 18 meters (60 ft) to 30 meters (100 ft).
