nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are based on the mass of a product‚ this procedure is classified as a gravimetric analysis. Silver and copper are very nonreactive metals. Neither will dissolve in hydrochloric acid or sulfuric

Green Chris Christopher is in his last year of his degree in Agrobiology. He needs to complete a 6 months internship with the Agri-food and Veterinary Authority AVA of Singapore. He has prior experience in growing crops of tomato and achieving at least a 95% yield. In the lab‚ his supervisor Dr Ong decided to challenge him. Dr Ong said: “Hi Christopher‚ welcome to our AVA laboratory. We are pleased to have you here. We have some problems growing Rhododendron.” Christopher replied: “Thank you

are located all over the United States as well as in many other developed countries. Many companies refuse to report what chemicals are used and produced by hydraulic fracking. Some of the common ones used are nitrilotriacetic acid‚ hydrofluoric acid‚ benzene‚ and sulfuric acid. Each of these toxic chemicals when breathed or even ingested through contaminated groundwater sources near the drills can cause irreversible damage on the humans and animals in the area. Because the fracking goes on underground
