Personal Care period 4 Michelle Manobanda 2012 The FDA permits the use of mercury compounds in eye makeup at concentrations up to 65 parts per million. The preservative thimerosol‚ found in some mascaras‚ is a mercury-containing product. Mercury is associated with a host of health concerns including allergic reactions‚ skin irritation‚ toxicity‚ neurological damage‚ bioacculumation‚ and environmental damage. Mercury readily passes into the body through the skin‚ so normal use of the product

Ashley Huston ILab‚ Week #2 CATIONS AND ANION LAB Introduction The purpose of this lab is to demonstrate a double-replacement reaction of ionic compounds. In this experiment‚ you will combine two ionic compounds. Both compounds are soluble in water. If a response happens between these two compounds‚ then a precipitate will form because one of the two resultant compounds is not soluble in water. This is a hint that a reaction took place. Cations are positively charged ions that are attracted

Entire Review Problems Cumulative- Practice 1. At a certain car wash‚ 40 more cars than vans go through on a typical day. If each car pays $12 and each van pays $16 and the total earned per day is $2244‚ find the number of vans that go through the wash. 2. a) In the Fine Company‚ the CEO must invest in 30% more shares than the CFO. The shares sell for $10.20 each and the total value of the shares owned by the two of them is $132 549. Find the number of shares owned by the CEO.

Jessica Robins Lab 3: Properties of Organic Compounds Introduction Distillation is a physical process used to separate chemicals from a mixture by how easy they vaporize. The temperature rises unit it reaches the temperature of the lowest boiling substance in the mixture while the other contents of the mixture remain in their original phase (until the most volatile substance has all boiled off) as it’s heated. Hot vapor results and passes into a condenser and is then converted to a liquid

heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid. What I already know Magnesium reacts with most

On January 25‚ 1964‚ Bill Bowerman and Phil Knight founded “Blue Ribbon Sports.” Mr. Bowerman and Mr. Knight officially changed the name of their company “Blue Ribbon Sports”‚ to Nike‚ Inc. on May 30‚ 1971. It started out as the two of them selling running shoes from a Japanese manufacturer out of the back of their van. They would park their van outside of track meets and try to sell their running shoes to the athletes. Nike is now headquartered in Beaverton‚ Oregon. To think that Nike came

Title: 03.09 Molar Mass of Compounds: Determining the Formula of a Hydrate Purpose: To determine the formula of a hydrate. Materials: * crucible * Bunsen burner * balance * CuSO4 hydrate Procedure: 1. Measure the mass of the clean‚ empty crucible‚ record the mass. 2. Add one or two scoops of the hydrate to the crucible‚ record the mass. 3. Heat the crucible and hydrate above a Bunsen burner for at least ten minutes to make sure that all of the water evaporates

companies often concentrate the byproduct solutions so that they are easier to dispose of. One particular chemical waste disposal company wishes to utilize these concentrated byproduct solutions to create potentially useful solids (Bauer 45). It was the lab group’s goal to design procedures for creating these useful solids out of the concentrated byproduct solutions. The concentrated byproduct solutions provided by the company were: 0.1 M of NaOH‚ H2SO4‚ BaCl‚ HCl‚ AgNO3‚ and Zn(NO3)2. With the byproduct
