Experiment Kit" (item # 3053439) from Edmund Scientific at scientificsonline.com Add one scoop each of luminol and perborate mixtures and a few copper sulfate crystals to each cup. Add a consistent amount of each chemical. Try to count the grains of copper sulfate so that you are adding close to the same amount to each reaction. As an option‚ premix the dry ingredients in a clean‚ dry container. Add enough luminol‚ perborate‚ and copper sulfate for 10 reactions. This will minimize variation that could

It also includes certain side effects of medications and what medical staff and patients need to be aware of when taking and administrating certain drugs. Pharmacists learn a great deal about this when in pharmacy school. It is very important to know about all aspects of medications especially in a hospital

people. They see should all look at the chemical and physical appearance. My claim is the the mystery mixture was Citric acid‚ road salt‚ and baking soda. The reason I thought it was this mixture because of the physical and chemical appearance. I agree with baking soda road salt and citric acid.The baking soda gives the mixture a powdery texture.The road salt are the little pebbles in the mixture. The citric acid is what make the road salt get smaller. The reason i don’t think it was anything else

Unit Project Documenting the Scientific Method Separating Mixtures Project Separating Mixtures: How can you separate salt water to make pure and drinkable fresh water? Design and build a device to separate a mixture of salt water into its components. For example‚ what device could you build to get the most drinkable water from salt water if you were on a stranded island in the middle of the ocean? Gather data on the amount of water collected and the purity of the water‚ which can

British Dictionary’s number one definition of rhetoric is “the study of the technique using language effectively”. (Collins) Interestingly‚ an American version defines it as‚ “(in writing or speech) the undue use of exaggeration or display; bombast.” (Random House) or “language that is intended to influence people and that may not be honest or reasonable” (Merriam Webster) It seems that American’s exaggerate and fib more often‚ and the British apparently are more concerned with language effectiveness

evidence that help conclude that the mystery mixture ( number 8) is composed of citric acid and sodium bicarbonate the same as mixture six . At first when just observing the dry mixtures‚ it was hard to determine which ones were identical to the mystery mixture. In order to figure out which substances combined to make the mystery mixture‚ another process we followed was adding water to the substances and observing the reaction. Adding water to the mixtures resulted in a chemical reaction. The materials
