ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

Hypothesis: If pH is increased or decreased past the enzyme’s optimum pH‚ the number of products produced by the enzyme will decrease because the enzyme will become denatured. Variables: The Independent variable is the pH of the environment. The uncertainty of pH is ± 1. pH is a unitless value. The Dependent variable is the number of products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant

First thing is to make your hypothesis on how to filter dirty water like mine “My hypothesis is if I use one cut bottle and layer it to be pebbles‚ sand‚ cloth‚ charcoal‚ then cloth‚ sand‚ and pebbles it filter the water will be cleaned.”. Then you start to build hypothesis‚ so start by getting a bottle‚ cut the bottom of the bottle like two inches of it. You take the cap off the bottle then get two coffee filter and use two rubber bands to tie it to the cap of the bottom. Then add about a inch of

In order to determine the acidity of certain substances‚ we used moist and dry pH paper (litmus tests)‚ and observed the results. First we used dry pH paper to test the acidity of household ammonia‚ and it turned yellow. According to the legend‚ this indicates a weak acid. This is‚ however‚ not accurate as the vapor of the household ammonia wasn’t able to react as strongly with the pH paper since it was dry. Then‚ we used moist DI water pH paper with the same substance‚ household ammonia‚ and it

Geographical Indicators application process in India Darjeeling Tea was the first good to be registered as a GI good in India. The need for Darjeeling Tea to get GI protection became pronounced when it was discovered that the volume of Darjeeling Tea being sold in international market was more than the volume being produced. This made it clear that gross misappropriation by way of free riding on the brand reputation of Darjeeling Tea was taking place in the international market. The move for

way a person acts‚ thinks‚ and feels. Measuring personality can use various different scales and many are self-report measurements. It can be difficult to decide which measurement to use for personality type. This study used the Meyer-Briggs Type Indicator (MBTI). We chose the MBTI because of how well known and reliable it has proven to be. Macdonald‚ Anderson‚ Tsagarakis‚ and Holland (1994) conducted a study to see the differences between the NEO Personality Inventory (NEO-PI)‚ and the MBTI. The conclusions

This simulation paper will show what some hospitals have to do to keep costs down. In addition‚ it will analyze financial indicators for decision making. This simulation will also show the financial accounting from a Cardiac Care Hospital’s Perspective. It will show how to bridge a working capital shortage‚ evaluate funding options for acquiring medical equipment‚ and evaluate

MICROCONTROLLER BASED ANESTHESIA INJECTOR ABSTRACT In the hospitals when any major operation is performed‚ the patient must be in anesthetize condition. If the operation lasts for a long time‚ say for suppose for 4 or 5 hours‚ complete dose of anesthesia cannot be administered in a single stroke. It may lead to the patient’s death. If lower amount of anesthesia is administered‚ the patient may wakeup at the middle of the operation. To avoid this‚ the anesthetist
