Glasgow coma scale is a neurological scale which is used in assessing the level of consciousness of a person the initial score of a person is taken and recorded and this is compared with the subsequent score of the person. This is done to note if the patient is improving or deteriorating. The scoring is made based on certain criteria and a score of 3-15 is made. The score 3 indicates deep unconsciousness while the score 15 indicates full consciousness. The Glasgow coma scale was published in 1974

To find out if the manufactures claim on Sensodyne toothpaste is the correct level of pH. I expect the Sensodyne toothpaste to be a neutral pH level as the manufactures claim that this products pH level is neutral

Alloy - An alloy is a substance made by melting two or more elements together‚ at least one of them a metal. An Example: Examples of alloys include brass‚ bronze‚ 14k gold‚ and sterling silver. covalent bond - A covalent bond is a chemical link between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms

Chrysler also known as Americas ‘Big Three’ automobile companies are located in this city. The concept of External Scale Economies can help us explain why these three major companies are located in this area. Scales economies are important for a country because they represent a growth in its economy. Companies are able to produce more products or services at a lower cost of input. “External scale economies are based on the size of an entire industry within a specific geographic area.”1 These companies bulk

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

------------------------------------------------- COLORIMETRIC DETERMINATION OF pH ------------------------------------------------- Abstract This experiment examined the result of the various color indicators combined with different buffer solution‚ thereby testing the precision and accuracy of determining the pH value colorimetrically. Colorimetric method is a simple and practical procedure with an important advantage: they do not get out of order as from time to time do the pH-meters. Four buffers (Acetate buffer‚ phosphate

analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels may change if other solutions are added‚ we can tell what the pH will be based on its colour. Solutions called buffers change the pH levels of

Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of colors depending on its pH level was

Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best results when testing the pH within a solution. The pH‚ which stands for the proportion of hydrogen ions in a solution‚ could be acidic (acidosis)‚ neutral or basic (alkaline). The pH scale goes from numbers 1 through 14. A pH of 7 is neutral; meaning the amount of hydrogen
