DESCRIPTIVE TITLE The Effect of Different Amounts of Sodium Chloride on the displacement of oxygen. INTRODUCTION The dependability of the rate of an enzyme-mediated reaction is based on two factors: the substrate concentration and the concentration and action of the enzyme that catalyzes the reaction (Vander, et. al., 2001). Enzymes are catalysts that produce chemical reactions in cells. Enzymes which are large proteins perform a reaction which acts upon a substance known as a substrate. When
Title: Would increasing the amount of rock salt in the production of ice cream, create a more usable ice cream? Purpose: This experiment was used to see if there was a correlation between the amount of rock salt and the height of an ice cream structure. Background Information: Rock salt or “halite” (Rubin, Ken) is a variation of salt or NaCl. Rock salt is formed when salt water is evaporated, leavening behind positive Na atoms and negative Cl ions. You can find Rock salt in many places like
H2O every time I lower the concentration of sodium thiosulphate by 10cm3. I will observe the 8 experiments repeated 3 times each. Each experiment I will have different amounts of concentration of sodium thiosulphate starting with 90cm3 and I will keep a constant amount of HCL of 10cm3 and I will also add different amounts of H2O starting with 10cm3 and increasing as the concentration of sodium thiosulphate decreases. How am I going to make it a fair test I will use a clean flask for every
Executive Statement A mainframe is a very large, powerful, dedicated, multi-tasking computer where enormous amounts of data are processed, sometimes millions of records a day. The mainframe is set up for specific applications and those applications only; which is totally different from a Personal Computer (PC). A mainframe runs a custom operating system specifically written for particular applications while a PC has a generic operating system such as Windows and is built to handle many different
are essential to all body systems. The six classes are water, minerals, vitamins, proteins, fats, and carbohydrates. Most anyone, who swallows food throughout the day, has these kinds of nutrients; however, most people ingest them in the wrong amounts or with excess food that is useless. Water is the most important of all the nutrients. An athlete depends on water. Water is necessary for all energy production in the body, temperature control, and elimination of the by-products of respiration
the newspaper beneath the flask can no longer be read. Both the Sodium Thiosulphate and the Hydrochloric acid are soluble in water, so the concentration of either can be changed. However I am going to use varying amounts of Sodium Thiosulphate acid and H2O but I will keep the amount of Hydrochloric Acid constant. This is difficult factor to investigate as the readings are recorded by human reactions, which could differ due to the inevitabilities of a human error. According to the collision
that the experiment is fair and that different cans may be of different thicknesses so allowing different amounts of heat through. I will keep the amount of water that I put inside the tin can, the same for each experiment to be fair. I will decide on this amount from my preliminary experiment. The time for each experiment will also be kept the same to ensure the water has had equal amounts of time for it to heat up, again I will decide on the time from my preliminary experiment. The independent
An Investigation on Burning Food Planning Aim: The aim of this experiment is to determine the effect of differing amounts of fat in the food on the amount of energy per gram or 100 grams in the food. Scientific Knowledge: Here is the table of quantities of different nutrients in food: Type of food Sunflower seeds Pumpkin seeds Pasta Plain crisps Crisp bread Dried peas KJ energy in food 2518 2527 1470 2214 1280 1265 Protein in food 19
The Meat Industry The cattle industry produces vast amounts of strain in the environment. It is energy inefficient, pollutes water, occupies many acres of land, and deteriorates the health of the people who abuse its consumption. The government subsidizes this industry. Therefore, the price paid for meat doesn’t reflect the environmental hazards involved in the process. In order to protect our health and the health of the environment we should pay close attention to our food choices and make sure
over 3 weeks to find out the effect light has on the growth of pea plants. It will take place in an environment with controlled light, with equal amounts of plants being grown in the light and in the dark. All elements of the experiment other than light will be kept the same, such as amount of seeds in each pot, amount of soil in each pot and amount of water given to each plant each day. This will ensure a fair experiment. Prediction: I predict that in general, the plants grown in the light
Biodiversity is different is each part of the world. Not every part of the world contains the same amount of creatures yet there are parts of the world that might contain similar amounts. These regions of the world have similar weather patterns and therefore similar species will develop there but they are not necessarily the same. One of the more important regions of the world that contain a large amount of biodiversity is the tropical rainforest region. “The forests comprise roughly 7% of the dry land
sleep on any given night. We drink copious amounts of caffeine in order to stay awake and finish that paper. Many times, we compensate for a lack of sleep at night by taking naps after (and sometimes during) our classes. This behavior might be recognized as "normal" by many teenagers and young people. However, many college-aged people suffer from sleep disorders. The most commonly recognized among these is insomnia, or the inability to obtain an adequate amount of sleep. But often overlooked and potentially
on the play. “…his focus is on his grief and the profound impact in which the ghost has upon it. (Hamlet pg.18 paragraph 3) I strongly agree with this statement because Hamlet is continually showing huge amounts of grief throughout the play. Even in his opening words in the play he shows some amount of grief to his uncle, the new king, and his mother. His mother basically says that his father is dead, and that there is no bringing him back. So what good does it do for him to weep and mourn? Hamlet
Investigating Temperature Change when Different Volumes of Acid and Alkali are Mixed Prediction ========== My prediction is that the biggest temperature change will be when there are equal amounts of H+ ions and OH-, this is because create an optimum mixture for the ions to neutralise each other.

at a very young age? Soda is a sweetened, carbonated, acidic, often caffeinated drink. Forty-five gallons of soda is consumed per person/per year by the average American. Even adults are just as vulnerable to tooth decay, from drinking excessive amounts of soda, even though they have good enamel and well calcified teeth. In America soda manufacturers are the biggest users of sugar. At least ten teaspoons are in each, 12 ounce, can which provides you with the maximum recommended intake of sugar
support, both financial and mental, is instrumental in achieving a college education, and should be given in equal amounts to both athletic and artistic students. But each year, numerous athletes around the United States are offered college scholarships to recognize them for their talent and to encourage them to play at the university awarding the scholarship. At the same time, the same amount of equally artistically talented students are left to pay for college themselves because they are not offered
tourist towns. These towns are typically small and thrive on the abundant amounts of tourist activity flowing through the city every year. One such city is Red Lodge, Montana. Red Lodge, Montana is a thriving community of 1,875 “nestled at the foot of the very rugged and scenic Beartooth Mountains”. While the number of residents compares too many small towns in North Dakota, the difference spurs for the abundant amount of tourist activity drawn through the small town. Tourists come from all around
combination consists of all the letters being different. I will also try and find a formula for this arrangement, and number of letters. Once I have discovered these formulae I am going to investigate, other combinations of letters and different amounts of letters. I will then try to discover a link between the formulae to enable me to find a formula for the general case.

He finds support for it on three main arguments: first is the fact that the government is spending huge amounts of money and it is not solving the violence problem; second because people agree with it and actually want it back to schools, and finally because the freedom of religion is guaranteed by the Constitution. Throughout his arguments becomes to see that instead of spending that amount of money to combat the crime, it is cheaper and better effective to use God and religion as a weapon against
offer many perks to its customers, such as substantially better customer service, as well as convenience. Yet even though this may be true. Wal-Mart’s low prices have seemed to be far superior in generating revenue that has translated into enormous amounts of profits. So this is why now Albertson’s figures that if they cannot beat them on price then they will do it through information technology. One of the ways that Albertson’s has implemented information technology into their business strategy is
