The History and Context of Club Culture "History is hard to know because of all the hired bullshit, but even without being sure of history it seems entirely reasonable that every now and then the energy of a whole generation comes to a head in a long fine flash, for reasons that nobody really understands at the time, and which never explain, in retrospect, what really happened" (Hunter.S.Thompson, "Fear and Loathing in Las Vegas") The late 1980's saw the emergence of a hugely
Acids and bases are not just in use in a laboratory, they come into play in the every-day, they are important to know, with respect to consumer and food products. PH scale, the potential for hydrogen ion concentration, is important because it pertains to the spectrum of acids and bases. Acids are an H+ donor and bases are a H+ acceptor. We can further identify acids by its sour taste, it turns litmus paper red, and it dissolves metals such as zinc or iron. Bases taste bitter, they turn litmus paper
products can be acidic, bases or neutral. It was very interesting to learn that many acids are not dangerous. Some are even found in the food that we eat. Any food that taste sour is acidic. Bases are also found in common household products. They can be very strong and dangerous or weak and safer for use around the house. 2.

Make a lip balm 3 out of a type of nut oil and yellow, acid fruit liquid from fruit, and (medical) rubbing your lips with that every night for a few minutes before going to bed.

for cell activities. They house the respiratory enzymes that convert oxygen and the products of fat, carbohydrate, and protein metabolism into adenosine triphosphate (ATP) and guanosine triphosphate (GTP), chemicals that have high-energy bonds. They are hollow all except for a folded line of matter that contains the ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) of the cell. Mitochondrion make use of a process known as oxidation to make fat acids and pyruvate acid into (indirectly) ATP and
that the liquid with the lowest pH level; Sprite, would have the quickest corrosion rate. Dana Puti Vinegar had the quickest corrosion rate proving the statement wrong, it was discovered that it contains ethanoic acid; acid containing twice the amount of carbon dioxide than a regular acid. To further understand this topic, future research could include; how does the amount of liquid incorporated affect the corrosion rate, how does the temperature of the liquid affect the corrosion rate, and how does
your home a shampoo of beer. If you hate to do this, you can buy the finished product. In supermarkets, you can find a range of products based on this beverage. The world today has become a trend that big brewers collaborate with renowned cosmetic houses with the aim of producing unique shampoo. Beer, for example, straight hair is also good, because it gives the airy effect. Succeeding raise the hair so that it will operate hairstyle richer and fresher. The use of face and skin while
of mixing various levels of acids and bases to see which combination would have the most explosive reaction, and measure the resulting pH levels. I did this by testing an assortment of different pH levels of acids and bases, mixing them together and measuring the results. Most of the experiments resulted in a pH neutral solution, except for the Sulfuric Acid and the Sodium Hydroxide. By far, the Sulfuric Acid was the most explosive, followed by the Citric and Acetic acid. Introduction The project
When approaching the topic of hair chemistry, one may think about the question, where does hair come from? Saclike holes called follicles are located all over the human body. At the bottom of these follicles are a cluster of papilla responsible for the growth of hair. As the papilla, otherwise known as hair bulbs reproduce to make new hair cells, the old ones are pushed up towards the surface of the skin causing the hair to grow longer. This may seem like a simple concept to grasp. However, the process
of soda, is sodium bicarbonate. (Baker Bettie, 2013) Sodium bicarbonate has a high pH, that when incorporated with another acid will react quickly. Although carbon dioxide, is created when baking soda is combined with an acid with low pH. Baking soda will make cookies rise during the baking process, once it reacts with an acid. There must be a common acid (examples of acids are: buttermilk, sour cream, citrus juice, vinegar, and cream of tartar) added to the recipe to produce CO2 if the baking soda
As you may know, when you mix baking soda and vinegar there is a big reaction, but have you ever wondered how this reaction happens? Well in order to find out how it happens you will need to know the elements that make up baking soda and vinegar. You will also learn why these elements are where they are on the periodic table and what is released during the baking soda and vinegar reaction. Baking soda is made out of sodium, carbon, and 2 oxygens while vinegar is made up of 4 hydrogens, 3 carbons
Boats and motorized watercraft are great for a fun day on the lake, but how fun are they for the diverse ecosystems living just beneath the hull of your boat? Boat exhaust and small traces of gasoline and oil are emitted into the waters when motorized watercraft are running. Boats have been shown to affect water clarity and can be a source of algal growth in aquatic ecosystems. The toxins emitted from boats can add chemicals to the water. Certain amounts of the fuel that is in motors is discharged
1. Definition of Acid and Bases: 1.1 Arrhenius definition of acid and base: Arrhenius Acid: The substance or a compound which gives H+ ions in aqueous solution Arrhenius base: Base is a substance or compound that produces OH- ions in aqueous solutions. Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous solutions. It did not take longer
The bicarbonate then reacts with the hydrogen from the citric acid, and this reaction makes water and carbon dioxide. By mixing water with the Alka-Seltzer® tablet, the whole reaction process is started, and that process ultimately results in bubbles of carbon dioxide gas being given off. When the film canister is
an excess of acid or alkali. Typically, these imbalances can be caused by many underlying conditions and or diseases. Normal blood pH levels in blood must be maintained within a narrow range of 7.35-7.45 to ensure that metabolic process is functioning properly and is producing the correct amount of oxygen to the tissues (Healthline.com, 2012). For both Respiratory Alkalosis and Acidosis the kidneys play a part. Normal body functions and metabolism generate large quantities of acids that must be
Metals are degraded through the principle of corrosion. Corrosion is defined as “the gradual destruction of materials chemical or electrochemical reaction with their environment.” The most common form of corrosion is the oxidation of iron, which is commonly known as rust, this is orange in colour and is the most common form of corrosion in everyday life. Corrosion is a natural process, which converts a material to a chemically-stable form such as its oxide, hydroxide or sulphide. It is a gradual
below the lower limit of normal and the serum pH is alkalemic. Chronic respiratory alkalosis is when the PaCO2 level is below the lower limit of normal, but the pH level is relatively normal or near normal. Respiratory alkalosis is the most common acid-base abnormality observed in patients who are critically ill. It is associated with numerous illnesses and is a common finding in patients on mechanical ventilation. Many cardiac and pulmonary disorders can occur with respiratory alkalosis. When respiratory

such as nitrogen, phosphorus, and potassium, are less available below a pH of 6.0. Iron, manganese, and phosphorus are less available when a pH level exceeds 7.5. Most garden plants grow well in slightly acid to neutral soil. This means the pH levels will range from 6.0 to 7.0. If soil is too acid, adding an alkaline material can neutralize it. This is a process commonly called liming. The most common liming material is ground limestone. If soil is too basic, adding a source of acidity will be beneficial
