Precipitation reaction, or otherwise known as double-replacement reaction, is one of the three common types of chemical reactions along with decomposition and combustion. A simple definition for the precipitation reaction would be “atoms from two different compounds switch places” (Lew 40). This means that one of the reactant’s molecule “trades” places with another from another compound to form products, like a precipitate, hence the term double-replacement. A precipitate is usually a solid…

a)The five most important biogeochemical cycles are the oxygen cycle, nitrogen cycle, carbon cycle, sulphur cycle and the sedentary cycle. These five cycles can be classified into pools. Active pools are free flowing cycles controlled by life processes such as photosynthesis. Storage pools are segregated bodies controlled by physical processes such as, volcanic eruptions or earthquakes. Oxygen cycles through the environment in three major forms; gaseous atomic oxygen, and the…

Potassium is everywhere. It races through the bloodstream, drifts in the air, swims through the water, and rises up roots of plants. Furthermore, it is vital for life to exist on earth, from the grass lions, bears, and humans trample on every day, to the fish and plankton in the ocean. Without potassium, the ninetieth element on the periodic table with chemical symbol “K,” life would be immensely different today, notwithstanding any in the first place. Potassium functions a significant role in…

When carbon dioxide is dissolved in blood, it forms carbonic acid, bicarbonate ions, and carbon dioxide. All three exist in equilibrium. As levels of carbon dioxide increase, the equilibrium of the carbonate buffer shifts making more carbonic acid. Hydrogen ions increase thus shifting the equilibrium left, and therefore bicarbonate accepts hydrogen ions and increases carbonic acid. This creates a homeostasis imbalance within the body. There are…

NASCAR is one of the world’s most popular sports attracting millions of viewers every Sunday to watch their favorite drivers race hundreds of miles across the race track at intense speeds. Many people who love to tune in and watch the sport are not aware of the chemistry behind NASCAR. For the cars to be able to operate the way they do, a lot has to go into building them. Each track that is raced on brings different challenges to the race team whose job is trying to get their car to be the…

Discovering Microbes In A Mini Ecosystem Introduction: Every ecological environment provides with distinct nutrients that allows certain microorganism to survive and grow. Sergei Winogradsky, a Russian microbiologist, developed the Winogradsky Column to grow and investigate microorganisms in a complex biofilm communities. This column will grow different microbes at different gradients that will appear on the column. Depending on the various concentrations of nutrients, choice of soil and water…

The objective for this report is to explain all the failures that might occur while making Pyrex and what are the cure that will help to prevent all of the causes and failures. Corning Inc. introduced Pyrex cookware in the market. Later, Pyrex was expanded to make clear and opal ware objects. Pyrex has a unique property that is Lower thermal expansion. Pyrex cookware is mostly made of borosilicate but it was later replaced by soda lime glass because that has a strong mechanical strength. Another…

In South Australia the Pyrite mine (iron sulfide) initially began in the mid 1950’s and the mining operations stopped and closed at the end of 1972. The production of iron sulfide was to manufacture and create fertilizers such as, superphosphate fertilizer. Superphosphate fertilizer is used in agriculture where is helps to sustain the rapid change of social economic after WWII. (http://www.minerals.statedevelopment.sa.gov.au/mining/former_mines/brukunga_mine_site/brukunga_mine_site ) After the…

What is acid rain? Acid rain is a form of deposition in which chemicals with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7,…

FOOD COLORS INTRODUCTION: Through pigments we observe the different colors at each step of our lives, because the pigments can be found in each organism in the world and plants are the main producers. Pigments can be easily found in fruits, vegetables and flowers. It can also be found in skin, eyes and in other complex body parts. Natural and synthetic pigments are used in food, furniture, cosmetics and other products. Natural pigment plays an important part in photosynthesis. The food colors…
