Introduction The purpose today’s experiment was to test out the concepts of moles, mass, and atoms by separating two metals. The galvanized iron was measured to two decimal places in centimeters then weighed for mass to three decimal places in grams. The galvanized iron was then stripped of it’s layer of zinc by using hydrochloric acid. The chemical reaction of the experiment is shown below: 2 HCl (aq) + Zn(s)----> H2 (g) + Zn2+(aq) + 2 Cl-(aq) Once the iron was free of the zinc…

Since the industrial revolution fuels have been used for power. Fossil fuels are organic matter made from remains of flora and fauna which has been subjected to immense pressure and heat deep within the earth over millions of years. Now fuels such as petroleum are used to power vehicles such as cars airplanes and ships (Mitshibishi Heavy Industries, 2015). Fuels are products that are burned to release energy in the form of heat or power, fuels are made out of coal, oil, natural gas, and wood and…

(such as diamonds or coal), liquid (such as oil) or gases (such as carbon dioxide) Through photosynthesis, plants absorb carbon dioxide from the atmosphere and release oxygen. Carbon dioxide into carbon compounds make the health of plants, they are stored in the aboveground and underground parts of plants. Animals eat the plants, oxygen and exhale, exhale carbon dioxide. Carbon dioxide consists of animals and for use by plants during photosynthesis. Storage not being eaten by animals ultimate…

Bunker Fuel Investigation The effect of bunker fuels on the Port Adelaide area. Introduction Bunker fuel is a form of crude oil which is left over from the refining process of petroleum. Bunker fuel is typically a very thick sludge because of the large amount of impurities such as sulfur and nitrogen. These impurities make bunker fuel extremely cheap for ship operators, but has a much more negative effect on the environment, as when the fuel is burnt the impurities are released into the…

In our experiment we evaluated which liquid yeast would produce gas the fastest by measuring how long it took for certain liquids to inflate a balloon. We hypothesized that if the yeast and sugar were placed in a warm,sugary environment like apple juice, then the yeast will produce more CO2 and cause the balloon to inflate faster. The control was the room temperature Throughout the experiment the type of balloons, size of the erlenmeyer flasks, amount of yeast, volume of each liquid, and the…

Oaks trees (Quercus species) have adaptations to withstand drought but the trade off of those adaptations is multiple long-term negative effects on photosynthesis. These adaptations help to tolerate harsh conditions, specifically in drought. In situations of long periods of drought it has been researched that oak trees lose their ability to effectively perform photosynthesis. Photosynthesis is the process in which sunlight is converted in to chemical energy. Plants make their own food by using…

Molds are known to be harmful and they indeed are. They can bring numerous negative effects to health and to the house or building structure itself. As they can grow to almost anything, they can bring damage to any home item or surface too. And this only marks just how important it is to conduct a mold removal process especially if it is black mold infestation that has to be dealt with. Of all the types of indoor fungi, black molds, known as Strachybotrys atra, is the most infamous. It is…

Despite the east coast’s recent snowstorm, it looks like spring will be arriving early this year, as predicted by Pennsylvania’s most famous groundhog, Punxsutawney Phil. On the morning of February 2nd, Phil emerged from his tree trunk cage. As he was placed on top of the tree trunk, his actions, interpreted by The Groundhog Club’s emcee, depicted that Phil did not see his shadow. The emcee then announced “ There is no shadow to be cast! An early spring is my forecast!” as Punxsutawney Phil’s…

Lynn White Jr. offers an important assessment and critique of Western culture and its’ effects on the environment in “The Historical Roots of Our Ecological Crisis”. Throughout the short essay he brings to light the ways in which Westerner’s anthropocentric lifestyles and suppositional inherent place at the top of the food chain has had a profound and disastrous affect on the natural world in the late 20th and early 21st centuries. Because the timeline of the natural world is understood…

The uptake of oxygen into muscles is what facilitates muscle contraction. Oxygen that is obtained through breathing by the lungs is transported to the rest of the body, as well as the heart by means of haemoglobin. The rate of liberation of oxygen from haemoglobin has an effect on the quantity of oxygen available in the muscles for a muscle contraction to ensue. The higher the oxygen concentration in the muscle the greater the force of muscle contraction. Temperature has an effect on the…
