Freshwater creek is a freshwater stream located in North Cairns, and flows through the Redlynch area-which consists of rainforest, housing, farming and recreational areas. In order to have an indication of general health levels for Freshwater creek, measurements of the water parameters must be regularly checked. This is done to maintain health and prevent abnormal water qualities. Certain water qualities like dissolved nitrates, ammonia and oxygen will be measured at a site upstream from…

Currently, pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States. Furthermore, the five year survival rate of individuals diagnosed with pancreatic cancer has been estimated at just below 5%. This can be attributed to the fact that pancreatic cancer often progresses stealthily and physical symptoms (jaundice, abdominal pain, and weight loss) do not present until the cancer is in its later stages. As a result, the best way of treating pancreatic cancer is to…

p-Phenacetin was Hydrochloric Acid, which completely dissociates in water due to it being a strong acid. During this reaction the Hydrochloric Acid proton pronated itself to the amino group in p-Phenetidine, thus giving the amino group a positive charge. Next, a small amount of decolorizing carbon was added to the solution and filtered. The decolorizing carbon caused the solution to turn a dark brown color. The decolorizing carbon absorbed the nonpolar molecules in the solution, that is, the…

He was able to find the charge of an electron with an experiment involving passing oil through an electrically charged plate with a hole in the center. Using this newfound charge and the determined mass-to-charge value of an electron, “you obtain an electron mass of 9.109 x 10-31 kg, which is more than 1800 times smaller that the lightest atom” (Ebbing and Gammon, 47)…

The History of the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…

This report will compare the water quality of Freshwater Creek over the last three years using chemistry to show how the three chosen parameters are all linked and affect the overall quality of the water. Water is combination of two atoms, oxygen and hydrogen. When two hydrogen’s bond with one oxygen it makes a covalent bond. A covalent bond relates to the outer shell of electrons (valence shell) being shared with the neighbouring molecule for them to bond. A covalent bond only occurs between…

rest. Keeping with the idea, as the uppermost member of the Halogen Family, fluorine claims the atomic number 9.Though that statement in itself may not seem impressive, the atomic number of fluorine officially describes the nine units of positive charge, called protons, that correspond with nine units of negatively charged electrons. The electrons alone allow fluorine its embellishment, but the protons and electrons together provide stability for fluorine through the creation of neutral…

Ion is a group of atoms which they behave on an electrical charge; there are two types of ions; cation and anion. Cation is a positively charged ion whereas Anion is a negatively charged ion. First ionisation energy- The first ionisation energy is the energy to remove electrons that are unstable from 1 mole of gaseous atoms to gain 1 mole of gaseous ions with a positively charge (1+) As you go down a group, the energy decreases from the top to the bottom due to the shielding effect. When there…

Results and dissection 3.1 Transition metal complexes of the macrocyclic, H6L Ligand 3.1.1 The macrocyclic, H6L Ligand The physical and analytical data of the macrocyclic, H6L ligand and its transition metal complexes were shown in Table 1. From the investigation, the expected structure of H6L with its possible toutomeric forms can be represented as shown in Figure 1. H6L ligand is highly symmetric under the point group C2v symmetry and can show all the normal modes of vibrations by solving…

What is a circuit? How do they work? An electric circuit is a kind of path made up of wires that allows the flow of electrons. The circuit has to be made in a circular form, as the electrons must frequently move in a full loop, in which they will return to their original position and then complete the loop again. (“What is an electric circuit?”) The battery or another source of power provides the voltage, or ‘electrical push’, that makes the electrons move through the circuit. When the electrons…
