We started the experiment with part 1 of the lab using 0.20 M to find a standard absorbance curve for [FeSCN2+], we found the max absorbance which we would use would be at 432.6nm. Once we had this absorbance, we used that data to create our absorbance vs. concentration graph which was 3635x + 0.0449, with an r2. After this we did part 2 of the lab, where we got 5 different test tubes to measure the absorbance with varying amounts of 0.002 M Fe(NO3)3 and 0.002 M SCN- and H2O, and we subtracted the absorbance of test tubes 1-4 from the absorbance of test tube 1 to get the net absorbance. After this we plugged in the net absorbance from part 2 to the equation from part 1, this result gave us the concentration at equilibrium, so that we could

    You have made it a point to go through the timesheet and DAR book every day to look for errors. Yes, I placed the sticky note and made the pen and ink changes to the projected timesheet that is not submitted to payroll until Friday. That way you will have enough time to see it ask questions or make the necessary changes to the document. We all know that there is going to be a last-minute change to schedule do to the bad last-minute planning of the scheduling. Since there is no one currently filling the 3 to 11 time slot.

    Suppose you need to find the fractional European call and the fractional European put options. Let the Hurst parameter be $H=0.85$, the $\sigma=0,25$, $r=0.10$, $S_{fbm} = 100$, $K = 95$, we have \begin{eqnarray*} d_1^{fBm} & = & \frac{\ln{\frac{S}{K}} + \frac{1}{2}(r( T - t) + \frac{(1)\sigma^2{( T^{2H} - t^{2H})}}{2})}{\sigma{\sqrt{T^{2H} - t^{2H}}}}\\ & = & \frac{\ln(\frac{105}{100}) + (0.10(0.25 -0) + \frac{(1){0.25^2}{0.25^{2(0.85)} - (1)0.25^{2(0.85)}}}{2}}{(0.25){\sqrt{0.25^{2(0.85)} - 0}})} \end{eqnarray*} we obtain $d^{fBm}_1= 1.0558$. We find in the normal distribution that $N(1.0558)= 0.8544$ and $N(-1.0558) = 0.1456.$

    Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

    Introduction of NMR spectroscopy Nuclear Magnetic Resonance (NMR) spectroscopy is a form of absorption spectroscopy by which a nuclei under investigation absorbs the energy from an external magnetic field and resonances or excites from a low energy state to a high energy state. It involves the disintegration of spin state into two spin states of unequal energy. The emerging radiofrequency is absorbed in a magnetic field resulting to the magnetic properties of the nuclei which getting up from the axial spin. Hence, different NMR absorption spectrum can be obtained which contains one to several groups of absorption lines in the radiofrequency part of the electromagnetic spectrum depends on the particular nucleus. Apparently, the location of peaks

    Use these results to determine the product concentration, using Beer-Lambert’s Law: A= ɛCl (where A is the absorbance, ɛ is the molar absorptivity, C is the product concentration and l is the length of solution that the light passes through). Calculate the product concentrations at every minute for 10 minutes for all 7 of the test tubes using Beer-Lambert’s Law. Plot a graph of product concentration vs. time and then use the gradients of the 7 test tubes to determine the velocities of the reaction. After calculating the velocities, plot a Michaelis-Menten graph of velocity vs. substrate concentration.

    Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.
