Calculation

ABSTRACT Within this experiment, the use of a bomb calorimeter was required in order to determine the heat capacity of the system through the combustion of three separate trials of benzoic acid. The resulting heat capacity values for each trial were averaged, with a standard deviation found as well. This was then used to work backwards, for a naphthalene trial, in order to calculate the change in energy (∆U) and the change of enthalpy (∆H). The accepted value for the change in enthalpy of…

Accuracy and Precision Lab Report By Connor MacFarland 10.23.2016 IBC 1 Question What is the difference between accuracy and precision and how can we demonstrate the difference? MATERIALS Pencil Notebook Paper 100 mL Graduated Cylinder 1 Gallon of water Ruler Unmarked Plastic Container 3 different kinds of Rocks of different sizes Triple Beam Balance PROCEDURE Estimating Lengths Procedure A piece of notebook paper was torn into 8 rectangles Without a ruler, a line was drawn which…

Valuation Methodology In order to value Graincorp’s stock, this report used two-stage discounted cash flow (DCF) model. This model is chosen considering that Graincorp is in the mature stage, with the characteristics of paying high dividends and has a high leverage. Moreover, management stated that they are building another silos by this year, so it is assumed that Graincorp will have an increasing growth for several periods and will drop to the stable growth afterwards. Hence, the first stage…

of those “sigfigs” throughout an already strenuous calculation can be a pain. Countless points and half-points have been deducted from tests throughout chemistry’s ages from students claiming that significant figures are, ironically, insignificant. But, let’s consider the following scenario. Joey is in his inorganic chemistry lab. The second step to the lab tells him to measure out the mass of Iron he had calculated in the pre-lab. The calculation had only called for 2 significant figures in the…

The FT-Raman and FT-IR spectroscopic analysis of 2'-nitroacetophenone (2NAP) were performed. The vibrational spectra of 2NAP was found by applying the Density Functional Theory Calculations based on Beck3-lee-yang-parr (B3LYP) level with the use of the standard 6-31G*/6-311+G** basis set. The vibrational wave number for the optimized geometry was calculated at the same level of theory. The computed values of frequencies are scaled using an appropriate scale factor to give up the excellent unity…

READING The Basic Reading Skills composite measures EE107’s ability to read a list of words and correctly pronounce nonsense words. EE107’s standard score of 75 falls in the low range at the 5th percentile, indicating that she performed at or 5 percent of her peers. Based on EE107’s performance on this composite, it appears that she will benefit from explicit instruction on word recognition skills and phonics skills. Reading Fluency refers to the ability to read quickly and accurately. It is…

to calculate the density and easily identify the liquids and see if they matched the guesses we had made initially. Our results do confirm our hypothesis that you could identify liquids if you have their densities. Since we had gotten all the calculations right it was very easy to match the densities to the liquids that we…

and there must be a pattern to its digits. Nevertheless, this was proven to be a false claim, as the digits of Pi have passed a multitude of statistical randomness assessments. Throughout history, pi has been utilized for a plethora of calculations, but most commonly for circular computations. Pi is a prominent in many modern math formulas, including the area of a circle (πr2), volume of a sphere (43πr2), and most famously,…

Lifestyle Change Project For the lifestyle change project, I chose to reduce my energy consumption. The primary reason for choosing this was to save money. Energy consumption was one aspect of the environment that had not paid much attention to. This change is also universal. Anyone can make a conscious effort to reduce his or her electricity consumption. It essentially requires awareness to the issue. Electricity use has “environmental implications, a reduction in electricity use by any means…

is a perfectly inelastic because this collision is defined as when two objects “ stick together after the collision, meaning it follows in the same direction (Perfectly Inelastic Collisions). Other than the speeds and velocities and all of the calculations of this crash there are other aspects we need to take a look at. The question is brought up should you stop at yellow lights? According to the Highway Traffic Act, when approaching an amber light you need to stop, provided it’s safe to do so…
