Abstract In this experiment‚ the absorbance of KMnO4 was measured by spectrophotometric method to determine the molar concentration and the molar extinction coefficient of KMnO4. In part 1‚ in order to determine the maximum absorbance wavelength of KMnO4‚ we measured the absorbance of the sample solution which contains KMnO4 at the wavelengths between 330nm and 660nm‚ and plotted the λ and A points; the λmax was 530nm. In part 2‚ the effect of concentration on the absorbance was examined. We prepared

Jahzeel Morales Jessa Arellano September 19‚ 2014 Period 4 Lab #1: Density Determinations for Solutions Theory: The density of a sample of matter is very useful when trying to find the identity of an unknown substance. The units of density are quoted in (g/mL) for liquid samples of matter. For that reason if the volume is known of a liquid‚ determining its density is easily determined by weighing it accurately. Density can also be used as a tool for finding the concentration of solutions

Determination In “The Glass Castle” we see many different possibilities pertaining to Maslow’s Hierarchy of Needs. We see the father‚ Rex and one of the daughters‚ Maureen‚ who fall victim to Maslow. Then there’s Jeanette and the mother‚ Rose Mary who have both seemed to achieve self-actualization regardless of their hardships. Traditionally‚ Maslow’s Hierarchy is thought to be achieved by working up from the bottom of the pyramid to get to the top. However‚ in “The Glass Castle” this is not particularly

This section will explore the concept of the iron triangle and related terms such as pork barrel politics. This thesis will look into the debates surrounding the concept of the iron triangle in the next chapter. In this section it will be explored what the nature of the iron triangle is‚ how it came into being and what kind of effect it had on Japanese society. The iron triangle First‚ we need to establish what the concept of the iron triangle entails. Japan rebuilt its economy after the Second

The process by which some metals when exposed to atmospheric condition i.e.‚ moist air‚ carbon dioxide form undesirable compounds on the surface is known as corrosion‚ The compounds formed are usually oxides . Rusting is also a type of corrosion but the term is restricted to iron or products made from it .Iron is easily prone to rusting

SoCal Study Group Beach Bods Theme 4 Step 1 – Identify the BOTTLE NECK – in this case‚ the 2nd reactor (Fluidized Bed) was the bottleneck at the 4th step of the 7step process. The 2nd reactor is limited to 400 tons per cycle and each cycle takes 4 hours to complete. Since this is a continuous process system‚ it is important to ensure the 2nd reactor is always full as it has limited capacity. From there‚ we worked backwards through the previous three steps to arrive at the initial tons
