Economic Indicators Essay

In the experiment I observed that distilled water has a pH of 7 when I used the universal indicator paper as shown in Fig.8 which turned to a light shade of green which was similar to that of the substances with a pH of 7. The reaction started off at a slow rate but as time went on the rate of reaction began to increase to such an extent that the

Robert M. Carton Principles of Accident Causation March 12, 2017 APT #10  1. How do airspeed indicators and altimeters work? Both airspeed indicators and altimeters are relatively similar to one another. The airspeed indicator utilizes and receives data from the pitot tube and the static port on an aircraft. In short the air pressure is collected by the pitot tube is compared to the static air pressure to give the pilot an accurate indication of how fast the aircraft is moving. The pitot

Results This lab compared two different streams against each other from a biological, physical and chemical bases. From this lab we are able to see the differences and similarities as well as the differences between each streams. For the Tippecanoe river there was a total of 20 organisms, 7 from the upstream transect and 13 from the downstream transect. This differed from Cherry creek have a total of 209 organism. This total was split a 110 down from upstream and 99 from the down stream transect

CHAPTER: 1 INTRODUCTION 1.1 Introduction Garcinia Mangostana is a fruit commonly known as Mangosteen. The fruit belongs to Guttiferae family and the tree is 6-25 m of height with dense and heavy branches [1]. It is commonly cultivated in Southeast Asian countries like Malaysia, Indonesia and southern states of India. In India, it is grown in tropical humid evergreen rain forests of the Western Ghats. The colour of the fruit varies from dark purple to red in colour. The edible part of the fruit is

The research question for the Alka Seltzer Lab is, “What is the effect of different surface areas of an Alka Seltzer tablets reaction time?’. Inside of an Alka Seltzer tablet there are two key ingredients; which are citric acid and baking soda. When a tablet is dropped into a liquid, the acid and baking soda show a physical reaction of fizzing and eventually dissolving. Materials needed for this lab was goggles, aprons, beakers, water of the same temperature, mortar pestle, and three alka seltzer

In this experiment we will be titrating the titrant sodium hydroxide against the analyte, which is the substance being analyzed, hydrochloric acid. Titration is the process of analyzing base and acid added together. The objective is to calculate the unknown concentration of hydrochloric acid with the standardized solution of solid sodium hydroxide. The standardized solution is the known concentration but since sodium hydroxide naturally reacts with air, we must first determine the true concentration

concentration of another solution. An analyte is the concentration of an unknown solution . A titrant is the concentration of a known solution. The glassware needed to perform a titration are a buret, a flask, and an indicator of pH meter. The buret sends the second reactant to the flask. An indicator detects the endpoint of this reaction. Standardization is the process in which you determine the concentration of the titrant before performing the titration. One would need to make a standard solution to be

Overall, the experimental results were similar to the results needed to identify the cobalt ammine halide coordination complex. The color of the compound was dark purple and it looked just as expected as the experiments leading up to the collection of the synthesized cobalt compound had little to no errors. The percent yield of the compound was not 100% due to small errors throughout experiments such as losing some of the compound during transferring, more liquid evaporating than desired, and not

The content of these tubes was then later transferred to separate small labeled beakers. The initial pH of the water in test tube A was then measured and recorded using a pH meter. Next. One drop and 1 mL of 0.1 M HCl was added to the water in test tube A, and the pH was measured and recorded. The pH meter was rinsed off each time it was used with distilled water and blotted dry. The initial pH of test tube B was then measured and recorded. Using a graduated cylinder and a pipette, 1 mL of 0.1 M

The genus Proteus contains four species P. mirabilis, P. vul¬garis, P. myxofaciens and P. penneri (Kumar 2012).One of the distinguishing characteristics of this genus that separates it from other members is their capacity of synthesizing Phenylalanine deaminase. No other members contains an enzyme Phenylalanine deaminase that removes an amino group from Phenylalanine. Moreover, all four members of Proteus genus is responsible for urinary tract infections and are contracted in long-term-care facilities
