Lalin Candium Lab Report Chemistry Block H Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes Objective: In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment‚ it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due

For one‚ when sample size was n=3‚ there was a marked decrease heart rate for samples treated with nicotine from a basal heart rate of 147.04 bpm to a drug treated heart rate of 66.67 bpm which is contradictory to the literature and contradictory to experimental values when n=12. Nicotine is a known

Preliminary Unknown Report Alexis Grettenberger 800503431 Katie Young Alexis Grettenberger Biol 311 Lab 11/21/14 Preliminary Unknown Report Purpose: The purpose of this experiment was to identify a specific unknown bacterium that was isolated from a multitude of bacteria in a sample of contaminated dirt by running it through a series of identification techniques. Some of these techniques were simple staining‚ gram staining‚ and isolation techniques. The hypothesis of this experiment was that

Officer were dispatched to 399 West Arlington Street where dispatchers relayed a message from the above caller who reported a subject armed with a gun. County dispatched the call in a very confusing manner. They initially said the caller was at 399 W Arlington St and the armed subject was outside of the said address making it seem that the caller was inside the address supplied which was later found to not be accurate. While arriving on scene dispatch advised officers that the armed subject was walking

mathematical tool used in analytical chemistry that provides a set of reference points that unknown chemical substances can be compared to. When analyzing certain substances‚ scientists are often unable to get a completely accurate understanding of the substance’s makeup. With a calibration curve‚ chemists can compare known information about unknown substances to make estimates about its makeup and chemical properties. Aim:- To use the colorimeter in proper way and observe the absorbance through the

couple of key things about lab safety and procedure during this experiment. While working with the hot plates‚ I learned to pay a lot of attention to whether or not the hot plate was plugged in or turned on‚ as well as whether or not the wax was getting too hot. Measuring each substance into the cup was an important experience because it taught me to be deliberate and careful when measuring so as to not waste materials‚ making sure we did not have to start over. While this lab is a good starting point

Equilibrium Paper By: Brandon Walker ECO/561 July 14‚ 2014 Instructor: Mark Erenburg This paper was written to describe a real world experience in a free market were change occurred in supply or demand as a result of world events that led to the need for a move between two equilibrium states. I will also explain the process of how that movement occurred using behavior of consumers and suppliers while using graphs as indicated. Real Word Experience According to a United
