Title: Observation of Macroscopic Chemical Changes‚ Alice Kimbrell‚ Chemistry 101-DS01:74589‚ 5/31/2013. Purpose: In this lab‚ I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change‚ and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Module 8 Writing Assignment 1). What is the proper care for heart attack victims? There are four steps in caring for a heart attack. The first step is to immediately call 9-1-1‚ if a heart attack is suspected or if the victim’s chest pain does not so away in a victim taking nitroglycerin. However‚ medications to dissolve a clot must be given early. Also‚ do not drive yourself or anyone else to the hospital. The second step is to monitor the victims breathing. If he/she becomes unresponsive and stops

this lab was to a digital oscilloscope to measure various signals. The goal of Part 1 was to measure the mean value‚ the frequency‚ peak to peak voltage‚ and the RMS voltage of a triangular input signal. To meet this goal‚ a function generator was used to generate a 1 kHz triangular wave signal with a 1 V amplitude‚ and the oscilloscope was used to measure the values of that signal. Using the oscilloscope‚ the mean value was found to be -37.6 mV‚ the RMS Voltage was 292 mV‚ the frequency was 1 kHz
