McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel

Example lab report of Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Posted by Nurul Yunaliyana Experiment 5: Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Purpose: to synthesis potassium tris (oxalato) ferrate (III) trihydrate ‚K3 [Fe (C2O4)3].3H2O. Introduction: Ferrous ammonium sulfate‚ Fe(NH4)2(SO4)2.6H2O is dissolved in a slightly acid solution‚ excess oxalic acid‚ H2C2O4‚ is added and the following reaction takes place: Fe(NH4)2(SO4)2.6H2O + H2C3O4

One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

These kinds of feedback is significantly different from those we receive when touching and typing on a keyboard. Learning by doing Together with neurophysiologist Jean-Luc Velay at the University of Marseille‚ Anne Mangen has written an article published in the Advances in Haptics periodical. They have examined research which goes a long way

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential

Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s

This lab was done to learn about blood on a micro and macroscopic level. There are safety concerns when using bodily fluids. Gloves were needed and caution with the use of the lancet was important‚ which included keeping it sterile. Activity 1: Observing Your Own Blood Observations: Sketch and describe what you
