Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

1) Identify the three IP address classes‚ the default subnet mask used with each‚ and the number of hosts for each. The three IP address classes are class A‚ class B‚ and class C. Default subnet mask for class A = 255.0.0.0 Default subnet mask for class B = 255.255.0.0 Default subnet mask for class C = 255.255.255.0 The number of hosts that class A can have is 16‚777‚214 The number of hosts that class B can have is 65‚534 The number of hosts that class C can have is 254 2) What is the subnet

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

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

Lab Report The Effect of Resting on Clothespin Squeezing. Hypothesis: If you rest then the clothespin squeezing rate will increase. Materials:- Clothespin Clock Sneakers Procedure: Separate class into two groups (exercisers and resters). Exercisers will do jumping jacks for a minute. Exercisers and registers will squeeze clothespin for a minute Repeat steps two and three. Total of three trails. Precaution: Shoes must be tied. Space between exercisers. Healthy exercisers
