Lab #1 1. List the five (5) steps of the Hacking process. Reconnaissance‚ Scanning‚ Gaining Access‚ Maintaining Access‚ Covering Tracks 2. In order to exploit or attack the targeted systems‚ what can you do as an initial first step to collect as much information as possible about the targets prior to devising an attack and penetration test plan? The first step would be the reconnaissance or footprinting step of the hacking process. 3. What applications and tools can be used to perform

On the Intro screen‚ mess with the apparatus‚ changing the blocks‚ observing what happens when the mass‚ volume and densities are held constant. 2. Check and uncheck the boxes under “Show Forces” to see where they act. Intro: Give a brief description

Discussion and Conclusion In this lab‚ a submarine Adventure: Density Saves The Day‚; I had made many of the calculation for the best result of the lab. My calculations section contains: the volume of the unknown metals‚ where I figure out the volume of each metal so that I will be able to determine its density in order to find its identity; the density of unknown metals‚ where I figure out the density of each metal so that I will be able to determine its identity; percent error between known

The study of urinary chemistry on stone forming minerals will provide a good indication of risk of stone formation. Urinary supersaturation with respect to stone-forming constituents is generally considered to be one of the causative factors in calculogenesis. Though supersaturation of stone forming salts in urine is essential‚ abundance of these salts by itself will not always result in stone formation. Various substances in the body have an effect on one or more of the stone forming processes (nucleation

(Ba(OH)2). Through the conductivity‚ the equivalence point can be determined; from there‚ the concentration of the Ba(OH)2 solution can be found. The final product of the reaction between sulfuric acid and barium hydroxide is insoluble. According to the lab manual‚ during the reaction‚ the total number of dissociated ions in solution is greatly reduced as a precipitate is formed. With the Conductivity Probe‚ the changes in conductivity of the solution will be analyzed. The collection of Ba(OH)2 precipitate

Although I love science‚ I encountered more problems in this subject than any other. Recently‚ I was assigned a lab. The purpose was to let Copper Sulfate react with Aluminum and obtain Copper. Before the experiment‚ I set up the stoichiometric equation carefully‚ predicting the production of Copper using my assigned mass of Copper Sulfate. Additionally‚ I intentionally made Copper Sulfate an excess in my equation‚ since it would be dissolved in water and I would only have to collect Copper at the
