20‚ 2013 Lab Report 1. Problem: To find the density of a Hershey chocolate bar. 2. Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. 3: Materials: 1 whole Hershey chocolate bar‚ ruler‚ triple balance beam‚ tray‚ calculator. 4. Procedure: First‚ find the mass‚ volume‚ and density of an entire Hershey Bar. Then‚ systematically‚ break off one section at a time to calculate the mass‚ volume‚ and density for 3/4‚ 1/2‚ and 1/4 of the candy bar‚

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Microbiology-2460 Lab-003 March 31‚2008 Lab Report-Escherichia coli Abstract The purpose for this lab report was to identify and inform of an unknown bacteria that has been causing a patient to have lower abdominal and pelvic pain. To obtain the identification of this unknown bacterium‚ several biochemical tests needed to be performed in order to prescribe the correct medication to treat and cure the symptoms. Introduction In a lab today‚ I am to identify an unknown bacterium that is

then recorded the new volume and subtracted the two recordings equaling the volume of the unknown. 4. We then calculate the density by dividing the mass by the volume. 5. We then remove the metal cylinder‚ dry it and repeat to get the other two densities. Then record the measurements and density for each trial and then average the densities. Part 2: Calibration of a Buret 1. Get 4 small beakers‚ clean and dry them‚ then record the mass of each. 2. Get & Fill the buret past

Johnny Lucio Is 4680 Lab # 4 1. What is a PHP Remote File Include (RFI) attack‚ and why are these prevalent in Today’s Internet world? RFI stands for Remote File Inclusion that allows the attacker to upload a custom Coded/malicious file on a website or server using a script. This vulnerability Exploits the poor validation checks in websites and can eventually lead to code Execution on server or code execution on website (XSS attack using JavaScript). RFI is a common vulnerability and all website

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules
