group resulting in the formation of a double bond between two carbons. For the experiment we used 2-Methylcyclohexanol as a beginning reagent to dehydrate and possibly form 3-methylcyclohexene‚ 1-methylcyclohexene‚ or methylenecyclohexane. Drierite® (Calcium Sulfate) was used as a drying agent to help break the alcohol and hydrogen groups from the carbons. Concentrated phosphoric acid was used as a catalyst to help move the reaction towards the products motioned above. To determine the successfulness

Salt and chalk were rubbed across teeth. The Chinese chewed on twigs to freshen their breath. Nevertheless‚ chemicals like fluoride‚ xylitol‚ calcium carbonate‚ and chlorhexidine are proven to work stronger in the act of protecting teeth. This experiment will look at whether the eggshells (which acts as teeth) are more damaged by the natural solutions or chemical solutions‚ and which one of the solutions

The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding

LOG ON TO SKILLSOFT TO DOWNLOAD THE LAB INSTRUCTIONS AND START THE LAB. In computers binary code is the language that communicated between applications. Binary Code is a coding system using only digits 0 and 1 to represent a letter‚ digit or other characters in a computer. It is hard to imagine that huge and hard calculations are done on computers applications

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

Title: The Mass of Quartz Purpose: To determine the density slope for water and alcohol and apply the understanding to determine the volume of a quartz sample without measuring the volume or calculating it. Hypothesis: The hypothesis of this lab was by using the density of alcohol we could calculate the density of a quartz samples. Controls and Variables: Independent variable: Volume of water and alcohol Dependent variable: The weight of the liquid or solid Controls: The volume of

October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden
