the brake caliper. For this you have to take out the bolts or slide pins‚ depending on what type of brake calipers your car has. While doing this you have to be careful not to drop the caliper‚ if you do you can break the brake hose and force yourself to do a lot more work. Once it is off you should use safety wire to hang the caliper on the coil spring to prevent stressing the brake hose that is connected the caliper. The next step is to collapse the piston that is in the caliper. First part

Enzymes are globular proteins‚ responsible for most of the chemical activities of living organisms. They act as catalysts‚ substances that speed up chemical reactions without

Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

SCIENCE PROCESS SKILLS Basic Science Process Skills: 1. Observing - using your senses to gather information about an object or event. It is description of what was actually perceived. This information is considered qualitative data. 2. Measuring - using standard measures or estimations to describe specific dimensions of an object or event. This information is considered quantitative data. 3. Inferring - formulating assumptions or possible explanations based upon observations. 4

Computer The Determination of a Chemical Formula 1 Second‚ you will conduct a chemical reaction with the dried sample‚ which will produce elemental copper. By measuring the mass of copper that forms‚ you will have the necessary information to determine the moles of copper and chlorine in your sample‚ and you will be able to establish the proper chemical formula. OBJECTIVES • • • In this experiment‚ you will Ev al Determine the water of hydration in a copper chloride hydrate

of this study is the ability to tell of two points verses than one that pressing on the skin depends on two things: the concentration of the sensory receptors and the connections that the sensory nerve cells make in the brain. An esthesiometer or caliper; compass-type instrument was used to determine limits of two-point discrimination sensitivity in several skin areas on the subject’s forearm‚ thumb and index finger. The activities involve the touch sense of the skin‚ which allows us to distinguish

Instructions: 1. Start by placing the jack underneath the car in the jack slot to ensure it doesn’t slip‚ then raise the vehicle. 2. Use the lug wrench to take the wheel off. 3. Un-screw the two bolts to the brake caliper which sits on top of the rotor. 4. Once

The LabQuest and the Vernier pH sensor was then hooked up and turned on to measure and graph the pH of the solution and the volume of NaOH. The Vernier pH sensor was then was placed in the solution and remained in the solution throughout the duration of the experiment. Then‚ the rate of the drip from the buret was then turned on to have
