Observations and Chemical Changes By: Andre the Giant Higgson 02/19/14 CHE 107 E1 Intro to Chemistry 1 Objective Certain Chemicals like Bromthymol blue and Phenolphthalein can be added to other chemicals to determine acidity or basicity. Other reactions can be observed as well when different chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your

Observations of Chemical Changes Purpose/Hypothesis: To observe how acids react with bases and examine reactions of common household cleaners and the macroscopic changes these chemicals undergo. I expect for each solution to react differently when mixed with acids and bases. Procedure: I have a well-plate-96‚ a piece of white and black paper‚ and the chemicals from the Observation of Chemical Changes Experiment Bag. I used a different well for each combination of solutions. I placed two

DESCRIPTION The Centripetal Acceleration lab consists of using a pendulum bob swinging continuously. This will help see the F_max(tension) and F_(mean )(weight of the pendulum)‚ net force (N) and v_mean(velocity). RESULTS When starting the lab the first thing to do is to measure the cylinder properties (the bob) in table one. The measurements were: diameter (D) is .0815m‚ height (H) is .025 m‚ mass is .06591 kg‚ and the 〖Weight〗_theory W is .645918 Mg‚N. Second thing to do is to launch from

For the rest of us‚ they are less apparent but we still probably use them to predict how changing one factor in our lives may affect another--without even realizing it. Polynomials in Gravitational Acceleration Polynomials also are used in scientific problems‚ including gravitational acceleration problems. The polynomial equation needs to include the object’s
