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

Carbon is denoted by the symbol C‚ is part of group 14 on the periodic table‚ and is the fourth most abundant element in the universe (by mass). Carbon has an electron configuration of 1s2‚ 2s2‚ 2p2. With 4 valance shell electrons it is expected to form 4 bonds‚ this means carbon is tetravalent. However the s orbitals do not form the same type of bond (with other atoms) as the p orbitals‚ this is because their shapes are different. For example CH4 would have the following bonds: C(s)-H(s)‚ C(s)-H(s)

Argument: Acceleration is caused by two factors‚ mass and force. The graph above shows the relationship between acceleration and force as proportional. As the force upon the car in the experiment increased‚ the acceleration of the car increased by a similar proportional. This complies with Isaac Newton’s second law of motion‚ the law of acceleration‚ which describes acceleration and force as two proportional measures in the equation F (force) = m(mass) x Ac(acceleration)‚ also described in
