Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry

Ohm’s Law Lab Report Number Three Quyama T. Wheeler @02669651 Partner: Munah Kaye Amber Frazier Objective: To demonstrate Ohm’s law and to determine the resistance of a given resistor. Theory: Ohm’s law is the assertion that the current through a device is always directly proportional to the potential difference applied to the device. Electric current is the moving of charges from a higher potential to a lower potential. Wires of different material (a copper wire versus a silver wire‚ for

Helicopter Lab * Objectives: the objective is to study the effect of variables on the helicopters’ flight. The goal is to observe which can stay in the air for the most time. * List of materials: 3 patterns for a paper helicopter‚ scissors‚ tape ruler‚ and paper clip. * Procedures: 1. Cut the solid lines and fold the dashed ones. Fold A toward you and B from you to form wings. Then fold C and D inward to overlap‚ forming the body. Fold up the bottom on the dashed line and hold it

The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together

Kristen Sierman Lab Report: Experiment #7 Group #4 October 16th‚ 2012 Forces on a Pulley System A. Statement of the Problem The purpose of this lab was to address the following questions: how does the acceleration of a pulley system depend on the mass of the driving objects? And how does the acceleration of a pulley system depend on the mass of the driven object? To achieve this‚ a dynamic track was set up with a string attached to a cart. The string was part of a pulley system (the pulley
