Aim: The aim of my experiment is to determine the different permeances of several metals by measuring the effects of eddy current damping of the motion of a simple pendulum. Apparatus: The experiment involved the use of the following equipment: Electromagnet Power Supply Retort Stand w/ Boss & Clamp 3 …

Aim The target of this investigation is to find out how the force you exert on pulling back a rubber band, which will in turn catapult an empty margarine tub, affect the distance which the margarine tub will travel. We will not be changing any of the other factors of …

Macromolecules are huge highly organized molecules. These molecules carry out the activities of the cell. There are four major categories in which these molecules can be placed into. These groups include carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are organic molecules that are usually used to store chemical energy and …

Aim To design an experiment to measure a volume of gas that will show which of the two equations given is more likely to be the correct volume. Experiment Equations (s) Equation 1: 2 KNO3 (s) 2 KNO2 (s) + O2 (g) Equation 2: 2 KNO3 (s) K2O (s) + …

Abstract The main objective of this experiment was to find the mole to mole ratio of is NaHCO3(s), or sodium bicarbonate, to NaCl, or sodium chloride when it is reacted with excess hydrochloric acid. The result of this was a 1 to 1 ratioThe other main objective, which was similar …

Hypothesis: If solution of compound and water has high conductivity level, compound is ionic. If compound dissolves in water quickly, it is ionic. If compound takes a long time to melt (high bp), it is ionic. If compound is crystalline, it is ionic. If solution of compound and water has …

Early in the 19th century, scientists worked with the basic principles of electrophoresis. Scientists measured the behaviour and properties of small ions moving through solutions in an electric field. In the 1930’s, Arne Tiselius developed the “Tiselius apparatus” for separating protein molecules through electrophoresis. By the 1960’s, many different gel …

Aim: * The aim behind this science is to measure colours and to predominantly quantify the colour of light sources or objects from visual colour matches. (This means that the eye(s) are used as a tool to identify if the colour is identical or not. Scenario: I am a scientist, …

The rate of reactions is how fast something changes from its reactants to its products. For a reactions to occur, the particles must strike with enough energy. At the start of the practical only some of the reactions will have enough energy to strike with each other and create energy …

In this practical examination I am provided with a ‘100-volume’ hydrogen peroxide solution. Taking the ‘100-volume’ into consideration I have to plan two experiments that would enable me to determine the exact concentration of H2O2, in mol dm-3. Titration The first experiment I shall carry out will be a redox …
