Separation of a Mixture Introduction: Mixtures are not unique to chemistry; you use and consume them on a daily basis. The beverages you drink each morning‚ the fuel you use in your automobile‚ and the ground you walk on are mixtures. Very few materials that you encounter are pure. Any material made up of two or more substances that are not chemically combined is a mixture. The isolation of pure components of a mixture requires the separation of one component from another.

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any

Aim • To calculate the SHC of water • To see how accurately I can measure a known quantity Research Question • Will the experiment carried out give us a good approximation of the SHC of water? Hypothesis • The result we will get as the SHC of water will not be exactly the same as the literature value‚ but will be a very close figure to the literature value of the SHC of water as there will be some limitations to our experiment. Variables Independent: temperature of water Dependent:
