The speed of chemical reactions – class experiment By Julia Shuker Year 10 science – Miss Phillips – Term 2 – 2013 – Julia Shuker Aim The aim of the experiment was to investigate the factors that increased or decreased the speed of chemical reactions between two different chemical reactions. Hypothesis If certain factors‚ such as concentration‚ temperature‚ catalyst and surface area are increased then the reaction rate will also increase due to the particles

and Results Did you observer any chemical changes in this experiment? Yes. CuCo2 turned green when I applied heat to it. B. What evidence did you use to decide that something was a chemical change? I viewed my other test tubes to see if it there was a chemical change in those. C. Give at least two examples of chemical changes you observed. Zn and MgO when I Diluted HCL D. Classify the following properties of sodium metal as physical or chemical: • Silver metallic color: Physical

Wherever explosion or fire hazards exist‚ proper plant layout and adequate spacing between hazards are essential to loss prevention and control. Layout relates to the relative position of equipment or units
