chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of exposure and is also a lung irritant. To avoid harm and ensure safety‚ eye

Comparisons of Research Design There are several research design methods that have been developed for the field of psychology. Instead of arguing over which is the best method‚ it is more appropriate to compare two of the favored designs. Each one has positive attributes along with negative factors that may influence results. It is more important to understand and decipher which is the most appropriate method to utilize based upon the

Identify that ethylene‚ because of the high reactivity of its double bond‚ is readily transformed into many useful products Ethylene‚ because of the high reactivity of its double bond‚ can form many useful products‚ such as plastics (polyethylene). For example‚ ethene can react with water to form ethanol‚ with a H3PO4 catalyst at 300oC. Ethene can react

Electrolysis a) Electrolysis is the decomposition of a substance to give simpler substances. The substance being electrolysed has to be an ionic compound. b) The substance being decomposed is called the electrolyte. c) In electrolysis the electric current enters and leaves the electrolyte by conducting rods called electrodes. The positive electrode is called the anode and the negative electrode is called the cathode. d) For electrolysis to occur the electrolyte must be in liquid form so that
