speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is the least reactive metal so its an unstable carbonate and the bonds are much weaker. So the metal that is

Socrates proposes a “myth of the metals” the ideal city’s citizens must acknowledge. These citizens accept their respective positions so as to maintain the social and political order‚ or‚ as Socrates articulates‚ to prevent revolution (422a). The “myth of the metals”‚ or the “noble lie”‚ emphasizes the importance of each individual fulfilling a specific function‚ which allows them to practice what Socrates and his peers have defined as justice (346d). Socrates propositions this “necessary falsehood”

Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

Among the most harmful and dangerous non-metal compunds are nitrogen oxides‚ sulphur dioxide‚ carbon dioxide‚ carbon monoxide‚ and hydrogen sulphide. These can cause devastating effects to human beings‚ plants‚ animals and the environment. Matals are generaly less harmful‚ although lead is extremely toxic. Hydrogen sulphide is a highly toxic gas. It has a very bad smell‚ often identified in rotten eggs and stink bombs. Hydrogen sulphide interferes with cellular respiration. If inhaled‚ Hydrogen
