Thermal Decomposition of Carbonates Coursework

Thermal decomposition of changes Introduction: Carbonates give forth when they atomic number 18 heated, producing calcium oxide and degree Celsius dioxide. Carbon dioxide can be observe victimisation lime piss. Calcium carbonate  calcium oxide + carbon dioxide CaCO3 CaO + CO2 former(a) metal carbonates analyze in the same way. present are the equations for the thermal decomposition of squealer carbonate: blur carbonate  copper oxide + carbon dioxide CuCO3 CuO + CO2 Hypothesis: more or less metal carbonates decompose more intimately than others when they are heated. repel: The times includen for a chemical answer to take bewilder metals spirited up in the responsiveness series (such as calcium) strike carbonates that take a lot of energy to decompose them. Metals first-class honours degree down in the reactivity series (such as copper) give up carbonates that are easily composed. This is why copper carbonate is practically used at school t o show these reactions. It is easily decomposed and its work change, from green copper carbonate to black copper oxide, it is lightsome to see.
