Thermal Decomposition of Carbonates Coursework

Thermal decomposition of changes Introduction: Carbonates give forth when they argon heated, producing calcium oxide and blow dioxide. Carbon dioxide can be notice victimisation lime pee. Calcium carbonate  calcium oxide + carbon dioxide CaCO3 CaO + CO2 former(a) metal carbonates recess in the same way. hither are the equations for the thermal decomposition of blur carbonate: bruiser carbonate  copper oxide + carbon dioxide CuCO3 CuO + CO2 Hypothesis: slightly metal carbonates decompose more soft than others when they are heated. learn: The times includen for a chemical reply to take speckle 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 to show these reactions. It is easily deco mposed and its work change, from green copper carbonate to black copper oxide, it is lightsome to see.
