Chemistry Gcse Question Thermal Decomposition Of Metal

The equation for group 2 metal carbonate thermal decomposition is. MCO3 - MO CO2 hence the metal carbonate and CO2 react in a 11 molar ratio. Therefore calculate the number of moles of the metal carbonate and then multiply it by the Mr of CO2 44 to calculate the mass of CO2 for each. Then compare to test the hypothesis.

Thermal decomposition of metal carbonates Experiment

Thermal Decomposition Of Metal Carbonates Experiment

Thermal decomposition of metal carbonates. This experiment involves a comparison between the thermal stabilities of carbonates of reactive metals, such as sodium and potassium, and the carbonates of less reactive metals, such as lead and copper. Metal carbonates decompose when heated. Some carbonates are more reactive than others.

Nov 29, 2004 Carbon-coated spherical graphite particles improve the thermal stability of the graphite anode. Carbon coating modifies the SEI film and blocks the edge planes in the graphite. Blocking of the edge planes reduces the formation of a secondary SEI film and hence reduces the heat produced due to the decomposition of the secondary SEI film.
