  • The Effect of Sodium Carbonate on Hard Water

    3102 Words  | 7 Pages

    The Effect of Sodium Carbonate on Hard Water Aim === In this experiment, we aim to investigate the effect of sodium carbonate on hard water. Method ====== Firstly, 25.00cm3 of a sample of water was pipetted into a clean conical flask. The pipette was used because this measures and delivers a very accurate amount of liquid (to the nearest hundredth of a cm3, or 0.01cm3), but care had to taken to make sure it was not held by the bulge, as this could have made the amount inaccurate

    596 Words  | 2 Pages

    5.1 What is Molten Carbonate Fuel Cell (MCFC) ? It a cell that takes Hydrogen, Oxygen and carbon dioxide as feed and produces water. It operates at extremely high temperature (between 6000C – 7000C). Molten Carbonate fuel cells are usually %45 to %55 efficient.

  • Producing Carbon Dioxide from a Metal Carbonate

    1137 Words  | 3 Pages

    Producing Carbon Dioxide from a Metal Carbonate Metal Carbonate Metal Oxide + Carbon Dioxide Thermal decomposition ‘is when a substance breaks down into simpler substances when heated, often with the help of a catalyst. It’s different from a reaction because there’s only one substance to start with’. I came across this information in the EDEXCEL Modular Science revision guidebook 1. Thermal decomposition is the breakdown of a substance using thermal energy, this is not a reaction.
