Decomposition of caco3
Thermal decomposition; CaCO3(s) → CaO (s) + CO2(g) Why is steam evolved when drops of water are added? Write an equation for the reaction occurring. The reaction is highly exothermic and the small amount of water added is partly converted to steam in the process: CaO (s) + H2O (l) → Ca (OH)2(s) Why does … See more Keep an eye on less mature students who might be tempted to suck rather than blow through the filtrate.
