Equation for the reaction which took place: Hydrochloric acid + calcium carbonate -> calcium chloride + carbon dioxide + water
When the reaction stopped the total mass had decreased from 102.5g to 101.4g.
some water had evaporated from the beaker what else caused the drop is mass?

  • Science -

    Some of the CO2 was lost as a gas.

    Also, depending on how hot the mixture became, maybe some of the water was lost as steam.
