The chemical equation ZnCO3 + HNO3 -> Zn(NO3)2 + CO2 + H2O

  1. Detailed information about the equation ZnCO3 + HNO3 -> Zn(NO3)2 + CO2 + H2O
    • The above equation represents a chemical reaction between ZnCO3 (Zinc carbonate) and HNO3 (nitric acid), producing Zn(NO3)2 (Zinc nitrate), CO2 (Carbon dioxide) and H2O (water).
  2. Reaction conditions
    • This reaction occurs under room temperature and standard pressure conditions.
  3. Reaction process
    • ZnCO3, upon contact with HNO3, will decompose to produce Zn(NO3)2, CO2, and H2O. This is an exchange reaction between a salt and an acid.
  4. Observed phenomena
    • When ZnCO3 reacts with HNO3, we observe a decrease in the mass of the solid ZnCO3, meaning that the ZnCO3 is being consumed. Simultaneously, the gaseous CO2 product will form bubbles that escape to the outside.
    • If the reaction takes place in a closed environment, we will see an increase in pressure within the system due to the production of CO2 gas.
