Question

Write a word equation for the reaction below: copper carbonate yields copper oxide and carbon dioxide.

Answer 1

Respuesta:

Balanced equation for the decomposition of calcium carbonate:  

    CaCO3 → CaO + CO2  

3 moles of carbon dioxide CO2 are produced.  

The amount of moles of carbon dioxide produced from 3 moles of calcium carbonate is calculated using a conversion factor based on the chemical equation for the decomposition of carbonate as follows:

   

  3 mol CaCO3  

    moles CO2 =?  

   CaCO3 → CaO + CO2 balanced decomposition equation:

 

  1 mol 1 mol 1 mol    

   3 mol CaCO3 * 1 mol CO2 / 1 mol CaCO3 = 3 mol CO2.
