You carefully weigh out 17.00g of CaCo3 powder and add it to 68.85g of HCl solution. You notice bubbles as a reaction takes place. You then weigh the resulting solution and find that it has a mass of 78.88g . The relevant equation is
CaCo3(s)+ 2HCl(aq)---> H2O(l)+ CO2(g)+CaCl2(aq)

Assuming no other reactions take place, what mass of CO2 was produced in this reaction?

  • Chemistry 1 - ,

    Is mass conserved?
    mass reactants = mass products-CO2

  • Chemistry 1 - ,

    15
