Part C. You carefully weigh out 16.00 g of CaCO3 powder and add it to 64.80 g 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 74.24 g. 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?
Express your answer to three significant figures and include the appropriate units.
When a chemical reaction occurs, atoms rearrange to form new compounds, but no new atoms are created nor are any destroyed. This concept is called conservation of mass. Mass conservation can be seen in a balanced chemical equation, where the numbers of each kind of atom are the same on both sides of the reaction arrow.
