Respond to 6 questions . You must show your work for any questions requiring calculations or explanations.

1.What is the common name of CaCO3, calcium carbonate. Describe how it can be used in a real-life situation,

2.What happened to the excess reactant after the reaction was complete?

3.What is the limiting reagent? Show your calculations

4. What is the theoretical yield of CaCO3 in grams? Show your calculations.

5.What is the experimental yield of CaCO3?

6. Use the following equation to find the percent yield of CaCO3 ; experimental yield of product / Theoretical yield of product


initially, I precipitate calcium carbonate (CaCO3) from the reaction between sodium carbonate (Na2CO3) andcalcium chloride (CaCl2) and obtain this results:
