When limestone (which is principally CaCO3)
is heated, carbon dioxide and quicklime
(Cao) are produced by the reaction
CaCO3(s) 4CaO(s) + CO2(g).
If 12.5 g of CO2 was produced from the ther-
mal decomposition of 40.79 g of CaCO3, what
is the percentage yield of the reaction?
Answer in units of %.

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
