Calcium carbonate reacts with hydrochloric acid (hcl) to produce calcium chloride, water and carbon dioxide. you need to have 267 grams of carbon dioxide for another process, so you need to start with __ mol hydrochloric acid.
__ caco3 + __ hcl → __ cacl2 + __ h2o + __ co2

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.

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.
