Tums is a popular remedy for acid indigestion. A typical Tums tablet contains calcium carbonate plus some inert substances. When ingested, it reacts with the gastric juice (hydrochloric acid) in the stomach to give off carbon dioxide gas. When a 1.328-g tablet reacted with 40.00 mL of hydrochloric acid (density: 1.140 g/mL), carbon dioxide gas was given off and the resulting solution weighed 46.699 g. Calculate the number of liters of carbon dioxide gas released if its density is 1.81 g/L.

Please predict the products for each of the
following reactions.
Clearly show the regiochemistry (Markovnikov
vs anti-Markovnikov) and stereochemistry
(syn- vs anti- or both).
If a mixture of enantiomers is formed, please
draw all the enantiomers.
Hint: In this case you must choose the best
answer to demonstrate the stereochemistry of
H2 addition.
