In the 1980s, there was an international agreement to destroy all stockpiles of mustard gas, ClCH2CH2SCH2CH2Cl. When this substance contacts the moisture in eyes, nasal passages, and skin, the ?OH groups of water replace the Cl atoms and create high local concentrations of hydrochloric acid, which cause severe blistering and tissue destruction. Complete and balance the equation for this reaction, and calculate ?H°rxn.
What is the molarity of a solution prepared by dissolving 10.5 grams of NaF in enough water to produce 750 mL of solution?
Alkynes can be hydrated in the presence of acid and HgSO4, by electrophilic addition of a molecule of water to the triple bond. The reaction proceeds by way of a carbocation intermediate
