When cl2 gas is added to water during the disinfection of drinking water, it hydrolyzes with the water to form hocl. the disinfection power of the acid hocl is 88 times better than its conjugate base, ocl-. the pka for hocl is 7.5. (a) what % of the total disinfection power (i. e., hocl + ocl-) exists in the acid form at a ph = 6? (b) at ph = 7? (by "percentage of disinfection power" mz means  expressed as a percent.) 97% and 76%

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
