I need help with these two chemistry problems! Calculate the [OH-], pOH and pH of these solutions:
a) 0.50 mol/L KCN b) 0.20 mol/L NaClO

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?

Calculate the number of moles of ethane in 100 grams

3) in peaches, [oh]=3.16x10-11 m a) find [h+ ] b) what is the ph? c) is the solution acidic, basic, or neutral?
