You are given an impure sample of a phenol and asked to purify it. You ask for information about the suspected impurities, but it seems no one really knows.
How many molecules of acetylene (HCCH) react with 149 molecules of oxygen to produce carbon dioxide and water?
If strong oxidizer spill occurs in the vicinity of barrels of flammable chemicals, with one of the barrels of flammable chemicals possible leaking as well, should water be used on the incident or how should mitigation proceed?
Determine the ph ( to 1 decimal place) of a slution prepered by adding 125ml of 0.759M acetic acid to 10.3g of sodium acetate. the pKa of acetic asid is in table 10.2. Assume the volume of the solution does not change?
