Drain cleaner has a ph of about 14. how can it be classified, based on its ph? a. it is a very strong base. b. it is close to neutral but slightly basic. c. it is close to neutral but slightly acidic. d. it is a very strong acid.

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
