What is the pH of a solution prepared by titration 100.0 mL of 0.100 M Acetic Acid (CH3COOH) with 20.0 mL of 0.250 M NaOH?
The pH of the solution at the equivalence point. e) The pH of the solution after 40.0 mL of HCl are added.
In covalent bond formation, electron sharing occurs between elements with relatively low EA and low IE. Please explain the answer as well.
Explain (using chemical equations) why NaOCl (bleach) is not terribly effective at killing bacteria in pools or tubs where the water has become acidic over time.
How many grams of NaN3 are required to produce 11.0 ft3 of nitrogen gas if the gas has a density of 1.25 g/L?
