If you react 5.6 moles of pbs (s) in the air, how much o2 (in grams) would be needed for a complete reaction?

What is the difference between a strong acid and a weak acid? A strong acid has a higher pH than a weak acid. A strong acid is 100% ionized; a weak acid is less than 100% ionized. A strong acid is diprotic or triprotic; a weak acid is monoprotic.
