Final answer:
The strong acids from the given options are HCl, H2SO4, and HNO3; these acids fully dissociate in water. CH3COOH is a weak acid and does not dissociate completely.
Step-by-step explanation:
The strong acids from the list provided are:
- HCl (hydrochloric acid)
- H2SO4 (sulfuric acid)
- HNO3 (nitric acid)
These acids are known to dissociate completely in water, which means that their proton donation process is nearly 100% complete, indicating their strength as acids. On the other hand, CH3COOH (acetic acid) is not a strong acid; it is considered a weak acid because it does not completely dissociate in water.
