Ethyl alcohol and isopropyl alcohol are the most commonly used agents.

Explanation:

Isopropyl alcohol is used in a 10% concentration.

- not true, to be useful as a chemical control agent its is the most potent with a (water) solution containing 70% isopropyl alcohol.

Ethyl alcohol and isopropyl alcohol are the most commonly used agents.

-true

Dipping small instruments in ethyl alcohol for a few seconds will result in disinfection.

- ethyl alcohol is denaturing proteins, inhibiting metabolic processes so it has bactericidal and fungicidal properties. However the proces is not so fast so the instruments are not disinfected in few seconds.

Alcohols will eliminate bacterial spores.

-alcohols are not sporicidal, however they do inhibit the processes of sporulation and germination but they do not eliminate the spores.
