Explanation:
1. Hypochlorous acid (HOCl) is a weak acid that forms when chlorine dissolves in water, and is partially dissociated, forming hypochlorite. HOCl is considered a strong oxidizing agent responsible for the killing action of germs in chlorine solutions.
2. Acetic acid is also known as ethanoic acid. It has a distinctive sour taste and pungent smell, and is generally considered a weak acid. in a concentrated form, acetic acid can be corrosive.
3/4 . Methylene chloride is an organochloride compound with the formula CH2Cl2. It is a colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. It is normally stable, non-flammable and non-explosive when mixed with air at temperatures below 100 °C, but its vapor is flammable only when present in relatively high concentrations of about 14% to 22% in air. Research shows that it is very much possibly carcinogenic, and it has been linked to cancer of the lungs, liver, pancreas, breast cancer and salivary gland cancer in laboratory animals.
5. Laboratory and medical waste are not to be disposed in the trash with regular wastes, as they are potentially toxic. Special disposal methods and agencies exists to take away such wastes.

Explanation:
Percent error =[ (8.96-8.78) / 8.96]* 100
= 0.020089 * 100
= 2.0089 %
Answer:
d sub level starts from the 3rd energy level; means you can see electrons in d sub level in any energy levels after third one.
So the answer is "In any energy levels ≥ 3"
A simple information ; s sub level is in any energy level,
p sub level is in any energy level beginning from the 2nd energy level,
d sub level appears ≥ 3rd energy level
f sub level appears in 4th energy level and over.
Hope it helps!
