Answer:
A nonelectrolyte is a substance that does not exist in an ionic form in aqueous solution. Nonelectrolytes tend to be poor electrical conductors and don't readily dissociate into ions when melted or dissolved. Solutions of nonelectrolytes do not conduct electricity.
Answer: He could add a base to the pool to neutralize the acid.
Explanation:
Chlorine is used to disinfect the pools as it produces hypochlorous acid in water. This hypochlorous acid is unstable and gives hydrochloric acid and nascent oxygen which is used to disinfect.

The excess acid is neutralized by adding base which produces salt and water and thus decrease the acidity.

Adding more acid would increase the acidity further.
Answer:
it can cause irritation in eyes throat and lungs and u can become lightheaded, or possibly fall in a coma
The small size and lack of structural tissues in phytoplankton mean that aquatic primary producers achieve faster growth rates and are more nutritious to heterotrophs than their terrestrial counterparts
The combustion reaction between propane and oxygen is
C3H8 + 5O2 → 3CO2 + 4H2O. The key in the balancing of chemical reaction is to
make sure that you got the exact chemical formula of the substance that is
reacting and the yielded product. After getting the formula, identify first the
hardest element/atom to be balanced such as Na, Zn, Cl, etc. Then proceed to
the easier ones such as O, H. Make sure to not the atoms present in the
molecule of the substance.
