Which of the following pairs is mismatched? a. sodium hypochlorite-chlorine b. formalin-formaldehyde c. iodophor-iodine d. phenolics-peracetic acid e. benzalkonium chloride-quaternary ammonium compound

The mismatched pair is : D. phenolics-peracetic acid

Explanation:

A. sodium hypochlorite-chlorine: Correct pair

Sodium hypochlorite solution (NaOCl) is made from the reaction of chlorine and sodium hydroxide solution.

B. formalin-formaldehyde : Correct pair

The formalin solution is a 37% aqueous solution of formaldehyde.

C. iodophor-iodine : Correct pair

Iodophor, a combination of iodine and solubilizing agent. When diluted with water, iodophor releases free iodine.

D. phenolics-peracetic acid : wrong pair

Phenolics is a noun used for phenols, aromatic hydrocarbons with a hydroxyl group. Whereas, peracetic acid or peroxyacetic acid is an organic peroxide.

E. benzalkonium chloride-quaternary ammonium compound: Correct pair

Benzalkonium chloride is a quaternary ammonium organic salt, used as a cationic surfactant.

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
