Explanation:

Question 22

Dihydrogen Monoxide is the chemical name for water ($H_2O$), and if the substance is water - based (or water itself), this would be the primary chemical. The other options: Neodecanoic Acid is a fatty acid, Methanol Silicate is a silicate compound, and Ethylene Glycol is used in antifreeze but the question likely refers to a common substance where Dihydrogen Monoxide (water) is the primary chemical.

For many common substances (especially those like water or mild chemicals), Nitrile Gloves and Safety Glasses are standard PPE. Goatskin Gloves are more for mechanical work, Face Shield and Chemical Apron are for more hazardous chemical handling, and a respirator is for airborne hazards. If the substance is relatively mild (like water or a mild solution), Nitrile Gloves and Safety Glasses are appropriate.

According to SDS (Safety Data Sheet) information for Prestone antifreeze, a common color for one of its versions is Yellow. Blue, Red, and Green are not the typical color for this specific version as per SDS.

Answer:

D. Dihydrogen Monoxide
