Final answer:
Hazard classes for the chemical based on the SDS label are corrosive, irritant, and potentially oxidizer, leading to the likely answer being b) Gas under Pressure, Corrosive, Irritant.
Step-by-step explanation:
According to the portion of the SDS label provided, the hazard classes that apply to this chemical are corrosive, irritant, and potentially oxidizer.
Corrosive chemicals, like hydrochloric acid, can cause burning to the skin, eyes, and can damage clothes.
Irritant chemicals, such as hydrogen peroxide, cause irritation to the eyes and skin.
Oxidizing agents contain oxygen that may cause other materials to combust, as seen in substances like potassium dichromate.
Based on this, the correct answer to the question is likely b) Gas under Pressure, Corrosive, Irritant, assuming that the chemical is also a gas under pressure, which isn't specified in the provided information but may be inferred from the provided SDS-esq label descriptions.
