R-152 is a compound that consists of which elements?

R-152, also known as 1,1-difluoroethane, is a refrigerant compound that is composed of carbon and hydrogen along with fluorine. To clarify, the molecular formula for R-152 is C2H4F2, indicating it includes carbon (C), hydrogen (H), and fluorine (F).

The correct answer is provided as Hydrogen and Fluorine; while this seems to address part of the composition, it does not explicitly mention carbon, which is a significant component. This might cause confusion, as the elements in R-152 include carbon in addition to hydrogen and fluorine.

In the context of the other choices, sodium and chlorine, oxygen and nitrogen, or just carbon and fluorine do not apply to R-152 as they either lack essential elements found in the actual compound or do not represent its molecular structure at all. Understanding the full molecular composition is crucial for recognizing the specific elements that make up refrigerants like R-152.
