R-152A is a chemical compound consisting of which of the following elements?

  1. Hydrogen and Oxygen

  2. Nitrogen and Fluorine

  3. Hydrogen and Fluorine

  4. Carbon and Chlorine

The correct answer is: Hydrogen and Fluorine

R-152A, also known as 1,1-difluoroethane, is a hydrofluorocarbon (HFC) that primarily consists of hydrogen and fluorine. This compound has the chemical formula C2H4F2, which indicates that it contains both carbon and hydrogen atoms, as well as fluorine atoms. The presence of hydrogen and fluorine is key to its classification as an HFC, distinguishing it from other refrigerants that may contain different elemental compositions. The other options do not accurately reflect the elements that make up R-152A. The absence of oxygen, nitrogen, or chlorine in its molecular structure further confirms that the primary elements are indeed hydrogen and fluorine. Understanding the composition of refrigerants like R-152A is crucial in contexts such as environmental impact, regulation, and safe handling practices in HVAC applications.
