Question

physical chemistry studies what specifically? * 1 point
polymers
carbon based compounds
the isolation and understanding of chemical compositions for use
physics principles to explain chemical reactions

polymer chemistry studies what? * 1 point
carbon based compounds
molecular structures made up of similar units bonded together
the physics of chemical reactions
life processes

these can be observed without changing the substance. they include things like appearance, texture, color, odor, melting point, boiling point, density, and solubility * 1 point

Explanation:

Physical chemistry uses physics principles to explain chemical reactions. Polymer chemistry focuses on molecular structures made up of similar units bonded together. Physical properties can be observed without changing the substance and include characteristics like appearance, etc.

Answer:

1. D. Physics Principles to explain chemical reactions
2. B. Molecular structures made up of similar units bonded together
