Define a pure compound refrigerant and give two examples?
Oh, dude, a pure compound refrigerant is like a single substance made up of only one type of molecule, no mix and match here. So, like, examples would be R-134a, which is used in air conditioners and refrigerators, and R-410A, which is also used for cooling stuff. It's like having a one-track mind, but for refrigerants.

Define compound and molecule?

What is the propites of the elements?
Different elements all have very different properties. However, you can define an element as a substance with only one type of atom in (e.g. only sulphur atoms). If a substance has more than one type of atom in, then it is either a compound or a mixture, depending on whether the elements have bonded.
Define a solution?
