The correct answer is option 3 and 5.

Compounds are made up of a mixture of 2 or more elements such as H₂O or NaCl.

Compounds have physical properties that are constant and hence allow us to identify them. Different physical properties include color, solubility, mass, odor, density, boiling point, melting point etc
