Ascientist observed a 5-ml sample of an unknown substance. it is a blue liquid with a density of 1.2 g/cm. the substance reacts with carbon dioxide. lust each of the properties the scientist observed and whether it is a characteristic property of matter.

Characteristic properties can be used to describe and identify the substances, while non-characteristic properties, although can be used to describe the substances, cannot be used to identify them.

Temperature, mass, color, shape and volume are examples of non-characteristic properties.

Density, boiling point, melting point, chemical reactivity are examples of characteristic properties.

List of the properties observed by the scientist:

Property                                     Type of property

Volume: 5 ml                              non-characteristic

Color: blue                                 non-characteristic

State: liquid                                characteristic

density: 1.2 g/cm                        characteristic

Reaction: reacts with CO2         characteristic
