a) Chemical properties are properties that become apparent when the compound is reacted with another compound while physical properties can be noted at any time. b) Intensive properties do not depend on the amount of the substance while extensive properties do. c) Chemical changes occur when the structure of the molecule changes but physical properties occur without the structure of the molecule changing. d) Mass is the amount of the substance while the weight is the force of gravity on the object.
Work Step by Step
a) Examples of chemical properties include the molecule's reactivity or their heat of combustion. Examples of physical properties include density or mass. b) Examples of intensive properties include colour or density. Examples of extensive properties include weight or volume. c) Chemical changes include a change in colour or heat being released. Physical changes include a change of size or shape. d) Weight depends on what planet the substance is on, the elevation and the mass. Mass is only dependent on the amount of substance that there is.
