The following table gives the total amounts of water and salt in the oceans and the total influx of water and salt from rivers each year. Use this information to calculate the residence time in the world ocean of both water and salt. Water Salt TOTAL Oceans 1.4x10^18 tons 5x10^16 tons AMOUNT ΤΟΤAL Rivers 26.4x10^12 tons/yr 2.7x10^9 tons/yr INFLUX Residence time = amount in ocean/rate of addition or removal

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
