What type of representative particle does KClO3 have? atoms

formula units

molecules

formula units

Explanation:

 is  potassium chlorate. It is an ionic compound containing potassium, chlorine and oxygen. The ion in potassium chlorate are held together by the ionic bonds in the lattice structure.

A representative particle may be defined as the smallest unit for which the substance exists in its natural form. For most of the elements, atom is the representative particle. Molecule is the representative particle for diatoms and molecular compounds. But for ionic compounds such as   , NaCl, etc. . the representative particle is its formula units.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
