Determine the representative particles in each substance?
A.) 4.45 mol of C6H12O6
B.) 0.250 mol of KNO3
C.) 2.24 mol of H2
D.) 9.56 mol of Zn
A representative particle is the smallest unit of a substance that can be broken down without altering the composition. There are three types of particles: molecules, structural units(like ions) and atoms. If we have covalent bonded substance - representative particle will be molecule. When we have some chemical element - this particle is atom. When we have ionic compound - representative particles are ions. A.) molecules of glucose B.) ions K+ and NO3- C.) molecules of H2 D.) atoms of Zn
