Balance the half-reaction in acidic or basic solution then state whether the process is oxidation or reduction.
b) CLO4^-1 —> Cl2 (Basic)
c) FeO —> Fe2O3 (Acidic)
d)NO3^-1 —> N2O4 (Basic)

Ineed with a, b, c, d, and e on the long answer

Is this a single replacement reaction or there is no

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
