Answer:
The reactants Cu(SO)β and Naβ(NO)β are reacting to produce Naβ(SO)β and Cu(NO)β
Explanation:
When we describe a reaction by a chemical reaction, we put the reactants in on the side and the other side the products. A simple arrow (β) represents an irreversible reaction, the double arrow (β) represents a reversible reaction (the products are forming the reactants too).
So, for the reaction given, it's irreversible, and the reactants Cu(SO)β and Naβ(NO)β are reacting to produce Naβ(SO)β and Cu(NO)β.
