Answer: The correct chemical reaction is written below.
Step-by-step explanation:
Chemical equation is defined as the equation in which chemical substances are written on both the sides of the reaction. The reactants are written on the left side of the reaction arrow ad products are written on the right side of the reaction arrow.
If more than 1 chemical species is present, a '+' sign is added between the species.
The given chemical equation has a '+' sign missing. So, the chemical equation follows:

Hence, the correct chemical reaction is written above.
