If the Suns heat is being reflected, then it is making the Earth cooler.
Explanation:
An ionic equation will be the one in which all the participating species will be present as ions.
The given reaction will be as follows.

Balancing this equation by multiplying
by 2 and
by 3 on reactant side. Whereas multiply KBr by 6 on product side.

Hence, the net ionic equation will be as follows.

As both
and
are spectator ions. Hence, the net ionic equation will be as follows.
