Answer choice B 259 kelvins
A reducing agent is one which is oxidised in the reaction itself. When you take into account the oxidation numbers you will see that the Cl- ions are oxidised from an oxidation number of -1 to 0 in Cl2. Therefore Cl- ions are the reducing agent.
Star clusters is the only thing i can think of that would apply.
4, 2, 1, and 3 is the answer
Answer:
The net ionic equation for the given reaction :
Explanation:
...[1]
..[2]
...[3]
Replacing 
, NaI and 
in [1] by usig [2] [3] and [4]
Removing the common ions present ion both the sides, we get the net ionic equation for the given reaction [1]:
