Answer:
Cl2 + 2NaBr --> 2NaCl + Br2
Explanation:
This is a single displacement reaction where one side of the ionic compound switches with the other.
So, Cl2 + NaBr ---> NaCl + Br2
This isolates the Bromine and puts the Chlorine in it's place.
Then, balance out the equation like so and you should get
Cl2 + 2NaBr --> 2NaCl + Br2
An increase in temperature increases the average kinetic energy of molecules.
When the temperature of a molecule increases, the molecule starts to move at a faster rate. The faster a molecule moves, the more kinetic energy it has.
