Answer 1 )
Br2 is above the I2 in the activity series of the non metals, so reaction will take place and Br2 will replace the I2.
Using the Activity series predict and balance the following single replacement reactions. For the reaction that do not occure, write no reaction
1) Liquid Bromine is added to a container of sodium iodide crystals
2) Fe(s) + CuS O 4 (aq) →
3) B r 2 (l) + MgC l 2 (aq) →
