The activity series shows the order of reactivity of elements. The reaction Br2 + NaF -----> does not occur because bromine is less than fluorine in the activity series.
The activity series shows the order of reactivity of elements. The elements that are higher in the activity series will displace the elements that are lower in the activity series.
The activity series of halogens is shown as; F > Cl > Br > I. Let us consider the reaction; Br2 + NaF ----->
We can see that bromine is less than fluorine in the activity series hence there will be no reaction because bromine can not not displace fluorine.

Let us assume number of toppings = n
Total weight of sundae = s
Quantity of Ice cream = 2 kilograms.
We need to discribe the total weight of the special sundae in kilograms by an inequality.
The sundae contains ice cream and number of toppings.
So the total weight of the sundae will be greater than the total weight of ice cream and number of toppings, because there would be some weight of the packing.
Therefore,
The total weight of the sundae > total weight of ice cream + weight of toppings.
s > 2 + n.
Where, s is the total weight of the sundae and n is the weight of toppings. I hope this was helpful!. :)
