Answer #1

Part A :

Balanced equation : O 2(g) + 2F 2(g) -> 2OF 2(g)

Part B :

According to the reaction,

1 mole O2 require 2 mole F2

3 mole O2 require 6 mole F2

Since we have only 4 moles of F2 hence F2 is limiting reagent.

Part C :

4 mole F2 give 4 moles of OF2.

% yield = actual product×100/expected product

= 3×100/4 = 75%
