The answer is: The reactants were not heated long enough.
For all chemical reaction some energy is required and that energy is called activation energy (energy that needs to be absorbed for a chemical reaction to start).
Activation energy is the minimum energy colliding particles must have in order to react.
By lowering activation energy, reaction need less heat.
In this example, there is not enough heat.
The answer is B cotton, since you can grow it.
1 grams F2 to mol = 0.02632 mol
10 grams F2 to mol = 0.26318 mol
20 grams F2 to mol = 0.52636 mol
30 grams F2 to mol = 0.78954 mol
40 grams F2 to mol = 1.05272 mol
50 grams F2 to mol = 1.3159 mol
100 grams F2 to mol = 2.6318 mol
200 grams F2 to mol = 5.2636 mol
