To be able to answer this item, one needs to use the proper dimensional analysis such that we arrive to the same unit of measures as given in the item. If we let x be the amount, in grams, of the certain substance then, we may use the equation,

                  409.20 kJ = (x g)(1 mol/59.25 g)(1430 kJ/mol)

The value of x from the equation is 16.95 g.

Answer: 16.95 g

What happens when you grow the same crop over and over again in the same field
irinina [24]

This is because the same type of </span>crop<span> planted repeatedly in the same area keeps draining the land of the same nutrients needed for that plant's growth. Pest can also plant their nest near the crop if the farmer continues to plant the same crop in the same place. 

Which is the reason why things such as "crop rotation" exist to keep things fresh, and prevent what I described above from happening.</span>
