Ever seen a waterfall ? what do you think happens when all that water slams into the ground below ? same as when you turn a hosepipe on a flowerbed.
also, there's hydraulic cracking where water gets into cracks and freezes, splitting rocks apart.
fast moving water can carry sediment and roll rocks along the bottom. if the water slows down, it drops the rocks and heavier sediment. if it floods a field, say, then drains away, the grass will also filter smaller particles out, or the water might evaporate and leave fine sediment behind.
PH INCLUDES ALL OF THE STATEMENT AND IT IS A SCALE WHICH CHECK THE ACIDIC AND BASIC BEHAVIOR OF SUBSTANCE OR SOLUTION
Answer: 7.29 g of 
will be produced from the given masses of both reactants.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 8 moles of 
Thus 0.0267 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 8 moles of
Thus 0.0267 moles of give = of
Mass of 
Thus 7.29 g of will be produced from the given masses of both reactants.
The answer is potential energy...
Hope this helped :)
