It really depends on the 'type' of rock it is. By this I mean whether it's impermeable or permeable. Impermeable rocks don't allow water through and permeable rocks do. It has to do with how 'porous' a rock is: how many openings it has and how spaced apart are its particles are. Sandstone is permeable and Shale impermeable.
C.silicon and oxygen is the answer
Answer: 50.7 grams
Explanation:
To calculate the moles, we use the equation:

a) moles of 
![\text{Number of moles}=molarity\times {\text {Volume in L]}=0.417M\times 0.528L=0.220moles](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%7D%3Dmolarity%5Ctimes%20%7B%5Ctext%20%7BVolume%20in%20L%5D%7D%3D0.417M%5Ctimes%200.528L%3D0.220moles)
The balanced chemical equation is:

is the limiting reagent as it limits the formation of product and
is in excess.
According to stoichiometry :
2 moles of
give = 1 mole of 
Thus 0.220 moles of
give=
of 
Mass of 
Thus 50.7 g of
will be formed.
