<span>Erosion by wind or water transports the rock particles and sediments to other sooner or later hitting the ocean.then the rocks form together to make sediment rock! :D</span>
Well, if the coefficients are both 1, then you will make 8.21 moles.
See the equation is:
x moles= (8.21mol FeS₂)×(1 mole H₂SO₄ ÷ 1 mole FeS₂) = 8.21 moles H₂SO₄
So if you change the coefficients of the equation, your product will be a different number.
Example:
x moles= (8.21mol FeS₂)×(2 mole H₂SO₄ ÷ 1 mole FeS₂) = 16.4 moles H₂SO₄
I hope this helps you out!

(a) at the bottom - high density organic compound dissolved in methylene chloride
(b) at the bottom - saturated aqueous sodium chloride
Explanation:
Sodium chloride is dissolved in water while the organic compounds are dissolved in methylene chloride. After mixing the two solutions two layers will form because water (polar molecule) will not mix with the methylene chloride (nonpolar molecule).
The layer with higher density will be at the bottom.
(a) saturated aqueous sodium chloride (d = 1.2 g/mL) - upper layer
high density organic compound dissolved in methylene chloride (d = 1.4 g/mL) - bottom layer
(b) saturated aqueous sodium chloride (d = 1.2 g/mL) - bottom layer
low density organic compound dissolved in methylene chloride (d = 1.1 g/mL) - upper layer

Don’t currently have a calculator with me but just use Avogadros constant (A) 6.02x10^24, in the equation n=N/A. Lower case n being the number of mol and upper case being the number of molecules (given).
