Lakes that have been acidified by acid rain can be neutralized by limiting the addition of limestone how much limestone is requi
svet-max [94.6K]
From the given pH, we calculate the concentration of H+:
     [H+] = 10^-pH = 10^-5.5
We then use the volume to solve for the number of moles of H+:
     moles H+ = 10^-5.5M * 4.3x10^9 L =  13598 moles
From the balanced equation of the neutralization of hydrogen ion by limestone written as
     CaCO3(s) + 2H+(aq)  → Ca2+(aq) + H2CO3(aq)
we use the mole ratio of limestone CaCO3 and H+ from their coefficients, which is 1 mole of CaCO3 is to react with 2 moles of H+, to compute for the mass of the limestone:
     mass CaCO3 = 13598mol H+(1mol CaCO3/2mol H+)
                               (100.0869g CaCO3/1mol CaCO3)(1kg/1000g) 
                            = 680 kg

Infer: Why might a zone of upwelling be a good place to fish?
Aleks [24]

First lets define upwelling

Upwelling- a rising of seawater, magma, or other liquid

In this case, you would be looking at a river, lake, ocean, or other body of water good for fishing.

You'd want to look for a place with upwelling because when there is a rise of water, the sea creatures within it will rise too. So the fish in the bottom of a lake for example would be brought up to the surface of the water or near the surface which is where your fishing rod is trying to grab the fish.

I hope this helps! Don't be afraid to reach out with any further questions!
