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

What is the mass of a solution that has a density of 0.775 g/ml and a volume of 50.0ml?
Margarita [4]
Hey there!

D = m / V

0.775 = m / 50.0

m = 0.775 * 50.0

m = 38.75 g

EastWind [94]

Answer:

the answer is D

Explanation:

Air over the beach heats up, rises, and is replaced by cool, denser ocean air

The ocean heats up much slower and becomes relatively cooler than the beach making it a high pressure zone. The air moves from the water to the land each morning forming a sea breeze. These pressure zones might equal out later in the day and the winds may diminish. ... A sea breeze blows from the ocean towards the beach.
