253243 How many metric tons of 5%-S coal would be needed to yield the H2SO4 required to produce a 1.5-cm rainfall of pH 2.00 over an area of 100 square kilometers?
The solution calculates the amount of coal needed to yield the H2SO4 required to produce a 4.5 cm rainfall of pH 2.00 over an area of 100 square kilometers.
41786 Producing a Rainfall Using H2SO4 Producing a Rainfall Using H2SO4 It is best to break this one into parts.
Volume of the rain to cover 100 square kilometers with 4.0 cm of rainfall.
This solution gives the amount of metric tons of 5%-S coal needed to produce a given amount of pH over a specified area.
29558 Amount of Coal Needed to Produce a pH of 2 Amount of Coal Needed to Produce a pH of 2 The concentration is [H+] is 10^-pH. e.g If the pH is 5 then [H+] is 10^-5 mol/L
Because H2SO4 gives two H+ ions, the concentration of H2SO4 is half that
Now, we need to know how much coal it would take to produce this many joules.

Yinon It finds the amount of metric tonnes of 5%-S coal that could produce
At this rate, what mass of 235U (kg) would it consume per year if the efficiency of converting nuclear energy to electricity is 33%? How many metric tons of coal would be required to supply the same amount of electricity?
Next we need to determine how many hectacres are in a square km.
One sq. km = 100 hectares
So we know that we are dealing with 50,000,000 x 100 = 5 billion hectares. We need it to produce a total of 200 EJ, or 200 billion GJ.
The radius of a solid sphere is measured to be (6.50 ± 0.20) cm, and its mass is measured to be (1.85 ± 0.02) kg. Determine the density of the sphere in kilograms per cubic meter and the uncertainty in the density.
