If the pH of a 1.00-in. rainfall over 1300 miles2 is 3.90, how
many kilograms of sulfuric acid, H2SO4, are present, assuming that
it is the only acid contributing to the pH? For sulfuric acid, Ka1
is very large and Ka2 is 0.012.
If the pH of a 1.00-in. rainfall over 1300 miles2 is 3.30, how
many kilograms of sulfuric acid, H2SO4, are present, assuming that
it is the only acid contributing to the pH? For sulfuric acid, Ka1
is very large and Ka2 is 0.012. Express your answer to two
significant figures and include the appropriate units.
If the pH of a 1.00-in. rainfall over 1800miles2 is 3.40, how
many kilograms of sulfuric acid, H2SO4, are present, assuming that
it is the only acid contributing to the pH?
For sulfuric acid, Ka1 is very large and Ka2
is 0.012.
If the pH of a 2.54-cm rainfall over 3700 km2 is 3.20, how many
kilograms of sulfuric acid, H2SO4, are present, assuming that it is
the only acid contributing to the pH? For sulfuric acid, Ka1 is
very large and Ka2 is 0.012.
Express your answer to two significant figures and include the
appropriate units.
A buffer with a pH of 3.90 contains 0.15 M of sodium benzoate
and 0.30 M of benzoic acid. What is the concentration of [H ] in
the solution after the addition of 0.050 mol of HCl to a final
volume of 1.4 L?
A commercial bread bakery wants to evaluate its capacity, in
terms of how many kilograms of bread it can produce per hour. A
simplified version of the process is shown below:
In the mixing stage, all of the ingredients are combined to form
the dough.

Calculate the pH of an aqueous solution that is both 1.00 M
CH3COOH and 1.00 M CH3COONa. A
buffer solution is 0.24 M NH3 and 0.20 M NH4Cl. (a) What is the pH
of this buffer? (b) If 0.0050 mol
NaOH is added to 0.500 L of this solution, what will be the pH?
judy places 0.150kg of boiling water at 100° C in a
thermos bottle. how many kilograms of ice at -12.0°C must judy add
to the thermos so that the equilibrium temperature of the water is
75.0°C?
How many kilograms of water can be evaporated from a 1
m^2 surface in a lake on a hot summer day, if it is assumed that
the limiting factor is solar insolation (1000 W/m^22). Assume that
the length of the day is 8 hours and that the air and water temp
are at 40 degrees Celsius. B. What volume of air is needed to hold
this much water vapor at 40 oC. C. When the sun sets, the air
temperature...
