The molecular formula of sulfuric acid is H2SO4. If I have 8.24 g of sulfur in a sample of sulfuric acid how many oxygen atoms are there?
Two aqueous sulfuric acid (H2SO4) solutions containing 20.0 wt% H2SO4 (SG=1.139) and 80.0 wt% H2SO4 (SG=1.727) respectively, are mixed to form a 4.00 molar solution (mol/L) (SG=1.213). Calculate the mass fraction of sulfuric acid in the product stream. Atomic weight: H=1g/mol, O=16g/mol, S=32g/mol. Taking 100 kg of the 20 wt% feed solution as a basis, calculate the volumetric feed ratio of 20.0 wt% H2SO4 to 80.0 wt% H2SO4, to 2 decimal places.
c) Initially, a tank is filled with 130 kmol of an aqueous sulfuric acid solution (H2SO4) which contains 5.0 mol% of H2SO4. The solution in the tank is concentrated by adding pure sulfuric acid at a rate of 20.0 L/min. i) Derive an equation to relate the mole balance of sulfuric acid with time. ii) Evaluate the time taken to concentrate the solution to 5%, 35%, 65%, 90% and 95% of H2SO4 and sketch a graph incorporating the values obtained....

One step in the manufacture of sulfuric acid is the oxidation of sulfur dioxide to sulfur trioxide. Consider performing this oxidation at a pressure of 1 bar with an excess of 100 mole % oxygen, using air as the oxygen source. For the optimal yield of SO3, it is desirable to maintain the reactor at a constant temperature of 700°C. You may assume ∆hrxn° is independent of temperature. What is the effect of increasing the pressure on the extent of...
