Concept introduction:
The contact process is the method of producing sulfuric acid in the high concentrations needed for industrial process. The process involved combining of sulfur and oxygen to form sulfur dioxide as follows,
Adding an excess of oxygen to sulfur dioxide in the presence of catalyst, the sulfur trioxide is formed. The sulfur trioxide is added to sulfuric acid which gives rise to disulfuric acid (oleum). Oleum is reacted with water to form concentrated sulfuric acid. The reactions involved is written as follows:
(b)
Interpretation:
To calculate the mass of calcium hydroxide is needed to remove the sulfur dioxide.
Introduction:
In the contact process, for making sulfuric acid, if enough sulfur is burned to sulfur dioxide to produce anhydrous sulfuric acid. The sulfur dioxide is vented to the atmosphere. To prevent any

- 4.48 Elemental phosphorous is used in the semiconductor industry. It can be obtained from an ore called fluoroapatite via reaction with SiO2 and C: 4Ca5( PO4)3F+18SiO2+30C3P4+30CO+18CaSiO3+2CaF2 Suppose a particular semiconductor production plant requires 1500 kg of P4. If the recovery of P4 from this reaction is 73% efficient, what mass of fluoroapatite is needed?arrow_forwardCalcium oxide, CaO, is used to remove SO2 from power plant exhaust. These two compounds react to give solid CaSO3. What mass of SO2 can be removed using 1.2 103 kg of CaO?arrow_forwardAlumina, Al2O3, is amphoteric. Among examples of its amphoteric character are the reactions that occur when Al2O3 is heated strongly or fused with acidic oxides and basic oxides. (a) Write a balanced equation for the reaction of alumina with silica, an acidic oxide, to give aluminum metasilicate, Al2(SiO3)3. (b) Write a balanced equation for the reaction of alumina with the basic oxide CaO to give calcium aluminate, Ca(AlO2)2.arrow_forward
